Program for testing the system in games. Utilities for determining computer hardware

Hi all. In today's article, we will talk about a complete diagnosis of all devices in your computer. I will show and tell you how to independently diagnose a computer and all its component devices:

• HDD.
• RAM.
• Video card.
• Motherboard.
  
• CPU.
• Power Supply.

We will check all this in this article and for each of the computer devices I will make a video in which I will clearly show how to diagnose a particular device.

In addition, by diagnostics, you will be able to determine whether you should completely change the device or you can repair it, we will also analyze the main sores of devices that can be determined without diagnostics. Well, let's start with the most important question of interest to everyone - the diagnosis of the HDD / SSD disk.

HDD and SSD disk diagnostics.

Disk diagnostics are done in two directions, they check the Smart systems of a hard or solid state drive and check the disk itself for bad or slow sectors in order to check the SMART HDD and SSD, we will use the program. You can download it from our website in the download section.

Well, now let's go directly to the disk diagnostics itself, after downloading the program, launch the file of the required bitness and look at the main window, if you see a blue icon with the signature good or in English good, then everything is in order with your SMART disk and further diagnostics can not be carried out.

If you see a yellow or red icon with caution, bad inscriptions, then there is some problem with your disk. You can find out about the exact problem below in the list of basic SMART diagnostic items. Wherever there are yellow and red icons opposite the inscription, it will indicate that your disk has suffered in this part.

If you have already exhausted the resource of the disk, then it is no longer worth repairing it. If you have found several broken sectors, then there is still the possibility of repair. I will talk about the repair of bad sectors later. If the disk has a lot of bad sectors, more than 10 or a lot of very slow sectors, then you should not restore such a disk. After a while, it will still fall further, it will need to be constantly restored / repaired.

Software disk repair.

By repair, I mean the relocation of bad and slow sectors on the disk. This instruction is only suitable for HDD drives, that is, only hard drive. For SSD, this operation will not help in any way, but will only worsen the condition of the solid state drive.

Repair will help extend the life of your hard drive a little more. To restore bad sectors, we will use the HDD regenerator program. Download and run this program, wait until the program collects data about your drives after the data is collected, you will see a window in which you will need to click on the inscription - Click here to bad sectors on demaget drive surfase directly under Windows XP, Vista, 7, 8 and 10. You need to click on the inscription quickly in OS 8 and 10, so the window will quickly disappear, in 7 everything is fine. Then press NO. Then select your drive from the list. Press the start process button. A command line window will appear in which you will need to press 2, Enter, 1, Enter.

After the performed operations, the system will start scanning for bad sectors and moving them to unreadable disk partitions. In fact, bad sectors do not disappear, but in the future they do not interfere with the operation of the system and you can continue to use the disk further. The process of checking and restoring the disk may take a long time, depending on the size of your disk. At the end of the program, press the button 5 and Enter. If you have any errors while testing and fixing bad sectors, then your disk cannot be recovered. If you have found more than 10 bad sectors, then restoring such a disk does not make sense, there will always be problems with it.

The main signs of disk failure are:

RAM Diagnostics

This time we will run a memory diagnostic. There are several options in which you can check the RAM, this is when your computer still turns on and somehow works, and when you can’t turn on the computer, only the BIOS is loaded.
The main signs that the RAM is not working:

• When loading resource-intensive applications, the computer freezes or restarts.
• With prolonged use of the computer, more than 2 hours, Windows starts to slow down, with an increase in time, the slowdown increases.
• When installing any programs, you cannot install them, the installation fails.
• Sound and visual jamming.

The first thing we will cover is how to check the RAM if your Windows boots. It's very simple, in any of the operating systems starting with Windows Vista, you can type the Windows memory test tool in the search. We launch the shortcut that appears as an administrator and see a message stating that you can reboot and start checking right now or schedule a check the next time you turn on the computer. Choose the value you need. After the computer restarts, you will immediately automatically start the RAM test. It will be carried out in standard mode, wait until the end of the test and you will find out if everything is in order with your RAM. In addition, after you have already loaded Windows, in the event viewer section you can open the Windows logs, select the System item and find the memory diagnostic event in the list on the right. In this event, you will see all the information about the diagnostics performed. Based on this information, you can find out if the RAM is working.
The next option for diagnosing RAM is if you cannot boot Windows. To do this, you need to write the program to a disk or to a bootable USB flash drive and run it from the BIOS. In the window that appears, a test to check the RAM (RAM) will be automatically launched. Wait until the end of the test and if there are any problems with your memory, the test window will change from blue to red. This will indicate defects or damage to the RAM. That's all, you have learned - how to diagnose RAM.

Video on how to check the RAM:

Video card diagnostics

The main signs of a defective video card:

• Computer throws blue screen of death.
• Artifacts appear on the screen - multi-colored dots, stripes or rectangles.
• When downloading games, the computer freezes or restarts.
• With prolonged use of the computer in the game, performance decreases, the game starts to lag.
• Video jamming, video playback failure, problems with the flash player.
  
• Lack of smoothing in text and when rewinding documents or web pages.
• Changing colors.

All these are signs of some kind of video card defects. Testing a video card should be divided into two stages: checking the graphics chip and checking the memory of the video card.

Checking the graphics chip of the video card (GPU)

To check the graphics chip, you can use various programs that put a load on this chip and detect failures under critical load. We will use the program and FurMark.
We launch Aida at the bottom in the tray near the clock, right-click and select the system stability test. in the window that appears, check the box next to GPU Stress Test. The test will run at the bottom you will see a graph of temperature changes, fan speed, and current consumption. To check, 20 minutes of the test is enough, if at this time the bottom field with the graph turns red or the computer restarts, then there are problems with your video card.
We start OCCT. Go to the GPU 3D tab, do not change the settings and press the ON button. Next, a window will appear with a fluffy donut, which is a visual test. The test will take 15-20 minutes. I recommend monitoring the temperature and monitoring the power readings, if multi-colored dots, stripes or rectangles appear on the screen, this will indicate that there is a problem with the video card. If the computer turns off spontaneously, this will also indicate a defective video card.
Now we have analyzed the diagnostics of the video card processor, but sometimes there are problems with the memory of the video card too.

Video card memory diagnostics

For this diagnosis, we will use the program. Unpack the program and run it as administrator. In the window that appears, check the box next to the inscription signal if there are errors and press the start button. A check of the RAM of the video card will be launched if any errors with the memory are found, the program will emit a characteristic sound signal, on some computers the signal will be a system one.
That's all, now you can do video card diagnostics yourself. Check the GPU and memory of the video card.

Video on checking the video card:

Motherboard Diagnostics

The main signs of a motherboard malfunction:

• The computer knocks out the blue screen of death, reboots and turns off.
  
• The computer freezes without restarting.
  
• The cursor, music and video (friezes) stick.
  
• Connected devices disappear - HDD / SSD, drive, USB drives.
  
