Testing motherboard. Setting up BIOS settings

A television

With the output of the processors of the 7th generation and system logic for the CPU data, Intel has tightened its attitude towards lovers of "free MHz", i.e. Overclockers by blocking the possibility of overclocking processors with the index "K" and without it, for all chipsets, except for the top Intel Z270 Express. Therefore, if you want to collect a powerful computer with an overclocked processor, you need to choose a motherboard on the older chipset.

We have already met with a lot of interesting motherboards from Gigabyte, each of which is unique in its own way and has interesting features. We considered GA-Z270X-Gaming 5, GA-Z270X-Gaming 7 and GA-Z270X-Gaming K3 are located in the upper and middle price range, ranging from 9000 rubles. and higher. And what to do those who do not want to spend a big amount on the motherboard, but at the same time want to get a maximum of opportunities from it?
In this case, you need to pay attention to budget cards, such as Gigabyte GA-Z270-HD3, which can be found in the Russian retail at a price of 7500 rubles. (According to Yandex.Market, the cost may vary depending on the region and date).
At first glance, it may seem that Gigabyte GA-Z270-HD3 is too simple or overclocking can be forgotten, but this is not the case, and, after reading this review to the end, you will be sure of it.

Packaging and equipment.

The GA-Z270-HD3 motherboard comes in a small, modern standards, a cardboard box with an interesting design. A large UD5 logo is encountered in front (Ultra Durable 5), which is a kind of quality mark. In the Gigabyte motherboards made as part of the Ultra Durable concept, high-quality components are used that guarantee the stable operation of the processor, RAM modules and the system as a whole throughout the life of the product.
On the opposite side, we see the technical characteristics of the GA-Z270-HD3 and its description of its capabilities. Despite the price, the motherboard received many useful technologies in his arsenal. For example, Smart Fan 5 - allows the user in real time to monitor the working temperature of the motherboard, thanks to 6 temperature sensors, and customize the operation of the fans.
Inside the box, the board is laid in a cardboard tray and packed in an anti-static package.

In the set of delivery we found:
- user's manual;
- disk with software;
- 2 x SATA cable;
- plug for the interface panel;
- G-connector.

Appearance.

The GA-Z270-HD3 motherboard is based on a brown textolite. The fee relates to the form factor ATX, but in reality its size is slightly less - 305 x 225 mm. It is not necessary to wait for the GA-Z270-HD3 of the design of the GA-Z270-HD3, after all, it is the fee of the entry level, but, even despite this, it looks quite modern.

The wiring of the motherboard is quite standard, operational memory slots and the top slot PCIe 3.0 x16 are located at sufficient removal from each other, so that you do not have to remove the RAM to replace the RAM modules from the system unit.
The opposite side of the printed circuit board looks standard, the only thing that can be noted here is plastic clips for fastening radiators, which in practice turned out to be very reliable.

Four slots are intended for RAM. GA-Z270-HD3 supports modules with a frequency of up to 3866 MHz and a total volume of up to 64 GB (4 x 16 GB).
Full list of supported frequencies looks like this: DDR4 3866 (OC) / 3800 (OC) / 3733 (OC) / 3666 (OC) / 3600 (OC) / 3466 (OC) / 3400 (OC) / 3333 (OC) / 3300 (OC) / 3200 (OC) / 3000 (OC) / 2800 (OC) / 2666 (OC) / 2400 (OC) / 2133 MHz.
In the neighborhood of DIMM slots, two pads for additional USB3.0 ports can be connected to 4 ports in sum.

PCB is planted with six slots to install the extension boards:
- 1 x PCIe 3.0 x16 (x16 mode);
- 2 x PCIe 3.0 x16 (x4 and x4 mode);
- 2 x PCIe 3.0 x1;
- 1 x PCI.

For hard drives and SSD drives, four SATA ports 6 Gbps and one SATA Express are provided. The latter, if you do not have compatible device interface, you can use as a pair of regular SATA ports.

More high-speed SSD drives can be installed in the port M.2, which supports the following sizes: 2242/2260 / 2280 / 22110. The drive can be organized as in PCIe 3.0 x4 mode and in SATA mode.

At the bottom of the PCB, there is a large set of pads for connecting peripheral interfaces: F_Audio, COM, LPT, TPM, 2 x USB2.0, F_PANEL.

The following connectors are presented on the interface panel:
- 1 x DVI-D;
- 1 x D-sub;
- 1 x HDMI;
- 1 x PS / 2;
- 1 x LAN RJ45;
- 4 x USB 3.1;
- 2 x USB 2.0;
- 6 x audioorts.

The sound subsystem GIGABYTE GA-Z270-HD3 is based on the 8-channel HD-audio code for REALTEK ALC887, and part of the printed circuit board on which it is located is isolated from the rest of the board. Also in the sound tract used high-quality Japanese audio addicts.