• Ports, USB and network connectors do not work.
• The computer does not turn on, does not start, does not boot.
• The computer is slow, often slows down or freezes.
• The motherboard makes various sounds.

Visual inspection of the motherboard

The first thing to do to diagnose the motherboard is to conduct a visual inspection of the motherboard. What you need to pay attention to:

• Chips and cracks - in the presence of such damage, the motherboard will not turn on at all or will turn on after a time.
• Swollen capacitors - due to swollen capacitors, the computer can turn on with 3, 5, 10 attempts or after a certain time, it can also go out for no reason and slow down.
  
• Oxidation - the computer can turn on after a time, slow down. It may not turn on at all if the tracks are completely oxidized.
• Warmed chips, microchips will have small burning points or holes - because of this, the computer may not turn on or ports, network cards, sound or USB will not work.
• Scratches on the tracks - the same as with chipped cracks.
• Burn around chips and ports - leads to the complete inoperability of the motherboard or its individual parts.

Software diagnostics of the motherboard

If your computer turns on and Windows boots, but there are incomprehensible glitches and slowdowns, you should do software diagnostics of the motherboard using the program. Download and install the program, run it, at the bottom in the tray near the clock on its icon, right-click and select "service" - "system stability test". Check the boxes next to Stress CPU, Stress FPU, Stress cache, remove the rest of the checkboxes. We press the "Start" button, the computer will freeze, the test will begin. During the test, monitor the temperature of the processor and motherboard, as well as power. The test is carried out for a minimum of 20 minutes, a maximum of 45 minutes. If during the test the bottom field turns red or the computer goes out, then the motherboard is faulty. Also, the shutdown may be due to the processor, uncheckStress CPU and check again. If you find overheating, then you need to check the cooling system of the motherboard and processor. with power fluctuations, there may be problems with both the motherboard and the power supply.

If the computer starts but Windows does not boot, you can check the mainland through the boot test. It must be written to a disk or flash drive. I'll show you how to use it in more detail in the video.

Diagnostics of the power supply unit (PSU)

The main symptoms of a power supply failure:

• The computer does not turn on at all.
• The computer starts for 2-3 seconds and stops working.
• The computer turns on from 5-10-25 times.
• Under load, the computer goes dead, reboots or throws out a blue screen of death.
• When under load, the computer slows down a lot.
• Devices connected to the computer spontaneously disconnect and reconnect (screws, drives, USB devices).
• Squeak (whistling) during computer operation.
• Unnatural noise from the PSU fan.

Visual inspection of the PSU

The first thing to do if the power supply fails is to make a visual inspection. We disconnect the PSU from the case and disassemble the PSU itself. We check for:

• Cinder, melted PSU elements - we look that all the elements are intact, if you find a cinder or something obviously melted, we carry the PSU for repair or change it to a new one.
• Swollen capacitors - replace swollen capacitors with new ones. Because of them, the computer may not turn on the first time or go out under load.
• Dust - if dust is clogged in the fan and radiators, it must be cleaned, because of this, the PSU in the load may turn off due to overheating.
• Blown fuse - a fuse often burns when there is a voltage drop, it must be replaced.

We checked everything, but the power supply is behaving badly, we look.

PSU software diagnostics

Software diagnostics of the power supply can be carried out using any test program that gives the maximum load on the PSU. Before doing such a check, you need to determine whether all the elements of your PC have enough power from the power supply. You can check this as follows: run the AIDA 64 program link above and go to the site for calculating the required PSU power. On the site, we transfer the data from Aida to the appropriate fields and press the Calculate button. So we will be sure exactly how much power the power supply is enough for the computer.

We proceed to the diagnosis of PD itself. We download the program. Install and run it. Go to the Power Supply tab. check the box to use all logical cores (does not work on all computers) and press the ON button. The test lasts an hour and if at this time the computer turns off, restarts, knocks out a blue screen, there are problems with the power supply unit (Before checking the power supply unit, you must first check the video card and processor in order to avoid the test being incorrect).

I won’t show how to make a PSU diagnostic with a multimeter, because there is a lot of this information on the network, and it’s better for professionals to do such diagnostics. I will show more testing of the PSU in the video below:

A free program for diagnosing a computer, identifying installed devices and programs, and testing its performance.

I will not say that very often, but sometimes we need to find out all the data about our computer. You were going, for example, to lay out a certain amount of hard-earned money for the purchase of a new super-mega game. We bought it, but it flatly refuses to start, because your system does not have enough RAM or video card power.

In order not to repeat such misunderstandings, I advise you to always use programs to determine the configuration of your computer. Many people use such famous packages as Everest or SiSoftware Sandra Lite for this purpose.

But, since the first is paid, and the second has a rather large distribution, we will look for an alternative. And she is!

Meet the third player in the computer testing arena - PC-Wizard. The English company CPUID, also known for its product CPU-Z, tried to make a free, but quite competitive program. And she succeeded.

Benefits of PC-Wizard

• small size of the installation distribution (zip-archive 3 megabytes);
• full and deep PC analysis;
• availability of tools for benchmarking (system tests);
• clarity of presentation of information;
• simplicity and clarity of the interface;
• the ability to view hidden system files.

As they say, why pay more :). To better understand the features and capabilities of PC-Wizard, let's download and install it on your computer. Installed? Now let's run the program and wait a few seconds while it checks the configuration of your PC.

Before you is the main window, which displays general information about the system.

PC-Wizard Interface

The program window is divided into several zones. On the left is the menu for selecting the tested components, on the right is the details window. The latter has two parts. General information is displayed at the top, but if you click on one of the list components, detailed information about the selected item is displayed at the bottom.

Interestingly, if you minimize PC-Wizard, it will display information about your processor.

There are several menu items on the left side. These are Hardware, Configuration, System Files, Resources and Test. Let's deal with everyone in order.

Information about computer components

Using the "Hardware" menu, you can find out everything about the hardware of your computer. This is general information about the system, motherboard, processor, video subsystem, I / O ports, CD / DVD drives, printers, connected devices, audio subsystem, network, power status and temperature.

In order to view information about a particular component, select the section you are interested in and all the data about it will be displayed in the field on the right.

The "Configuration" menu allows you to view information about the software component of the computer.

Information about installed programs

There are already 21 points, so there is something to explore. Among the features worth noting is the ability to obtain information about Windows, control panel settings, running processes, startup, and others. An interesting opportunity is also to see the statistics of system downloads (for some reason, the name remained in English - UpTime statistics.

Information about system files

In the "System Files" menu, you will see information about all the files that are responsible for the operation of the system.

Among them are files such as Boot.ini, Config.nt, System.ini, Event Log and others. An interesting item is also "CMOS Values". With it, you can view the CMOS settings of your PC (but, unfortunately, not configure :).

Ports and other resources

The Resources menu displays highly specialized information about the ports involved and some properties of individual system components.

Computer Performance Testing Tools

And finally, the last menu is "Test". This menu gives you the opportunity to perform some performance tests on the system and its individual components.

There are both standard tests (system performance, processor test, video subsystem test, memory tests ...) and more exotic ones (processor computing ability test and mp3 compression speed test).

The advantage is the ability to view the test results in the form of a graph (you can save it by pressing F11), as well as the ability to compare the results of your test with the results of testing other PCs (click the "Compare with ..." button).

Additional functions

In addition, the program has a number of other functions. All data can be saved to a file (the “Save as” button), printed (the “Print” button, respectively), copied to the clipboard (“Copy”), or sent as a report to your email (for this, a mailbox must be created in the mailbox). MS Outlook agent).

PC-Wizard also has a function to search for the file you need (the "Find file" button). By clicking on the "Next" button, you will be able to see your network environment (unfortunately, you will not be able to view the contents of folders on other computers).

The "Device Manager" button displays brief information about all the components of the computer, "Overclocking Information" will help you quickly get basic information about the timings, temperatures and frequencies of the processor, video card and memory.

There are two more points without which our review would be incomplete. If you go to the "Tools" menu, you will see two untranslated items in English. Especially you may not need them, but we are obliged to consider them. The first one is System Test Stability. It is another test of the stability of the processor and motherboard.

Principle of operation: the processor is loaded to the maximum and in such conditions it works for a long time. At the same time, measurements of its temperature and the temperature of the motherboard are made. It should not exceed 100°C for the processor and 60°C for the motherboard.

The second item we'll look at is Processor Monitoring. This is almost a standard Windows performance manager with a slightly modified interface. It allows you to track the loading history of the processor core, frequency of operation and voltage.

The program has practically no disadvantages, but it is worth paying attention to the shortcomings of the translators (not all points are translated into Russian), as well as some bugs (I found two - who is more :).

conclusions

In general, I have a positive opinion about PC-Wizard. There is nothing superfluous here, the program consumes few resources, is quite easy to manage and undemanding to the settings. Although its obviously rustic design may not be to everyone's taste, but there are no comrades for taste and color :).

P.S. It is allowed to freely copy and quote this article, provided that an open active link to the source is indicated and the authorship of Ruslan Tertyshny is preserved.

Sometimes it is simply necessary to diagnose the system. The main goal is to get detailed data about your hardware. This can be done using special software. It is difficult to say which is the best program for determining computer hardware. Let's look at the most popular of them and draw conclusions about which one is worth using and which one is not.

Overview AIDA 64

You must have heard of this one is highly functional and easy to use. Perhaps this is the most popular software for checking the hardware of your computer or laptop. The utility provides the most detailed information about your operating system, drivers, hardware, programs, etc. A distinctive feature is that Aida 64 allows you to monitor, that is, monitor the stability of your computer both during downtime and under loads. You will be able to speed coolers and much more. If you need real-time information, then AIDA 64 is a good program for determining computer hardware. But the possibilities of the utility do not end there. Let's talk about additional features.

A program for checking computer hardware or all the features of Aida

As noted above, there is currently a lot of software that allows you to find out all the details of the operating system and in general. But not all programs allow you to perform stress tests that are necessary to verify stability. This is especially necessary after overclocking a processor or video card in order to find out how the component will behave at elevated temperatures, loads, etc. If you are going to update your device, then first you need to do a test that will show where the most vulnerable spot is and what you need to pay attention to first. In addition to all this, "Aida 64" allows you to monitor in real time. This is useful when you need to know the temperature of the processor or video card while performing certain tasks (watching multimedia, playing games, etc.)

A small guide about sections of Aida 64

We have already said almost everything about the capabilities of the utility, and now let's go through the sections. If necessary, you can get detailed information about. Moreover, the program for determining computer hardware and searching for drivers "Aida" will help you find out even the most detailed information about components that have just gone on sale. You can also find out the features of the device's power supply, BIOS settings, and much more. If you go to the "Motherboard" menu, you can find out everything about your processor. These are frequency, temperature, cooler speed and more. By visiting "Storage", you can find out details about your hard drives and other connected drives.

Determination of computer hardware using SoftwareSandra

This is another fairly informative utility that allows you to get general information about the system. If you do not need detailed information, but only generalized data about the computer, then this is what you need. However, in addition to a large amount of summary information, there is more detailed information. To get it, you need to go to the "Devices" tab and select the component you are interested in there. It can be a memory bus, a processor, a port, or a video card. In principle, this is all that concerns your iron. If we talk about monitoring, as in the AIDA utility, then it is here. The only difference is that it is designed as a diagnostic rather than a purely informational module. You can get here all the necessary information about the temperature of the processor, video card, cooler rotation speed, etc. The utility is good because it does not load your system, it works quite quickly and stably. It is completely free, so you do not need to go through activation or pay anything.

Determination of performance using standard OS tools

If there is no desire to download something from the Internet, or such an opportunity is simply not available, then you can go the other way - use the application built into the operating system. It is not as informative as the utilities described above, but nevertheless, the data obtained will be quite enough for you to identify weaknesses. This program for determining the computer and setting its power is available to all users of OS Win 7, 8, Vista. You need to go to "My Computer" and select "Properties". You will see a box called "System". It provides general information about the amount of RAM, installed processor, etc. There is also a line "Windows Experience Index". Go there and you will be able to see the score from one to eight. The higher it is, the better the individual component of your computer works. If the processor rating is 3, and the video card is 6, then the first component is the weak link, so it is this one that needs to be changed first.

Instead of a conclusion

In principle, you have received a lot of useful information and learned about which program for determining computer hardware can be used. Do not forget that stress tests are not recommended to be done too often, as this will negatively affect the system components - they should not work with overload, and if they should, then rarely and not for long. You can get a sufficient amount of information if you go to "Start" - "All Programs" - "System Tools" and "System Information". Most of the comprehensive information can be taken from here, but if you want to perform a monitoring or stress test, then you need to download "Aida 64" or something like that.

Many PC owners are faced with various errors and failures in the computer, but cannot determine the cause of the problem. In this article, we will look at the main ways to diagnose a computer, allowing you to independently identify and fix various problems.

Keep in mind that high-quality computer diagnostics can take a whole day, allocate it in the morning specifically for this, and do not start everything in the late afternoon.

I warn you that I will write in detail as for beginners who have never disassembled a computer in order to warn about all the possible nuances that can lead to problems.

1. Disassembling and cleaning the computer

When disassembling and cleaning the computer, do not rush, do everything carefully so as not to damage anything. Store the accessories in a safe place prepared in advance.

It is not advisable to start diagnostics before cleaning, since you will not be able to identify the cause of the malfunction if it is caused by clogged contacts or the cooling system. Additionally, diagnostics may fail to complete due to repeated failures.

Unplug the system unit from the outlet at least 15 minutes before cleaning to allow the capacitors to discharge.

Perform disassembly in the following sequence:

1. Disconnect all wires from the system unit.
2. Remove both side covers.
3. Disconnect the power connectors from the video card and remove it.
4. Remove all memory sticks.
5. Disconnect and remove the cables from all drives.
6. Unscrew and remove all discs.
7. Disconnect all power supply cables.
8. Unscrew and remove the power supply.

There is no need to remove the motherboard, CPU cooler, case fans, you can also leave the DVD drive if it works fine.

Gently blow out the system unit and all components individually with a powerful stream of air from a vacuum cleaner without a dust bag.

Carefully remove the cover from the power supply and blow it through without touching the electrical components and the board with your hands and metal parts, as there may be voltage in the capacitors!

If your vacuum cleaner does not work for blowing out, but only for blowing in, then it will be a little more difficult. Clean it well so that it pulls as hard as possible. We recommend using a soft bristle brush when cleaning.

You can also use a soft brush to remove stubborn dust.

Thoroughly clean the CPU cooler heatsink, first considering where and how much dust it has clogged with dust, as this is one of the common causes of CPU overheating and PC crashes.

Also make sure that the cooler mount is not broken, the clamp is not open and the heatsink is firmly pressed against the processor.

Be careful when cleaning the fans, do not let them spin too much and do not bring the vacuum cleaner nozzle close if it is without a brush, so as not to beat off the blade.

At the end of cleaning, do not rush to collect everything back, but proceed to the next steps.

2. Checking the motherboard battery

The first thing after cleaning, so as not to forget later, I check the battery charge on the motherboard, and at the same time reset the BIOS. In order to pull it out, you need to press the latch with a flat screwdriver in the direction indicated in the photo and it will pop out by itself.

After that, you need to measure its voltage with a multimeter, optimally if it is in the range of 2.5-3 V. The initial voltage of the battery is 3 V.

If the battery voltage is below 2.5 V, then it is advisable to change it already. The voltage of 2 V is critically low and the PC is already starting to fail, which manifests itself in resetting the BIOS settings and stopping at the beginning of the PC boot, prompting you to press F1 or some other key to continue booting.

If you do not have a multimeter, you can take the battery with you to the store and ask them to check it or just buy a replacement battery in advance, it is standard and very inexpensive.

A clear sign of a dead battery is the constantly flying date and time on the computer.

The battery needs to be changed in a timely manner, but if you don’t have a replacement on hand now, then simply do not disconnect the system unit from the power supply until you change the battery. In this case, the settings should not fly off, but problems can still arise, so do not delay.

Checking the battery is a good time to completely reset the BIOS. This resets not only the BIOS settings, which can be done through the Setup menu, but also the so-called volatile CMOS memory, which stores the parameters of all devices (processor, memory, video card, etc.).

Errors inCMOSare often the cause of the following problems:

• computer does not turn on
• turns on once
• turns on and nothing happens
• turns on and off

I remind you that before resetting the BIOS, the system unit must be unplugged from the outlet, otherwise the CMOS will be powered by the PSU and nothing will work.

To reset the BIOS for 10 seconds, close the contacts in the battery connector with a screwdriver or other metal object, this is usually enough to discharge the capacitors and completely clear the CMOS.

A sign that the reset has occurred will be a lost date and time that will need to be set in the BIOS the next time the computer boots.

4. Visual inspection of components

Carefully inspect all capacitors on the motherboard for swelling and leakage, especially in the area of ​​\u200b\u200bthe processor socket.

Sometimes capacitors do not bulge up, but down, which causes them to tilt as if they were just slightly bent or unevenly soldered.

If some capacitors are swollen, then you need to send the motherboard for repair as soon as possible and ask to re-solder all the capacitors, including those that are next to the swollen ones.

Also inspect the capacitors and other elements of the power supply, there should be no swelling, drips, signs of burning.

Inspect the disc contacts for oxidation.

They can be cleaned with an eraser and after that it is imperative to replace the cable or power adapter with which this disk was connected, since it is already damaged and oxidation has most likely occurred due to it.

In general, check all the cables and connectors so that they are clean, with shiny contacts, tightly connected to the drives and the motherboard. All cables that do not meet these requirements must be replaced.

Check that the wires from the front of the case to the motherboard are connected correctly.

It is important that the polarity is observed (plus to plus, minus to minus), since there is a total mass on the front panel and non-observance of the polarity will lead to a short circuit, due to which the computer may behave inappropriately (turn on every other time, turn itself off or reboot) .

Where the plus and minus in the contacts of the front panel is indicated on the board itself, in the paper manual for it and in the electronic version of the manual on the manufacturer's website. On the wire contacts from the front panel, it is also indicated where the plus and minus are. Usually the white wire is negative, and the positive connector can be indicated by a triangle on the plastic connector.

Many even experienced builders make a mistake here, so check.

5. Checking the power supply

If the computer did not turn on at all before cleaning, then do not rush to assemble it, the first thing to do is check the power supply. However, in any case, it won’t hurt to check the PSU, maybe it’s because of it that the computer fails.

Check the power supply when fully assembled to avoid electric shock, short circuit, or accidental fan failure.

To check the power supply, short the only green wire in the motherboard connector with any black one. This will signal to the PSU that it is connected to the motherboard, otherwise it will not turn on.

Then turn the power supply into the surge protector and press the button on it. Do not forget that the power supply itself may also have an on / off button.

A spinning fan should be a sign of turning on the power supply. If the fan does not spin, then it may have failed and needs to be replaced.

In some silent power supplies, the fan may not start spinning immediately, but only under load, this is normal and can be checked during PC operation.

Use a multimeter to measure the voltage between the pins in the connectors for peripheral devices.

They should be approximately in the following range.

• 12 V (yellow-black) - 11.7-12.5 V
• 5 V (red-black) - 4.7-5.3 V
• 3.3 V (orange-black) - 3.1-3.5 V

If any voltage is missing or goes far beyond the specified limits, then the power supply is faulty. It is best to replace it with a new one, but if the computer itself is inexpensive, then repairs are allowed, PSUs lend themselves to this easily and inexpensively.

The start of the power supply and normal voltages is a good sign, but in itself it does not mean that the power supply is good, since failures can occur due to voltage drops or ripple under load. But this is already determined in the subsequent stages of testing.

6. Checking the power contacts

Be sure to check all electrical contacts from the outlet to the system unit. The socket must be modern (for a European plug), reliable and not loose, with clean elastic contacts. The same requirements apply to the surge protector and cable from the computer power supply.

Contact must be reliable, plugs and connectors must not dangle, spark or be oxidized. Pay close attention to this, as poor contact is often the cause of failure of the system unit, monitor, and other peripheral devices.

If you have a suspicion of a power outlet, surge protector, power cable for a system unit or monitor, then change them as soon as possible to avoid damaging your computer. Do not delay and do not skimp on this, as repairing a PC or monitor will cost significantly more.

Also, poor contact is often the cause of PC failures, which are accompanied by a sudden shutdown or reboot, followed by failures on the hard drive and, as a result, disruption of the operating system.

More failures can occur due to voltage drops or ripples in the 220 V network, especially in the private sector and remote areas of the city. In this case, failures can occur even when the computer is idle. Try to measure the voltage at the outlet immediately after a spontaneous shutdown or reboot of the computer and observe the readings for a while. So you can identify long-term drawdowns, from which a linear-interactive UPS with a stabilizer will save.

7. Assembling and turning on the computer

After cleaning and inspecting the PC, carefully assemble it and carefully check that you have connected everything you need. If the computer refused to turn on before cleaning or turned on every other time, then it is advisable to connect the components in turn. If there were no such problems, then skip the next section.

7.1. Step by step PC build

First, connect the motherboard power connector and the processor power connector to the motherboard with the processor. Do not insert RAM, video card and do not connect disks.

Turn on the power of the PC and if everything is fine with the motherboard, the CPU cooler fan should spin. Also, if a buzzer is connected to the motherboard, a beep code usually sounds, indicating the lack of RAM.

Memory installation

Turn off the computer with a short or (if not possible) long press of the power button on the system unit and insert one stick of RAM into the colored slot closest to the processor. If all slots are the same color, then just the one closest to the processor.

Make sure that the memory bar is inserted evenly, all the way and the latches snap into place, otherwise it may be damaged when you turn on the PC.

If the computer starts up with one memory bar and there is a beep, then a code usually sounds, signaling that there is no video card (if there is no integrated graphics). If the beep code indicates problems with the RAM, then try inserting another bar in the same place. If the problem continues or if there is no other bar, then move the bar to another nearest slot. If there are no sounds, then everything is probably fine, continue on.

Turn off the computer and insert the second stick of memory into the slot of the same color. If the motherboard has 4 slots of the same color, then follow the instructions for the motherboard so that the memory is in the slots recommended for dual-channel mode. Then turn it on again and check if the PC turns on and what beeps it makes.

If you have 3 or 4 sticks of memory, then just insert them in turn, each time turning off and on the PC. If the computer does not start with a certain bar or gives a memory error code, then this bar is faulty. You can also check the motherboard slots by rearranging the work bar in different slots.

Some motherboards have a red indicator that glows in case of memory problems, and sometimes a segment indicator with an error code, the decoding of which is in the motherboard manual.

If the computer starts, then further memory testing occurs at another stage.

Installing a graphics card

It's time to test the video card by inserting it into the top PCI-E x16 slot (or AGP for older PCs). Do not forget to connect additional power to the video card with the appropriate connectors.

With a video card, the computer should start normally, without beeps, or with a single beep, indicating a normal self-test.

If the PC does not turn on or emits a beep error code for the video card, then it is most likely defective. But do not rush to conclusions, sometimes you just need to connect a monitor and keyboard.

Monitor connection

Turn off the PC and connect the monitor to the video card (or motherboard if there is no video card). Make sure that the connector to the video card and the monitor is connected tightly, sometimes tight connectors do not go all the way, which is the reason for the lack of image on the screen.

Turn on the monitor and make sure that the correct signal source is selected on it (the connector to which the PC is connected, if there are several).

Turn on the computer and a graphic splash screen and motherboard text messages should appear on the screen. Usually this is a suggestion to enter the BIOS using the F1 key, a message about the absence of a keyboard or boot devices, this is normal.

If the computer turns on silently, but there is nothing on the screen, there is most likely something wrong with the video card or monitor. The video card can only be checked by moving it to a working computer. The monitor can be connected to another working PC or device (laptop, player, tuner, etc.). Do not forget to select the desired signal source in the monitor settings.

Keyboard and mouse connection

If everything is fine with the video card and monitor, then we move on. In turn, connect the keyboard first, then the mouse, each time turning off and on the PC. If the computer freezes after connecting the keyboard or mouse, then they need to be replaced - it happens!

Connecting Drives

If the computer starts with a keyboard and mouse, then we begin to connect hard drives in turn. Connect a second drive without an operating system (if any) first.

Do not forget that in addition to connecting the interface cable to the motherboard, you also need to connect the connector from the power supply to the disk.

Then turn on the computer and if it comes to BIOS messages, then everything is fine. If the PC does not turn on, freezes or turns off by itself, then the controller of this disk is out of order and needs to be changed or taken in for repair to save data.

Turn off the computer and connect the DVD drive (if any) with an interface cable and power supply. If after that problems arise, then the drive fails in power supply and needs to be changed, it usually does not make sense to repair.

At the end, we connect the main system disk and prepare to enter the BIOS for initial setup before starting the operating system. We turn on the computer and if everything is fine, proceed to the next step.

When you turn on your computer for the first time, enter the BIOS. Usually, the Delete key is used for this, less often others (F1, F2, F10 or Esc), which is indicated in the prompts at the beginning of the download.

On the first tab, set the date and time, and on the “Boot” tab, select your hard drive with the operating system as the first boot device.

On older motherboards with a classic BIOS, it might look like this.

On more modern ones with a graphical shell, UEFI is a little different, but the meaning is the same.

To exit the BIOS and save the settings, press F10. Do not get distracted and watch the operating system fully boot to notice possible problems.

After the PC has finished booting, check if the fans of the processor cooler, power supply and video card are working, otherwise it makes no sense to carry out further testing.

Some modern video cards may not turn on the fans until a certain temperature of the video chip is reached.

If any of the case fans are not working, then this is not a problem, just plan to replace it in the near future, do not be distracted by it now.

8. Error analysis

Here, in fact, diagnostics begin, and all of the above was only preparation, after which many problems could go away and without it it made no sense to start testing.

8.1. Enabling memory dumps

If blue screens of death (BSOD) appear during computer operation, this can greatly facilitate the identification of a malfunction. A prerequisite for this is the presence of memory dumps (or at least self-written error codes).

To check or enable the dump recording function, press the key combination "Win + R" on the keyboard, enter "sysdm.cpl" in the line that appears and press OK or Enter.

In the window that appears, go to the "Advanced" tab and in the "Startup and Recovery" section, click the "Options" button.

The "Write debug information" field should be "Small memory dump".

If so, then you should already have previous error dumps in the C:\Windows\Minidump folder.

If this option was not enabled, then dumps were not saved, enable it at least now to be able to analyze errors if they are repeated.

Memory dumps may not be able to be created during severe crashes such as rebooting or shutting down the PC. Also, some system cleaning utilities and antiviruses can remove them, you must disable the system cleaning function for the duration of the diagnosis.

If there are dumps in the specified folder, then proceed to their analysis.

8.2. Memory dump analysis

To analyze memory dumps in order to identify what causes failures, there is a wonderful BlueScreenView utility, which you, along with other diagnostic utilities, can download in the "" section.

This utility shows the files that have failed. These files belong to the operating system, device drivers or some program. Accordingly, by the ownership of the file, you can determine which device or software was the cause of the failure.

If you cannot boot your computer in normal mode, then try booting into safe mode by holding down the "F8" key immediately after the disappearance of the motherboard graphic splash screen or BIOS text messages.

Go through the dumps and see which files appear most often as the culprits of the crash, they are highlighted in red. Right-click on one of these files and view its Properties.

In our case, it is easy to determine that the file belongs to the nVidia video card driver and most of the errors were caused by it.

In addition, in some dumps, the file "dxgkrnl.sys" appeared, even from the name of which it is clear that it refers to DirectX, which is directly related to 3D graphics. So, it is most likely that the video card is to blame for the failure, which should be subjected to thorough testing, which we will also consider.

In the same way, you can determine that the cause of the failure is a sound card, network card, hard drive, or some kind of program that gets deep into the system such as an antivirus. For example, if a disk fails, the controller driver will crash.

If you cannot determine which driver or program a particular file belongs to, then look for this information on the Internet by the name of the file.

If failures occur in the sound card driver, then most likely it is out of order. If it is integrated, then you can disable it through the BIOS and install another discrete one. The same can be said about the network card. However, network failures can be caused, which often resolves by updating the network card driver and connecting to the internet through a router.

In any case, do not make hasty conclusions until the diagnostics are completed, maybe your Windows just crashes or a virus has climbed, which is solved by reinstalling the system.

Also in the BlueScreenView utility, you can see the error codes and inscriptions that were on the blue screen. To do this, go to the "Options" menu and select the "Blue Screen in XP Style" view or press the "F8" key.

After that, switching between errors, you will see how they looked on the blue screen.

By the error code, you can also find a possible cause of the problem on the Internet, but it is easier and more reliable to do this by file ownership. You can use the F6 key to return to the previous view.

If different files and different error codes appear in errors all the time, then this is a sign of possible problems with RAM, in which everything crashes. We will diagnose it first of all.

9. Testing RAM

Even if you think that the problem is not in the RAM, still check it first. Sometimes a place has several problems, and if the RAM fails, then diagnosing everything else is quite difficult due to frequent PC failures.

Running a memory test from a boot disk is a must, as it is difficult to get accurate results on a Windows operating system on a failed PC.

In addition, "Hiren's BootCD" contains several alternative memory tests in case "Memtest 86+" does not start and many more useful utilities for testing hard drives, video memory, etc.

You can download the "Hiren's BootCD" image in the same place as everything else - in the "" section. If you do not know how to burn such an image to a CD or DVD, refer to the article where we reviewed, everything is done in the same way.

Set BIOS to boot from DVD drive or use Boot Menu as described in , boot from Hiren's BootCD and run Memtest 86+.

Testing can last from 30 to 60 minutes, depending on the speed and amount of RAM. One full pass should be completed and the test will go for the second round. If everything is fine with the memory, then after the first pass (Pass 1) there should be no errors (Errors 0).

After that, testing can be interrupted using the "Esc" key and the computer will restart.

If there were errors, then you will have to test each bar separately, taking out all the others to determine which one is broken.

If the broken bar is still under warranty, then take a photo from the screen using a camera or smartphone and present it to the warranty department of the store or service center (although in most cases this is not necessary).

In any case, it is not advisable to use a PC with a broken memory and carry out further diagnostics before replacing it, as various incomprehensible errors will pour in.

10. Preparation for component tests

Everything else, except for RAM, is tested from under Windows. Therefore, in order to exclude the influence of the operating system on the test results, it is advisable to do, if necessary, temporarily and most.

If this is difficult for you or there is no time, then you can try testing on the old system. But, if failures occur due to malfunctions in the operating system, some kind of driver, program, virus, antivirus (i.e., in the software part), then testing the hardware will not help determine this and you may go the wrong way. And on a clean system, you will have the opportunity to see how the computer behaves and completely eliminate the influence of the software component.

Personally, I always do everything right from start to finish as described in this article. Yes, it takes a whole day, but neglecting my advice, you can fight for weeks without determining the cause of the problem.

The fastest and easiest way is to test the processor, unless of course there are obvious signs that the problem is, say, in the video card, which we will discuss below.

If your computer, after some time after turning on, starts to slow down, freezes when watching videos, in games, suddenly reboots or turns off under load, then there is a possibility of overheating of the processor. In fact, this is one of the most common causes of such problems.

At the stage of cleaning and visual inspection, you should have made sure that the CPU cooler is not clogged with dust, its fan rotates, and the heatsink is firmly pressed against the processor. I also hope you didn't take it off when you cleaned it, as that requires replacing the thermal paste, which I'll talk about later.

We will use "CPU-Z" for the stress test with the processor warming up, and "HWiNFO" for monitoring its temperature. Although it is better to use the proprietary utility of the motherboard to monitor the temperature, it is more accurate. For example, ASUS has "PC Probe".

To begin with, it would be nice to know the maximum allowable thermal package of your processor (T CASE). For example, for my Core i7-6700K it is 64°C.

You can find out by going to the manufacturer's website from an Internet search. This is the critical temperature in the heat spreader (under the processor cover), the maximum allowed by the manufacturer. Don't confuse it with the temperature of the cores, which is usually higher and is also displayed in some utilities. Therefore, we will focus not on the temperature of the cores according to the processor sensors, but on the overall temperature of the processor according to the readings of the motherboard.

In practice, for most older processors, the critical temperature above which failures begin is 60 °C. The most modern processors can work at 70 ° C, which is also critical for them. You can find out the real stable temperature of your processor from tests on the Internet.

So, we launch both utilities - “CPU-Z” and “HWiNFO”, find the processor (CPU) temperature sensor in the motherboard indicators, run the test in “CPU-Z” with the “Stress CPU” button and monitor the temperature.

If after 10-15 minutes of the test the temperature is 2-3 degrees lower than the critical one for your processor, then there is nothing to worry about. But, if there were failures under high load, then it is better to run this test for 30-60 minutes. If during testing the PC freezes or reboots, then you should think about improving the cooling.

Keep in mind that a lot also depends on the temperature in the room, it is possible that in cooler conditions the problem will not manifest itself, but in hotter conditions it will immediately make itself felt. So you always need cooling with a margin.

In case of CPU overheating, check if your cooler complies with . If not, then you need to change it, no tricks will help here. If the cooler is powerful enough, but can't cope a little, then you should change the thermal paste for a more efficient one, and at the same time the cooler itself may be installed more successfully.

From inexpensive, but very good thermal pastes, I can recommend Artic MX-4.

It should be applied in a thin layer, after removing the old paste dry and then with cotton wool soaked in alcohol.

Replacing thermal paste will give you a gain of 3-5 ° C, if this is not enough, then simply install case fans, at least the most inexpensive ones.

14. Drive testing

This is the longest stage after the RAM test, so I prefer to leave it for last. To begin with, you can test the speed of all disks using the HDTune utility, to which I give "". This sometimes helps to identify freezes when accessing the disk, which indicates problems with it.

Look at the SMART options, where "disk health" is displayed, there should be no red lines and the overall status of the disk should be "OK".

You can download the list of the main SMART parameters and what they are responsible for in the "" section.

A full surface test can be performed using the same utilities from under Windows. The process can take 2-4 hours depending on the size and speed of the disk (about 1 hour for every 500 MB). At the end of the test, there should not be a single broken block, which is highlighted in red.

The presence of such a block is an unequivocal verdict for the disk and a 100% guarantee case. Save your data faster and change the drive, just don't tell the service that you dropped your laptop

You can check the surface of both conventional hard drives (HDD) and solid state drives (SSD). The latter really do not have any surface, but if the HDD or SSD drive freezes every time during the check, then the electronics most likely fail - you need to change or repair (the latter is unlikely).

If you are unable to diagnose the disk from under Windows, the computer crashes or freezes, then try to do this using the MHDD utility from the Hiren's BootCD boot disk.

Problems with the controller (electronics) and the disk surface lead to windows with errors in the operating system, short-term and complete freezes of the computer. Usually these are messages about the impossibility to read a particular file and memory access errors.

Such errors can be mistaken for problems with the RAM, while the disk may well be to blame. Before you panic, try updating the disk controller driver, or vice versa, return the native Windows driver as described in.

15. Testing the optical drive

To check an optical drive, it is usually enough to simply burn a verification disc. For example, using the Astroburn program, it is in the "" section.

After burning a disc with a message about successful verification, try to completely copy its contents on another computer. If the disc is readable and the drive reads other discs (except for poorly readable ones), then everything is fine.

Drive problems I've encountered include electronic failures that completely hung up or prevented the computer from turning on, breakage of the retractable mechanism, contamination of the laser head lens, and breakage of the head as a result of improper cleaning. In most cases, everything is solved by replacing the drive, since they are inexpensive and even if they have not been used for several years, they die from dust.

16. Hull check

The case also sometimes breaks, then the button sticks, then the wiring from the front panel falls off, then it closes in the USB connector. All this can lead to unpredictable behavior of the PC and is solved by a thorough inspection, cleaning, tester, soldering iron and other improvised means.

The main thing is that nothing is short, which may be indicated by a broken light bulb or connector. If in doubt, disconnect all wires from the front of the case and try to work at the computer for a while.

17. Checking the motherboard

Often, checking the motherboard comes down to checking all the components. If all the components individually work fine and pass the tests, the operating system is reinstalled, but the computer still crashes, it may be the motherboard. And here I won’t help you, only an experienced electronics engineer can diagnose it and identify a problem with a chipset or processor socket.

The exception is the crash of a sound or network card, which is solved by disabling them in the BIOS and installing separate expansion cards. You can solder the capacitors in the motherboard, but let's say replacing the north bridge is usually not advisable, since it is expensive and there are no guarantees, it is better to immediately buy a new motherboard.

18. If nothing helps

Of course, it's always better to find the problem yourself and determine the best way to solve it, as some unscrupulous repairmen strive to hang noodles on your ears and tear off three skins.

But it may be that you follow all the recommendations, but you will not be able to determine the problem, it happened to me. In this case, the matter is more often in the motherboard or in the power supply, maybe there is a microcrack in the textolite and it makes itself felt from time to time.

In this case, nothing can be done, bring the entire system unit to a more or less well-established computer company. No need to wear parts in parts, if you are not sure what the matter is, then the issue will never be resolved. Let them figure it out, especially if the computer is still under warranty.

Computer store specialists usually do not worry, they have a lot of different components, they just change something and see if the problem is gone, thus fixing the problem quickly and simply. They also have enough time to conduct tests.

1. Quite a lot of questions are asked by people of a similar nature as described above. There are quite a few answers to such questions, here are two common answers, so to speak:
2. You can download programs to test the processor, RAM, hard drive, video card, there are many such programs. At the very bottom I will offer you links for downloading such programs from official sites.
3. There is another simple solution, these are specially written programs for just such purposes. They have both a general test for the entire computer device at once, and tests separately for each hardware.
4. A method without programs in which you need a Windows notepad and write a few lines in it. Then rename the extension and run it for execution.

Acquaintance, history, AIDA64.

5. I'll start with the best option in my opinion, everyone has their own, otherwise we would be bots, there is of course that people are of the same opinion, but not in everything! Here is what is written about this program in the Wiki, not much accompaniment from history:
6. ASMDEMO (1995) - the first version of a program capable of detecting and diagnosing PC components, was written by Tamas Miklos in assembler and partly in pascal. In 1996, the first public release of ASMDEMO v870 was released, including a CPU and HDD benchmark.
7. AIDA (2000) - Hardware database contains 12,000 entries with MMX and SSE support. Later, with the expansion of capabilities, the program was renamed AIDA16, but everything also had a text interface.
8. AIDA32 (2001) - written in Delphi, the program began to use a graphical interface. Version 2.00 was released in 2002, supporting XML report and SQL database. Version 3.61, introduced in 2003, had a hardware database of 25,000 entries, monitoring, and support for 23 languages. The latest version 3.94.2 was released in March 2004.
9. Everest (2004) - the program becomes commercial and is being developed by Lavalys. Version 3.00, released in 2006, contains a 44,000-entry hardware database, graphical remote control, and a system stability test. The latest version 5.50 was introduced in April 2010.
10. AIDA64 (2010) - The rights to the program are acquired by FinalWire. The hardware database contains 115,000 entries with 64-bit and SSD support. Version 2.00, which appeared in October 2011, received the ability to automatically update, and the database increased to 133,000 records. The latest version 5.95, released in November 2017, has a hardware database of 170,000 entries.
11. The program is really worthwhile and what is most important is that it is written in Delphi - it is a logical programming language. If you are good with technical English and you know how to think logically, this language will definitely suit you. I started writing on it at the age of 18, and now I'm already 40. The language is simple and now it is developing and its name has changed to but delphi is also there. You can write programs for Windows, Android, Mac, of course there is a version for LINUX. Many components have already been written and they just need to be made to work and be friends with each other. It seemed to me an interesting lesson and I got hooked on this language for a long time. But this article is not about that, but how can you still load your computer and find out what will soon fail or is not stable?

Stress test Aida 64 Extreme

12. After downloading the program, it is paid, but there is a test period and it is enough to find out if we need to do a stress test of our computer assistant and thereby find out the answer to the questions above. The program is available not only for users but, of course, there is a version for you can also test it. And since this is not the only function of the program, there are a lot of useful things in it if you want to know as much as possible about your device, you can even compare it with other devices in the table, which is also in the program. Why am I writing everything, it is necessary to show how it all looks and, using an example, we will launch the stress test of your computer assistant as promised. 30 days of the trial period, as I wrote above, is enough to test your computer to death, just kidding!
13. After installing and running Aida64Extreme, I chose this version and a window about the test period appeared, which we close by clicking on the "OK" button and go to the program interface. At the very top of the program there is the name of the menu "Service" and we need it. Having opened the menu, it will contain the tests we need. As I wrote above, I mentioned that you can test separately or immediately, I think to show an example on the system stability test. This quiz fits the article and the questions exactly.
14. Having opened the "System Stability" test, you need to choose what we will test, all at once or separately, here judge for yourself as you please. I'll take everything to test at once and then I'll see how the test passed, what's new in my computer happened over a long time of work. But I will tell you the description of the tests separately, for those who want to test separately or need to test only one piece of computer hardware. See the description of the tests below, there are 6 of them in total:
15. 1.) Stress CPU - CPU Test
16. 2.) Stress FPU - This is a Floating Point Unit - a block that performs floating point operations, is located in the processor and will give an additional load, which is what we need.
17. 3.) Stress Cache - Test processor cache.
18. 4.) Stress System Memory - RAM test.
19. 5.) Stress Local Disk - Test hard drive, write, read, copy and so on.
20. 6.) Stress GPU(s) - A test of the GPU, or rather the video card, let's say so that it is more understandable. If you have a laptop with two cards, then all video processors will be loaded.
21. Check all the checkboxes and click the "Start" button in the lower left corner. We leave the computer for several hours and if during this time your PC or laptop did not give any errors, it may have rebooted or turned off. Then in 99% of cases everything is fine with him and your electronic assistant will still serve you! If there were some actions that were described above, then it is necessary to proceed from them and move on because of what happened, let's say, rebooting the PC? Here, the temperature may have jumped, by the way, the temperature must be observed during the test. It is shown in the same window where there are checkboxes with tests. The topmost green rectangle with charts. Which show the temperature of the motherboard, processor and hard drive.
22. Actually, we sometimes start observing and leave for an hour or longer, also as you wish or as you see fit. But of course, you need to test for at least half an hour, I personally think so, otherwise little will be clear from such a quick test. With the help of the program, you can also go to the official sites for your hardware or also from the official sites of manufacturers. These links can be found in the description of the selected piece of iron (accessory).

Stress test program OCCT - OverClock Checking Tool.

23. unlike AIDA64, it differs in that it does not contain information about the system, let's say such extended ones. There is information, but there are few of them, and only about the most important thing about the processor and, in principle, everything, superficially, you can see for yourself by looking at the screen below. But it was only written for a stress test, I launched it and forgot it for several hours, I first chose which test or completely tested everything, I wrote about such methods above and not a little. Having launched the program, it will consist of two windows, in the left one there will be a choice of test and settings, and in the right window there will be information on voltage and temperature.
24. In the left window there will be four tabs, on which, if you navigate through them, there will be settings for various tests.
25. 1.) CPU OCCT - Test of CPU only, or CPU and memory, CPU + memory + chipset. Three choices are obtained as to how this test can be run.
26. 2.) CPU LINPACK - CPU only test.
27. 3.) GPU 3D - Video card test.
28. 4.) POWER SUPPLY - testing the batteries of the motherboard, power supply, power load test, let's say so.
29. There are three buttons on each tab: ON- Run the test. OFF- Stop the test. The general setting, let's say, is the third gear button.
30. By pressing the gear button, setting, you can set the temperature, which is very good in such tests. If the testing programs do not stop the test if the temperature is higher than the specified one, then the computer will turn itself off or reboot. If there is such a setting, then we set it a little less than it should be in the settings of the computer and the test will be stopped if the temperature rises. The picture is below and the setting is set if the temperature of the GPU - video card is above 85 s, then stop the test. It is worth setting this setting, it is very convenient.
31. Now let's go through the test settings and see what you can set:
33. CPU: OCCT is the first tab, and as the description for the tests above wrote, there are three options for choosing, processor, memory, chipset, in fact, there is a choice. Let's start from the beginning and the first thing we see on this tab, if we start from the top, is the type of testing. There are two options for testing - auto and endless, set auto to adhere to the general temperature settings that I wrote about above.
34. Test duration - I think everything is clear here, how long to test.
35. The period of inactivity - this is necessary for the program to write data, save, read, and so on, leave it as it is by default.
36. Test version - What system and processor do you have, if it supports 64 bits, then we set it as it is.
37. Test mode - Here are these three options to choose from, which test to choose. Small data set - we test one processor. Medium - processor, memory. Large - processor, memory, chipset.
38. Number of threads - how many cores are in your processor.

We are done with the first tab and move on to the second tab and the CPU LINPACK test.

40. Setting up this test is simple and if you look at the first test, everything is basically the same and you can understand how to set the settings, if it’s not clear, write in a comment or read more carefully about the first test (tab).

GPU 3D - Video card test, third tab in a row.

41. There is something to talk about here, though we have already discussed the first three settings in the first test. Let's start with the fourth setting - DirectX, set which one your electronic assistant has or which one your video card supports. To find out what is in the system, you can type the name of the file "dxdiag" in the computer search and run it. In general, it is located in the Windows\system32 folder.
43. Next comes the name of your video card, the model of the video card, you can see or compare in the device manager in Windows.

POWER SUPPLY - fourth tab.

48. I said above that this is a test of the power supply and, in fact, this test is not for a simple computer user. But if you want to pass it, then set the values, look at the tests above, everything is the same. Voltage will be applied to all pieces of iron, components of a computer device immediately and maximum. Maybe if the power supply is cheap, it can't handle the load. I repeat that all the settings on this test were also described in other tests, just compare by name.
50. After setting up each of the tests, press the "on" button or if you want to stop the test without waiting for the end of "off". If you have any questions, comment below, write the answer.

How to do a processor test without programs?

51. For such a test, we need a notepad and a program manager. The notepad is not the one that is paper, but the one that is installed in the system by default, you can use others at your discretion, say notepad. In notepad, enter two lines for Visual Basic:

while True

Wend

52. We save the file under any name, but the file extension is what comes after the dot, it should not be txt, as it should be in notepad, but vbs. We saved the dct file and go to the "task manager", you can open it by clicking on the "pkm" taskbar. Then select "Task Manager" from the context menu
54. In the task manager, open the "Performance" tab on which there is a display of computer and processor load, it also shows. We need a processor, since we will load it with a task, many core processors in the "Task Manager" do not always display all the cores, only the total load of the "Processor" is shown. If this is enough for you, then we leave it as it is and we will observe from here if you want to see information separately for each core. Then we go further and open the "Resource Monitor", at the very bottom in the Task Manager on the same tab "Performance" there is a hyperlink "Open Resource Monitor", see the picture below:
55. Having opened the resource monitor, the "CPU" tab is the second in a row, the processor load will immediately be shown for each core.
56. Now we launch the previously created file by clicking on it with the mouse, you may have to launch more than one copy of the previously created file by clicking several times with the mouse. We look in the resource monitor how the processor is loaded, leaving it for several hours, you can find out if there are errors during execution. To stop this task, you need to go to the "task manager" and on the "processes" tab, it is the first one to find the name of the file with the VBS extension. By right-clicking on the name in the list of processes, in the drop-down list, click "End task". So the execution of the processor load will be stopped.