The motherboard cooling system consists of two aluminum radiators, one cools the chipset, and the second takes the heat from the CPU power module. Despite the compact sizes of radiators, they cope well with their task, the temperature of the hottest of them was only 35 degrees!

The CPU power module has at its disposal seven phases organized according to the 4 + 3 phase scheme. Four phases are highlighted for powering the processor nuclei, they are cooled with a radiator, and three more phases are highlighted to power the built-in graphics core. The elementary base of the nutrition system is typed from high-quality components, solid-state capacitors and chokes with a ferrite core.

The VRM module controls the Intersil 95866 controller.

Gigabyte GA-Z270-HD3 motherboard, despite its external simplicity, has an informative graphic shell, which boasts a spectacular and intuitive user interface. The possibilities of bios, in terms of overclocking and system settings, no longer inferior to more expensive devices. In Easymode mode on the main page there are ten blocks, with information about:
- processor temperature;
- system components;
- the temperature of the motherboard and Vcore voltage;
- speed of rotation of the connected fans;
- Connected SSD and HDD drives.

In Advanced mode, which has an extended functionality, we get to the page M.i.t. It contains many parameters required for overclocking and simply system settings. Here all parameters are concentrated here, it is necessary to overclock the processor and RAM: CPU multiplier, BCLK frequency, memory frequency, power system settings, timing settings and the ability to increase stresses. In addition, there is a separate submenu of the processor power system setting.

Advanced Frequency Setting is responsible for setting up: Processor multiplier, BCLK bus frequency, RAM frequencies, Northern bridge frequencies, Frequency of the built-in graphics core.

Advanced Memory Setting are settings associated with RAM, XMP profile activation function, timing settings and subittime.

Advanced Voltage Setting allows you to configure the main operating stresses that you need to overclock: vcore, vmem, etc. Here you can configure the operation of the processor and RAM power supply system.

The SYSTEM tab contains time and date settings, as well as the language selection function, by the way, the BIOS is translated into Russian, so if you don't care with English, you can still easily navigate in the BIOS.

The BIOS tab contains information about the computer loading mode.

In Peripherals, you can disable or enable controllers you need, for example, LAN controller.

Audio codec and integrated graphics is configured in Chipset.

The POWER tab will allow you to configure the power on the PC when you press the mouse button or the keyboard key.

The Save & EXite tab is understandable for what is needed.

Overview of the corporate software.

Included with the motherboard there is a disc with all Gigabyte brand software, you can also download it from the company's official website. Let's start with the simplest CPU-Z program, the design of which has been changed in favor of the manufacturer's corporate style.

Next, the list of App Center is underway - this is a basic program, you can even say the basis that you can supplement the functions for you. All installed programs from Gigabyte will automatically come here, and get rid of you from dozens of shortcuts on the desktop.

Here, several tabs, such as Advanced CPU OC, contains the settings responsible for the processor acceleration. Moreover, here you can control not only frequencies, but also voltages, which greatly simplifies and speeds up the process of overclocking and search for stable frequencies. As you can see, the Gigabyte GA-Z270-HD3 did not exception and received exactly the same capabilities on setting up as more expensive fees.

Advanced DDR OC contains memory settings, including timings.

The CPU power management is presented in the Advanced Power tab.

In HotKey, you can configure hot keys to save profiles with your selected settings.

The next program in the queue has become Ambient LED, in which you can configure the operation of the LED backlight. In the case of our fees under consideration, only two modes (static glow and pulsating) are available to change.

System Information Viewer - a program that allows you to configure the operation of the computer cooling system, or rather the fans connected to the motherboard. The first tab provides information about the system.

Next, on the Smart Fan 5 tab, the program proposes to choose one of the pre-prepared profiles: Quiet, Standard, Perfomance, Full Speed. Modes are set up ascending, the most quiet - quiet, and the most productive - Full Speed. The most optimal noise / performance ratio, in our opinion, has Standard, although it will depend on the type of fans installed in your PC.

Going to Smart Fan 5 Advanced you can configure the operation of each connected fan, manually setting the rotational speed depending on the temperature of the components.

In the RECORD tab, you can activate the monitoring of the main parameters of the system and save the data into a separate file.

3D OSD is a program that is fully intended for monitoring computer parameters. In addition to the fact that it can follow the status of a computer, it can and output the user-needed information on the monitor screen, over all windows.

Testing.

Test stand:
- Intel Core i5-7600K processor
- CO: Corsair H110i GTX
- RAM KFA2 Hall of Fame DDR4-3600 2 x 8 GB
- Corsair Ax1200i
- Video card RADEON R9 280X.

Testing was carried out in two stages: Initially, test applications were held at nominal frequencies, and then the same applications were held at elevated frequencies in overclocking mode.

Nominal system settings.

Settings in overclocking mode.
On the Gigabyte GA-Z270-HD3 motherboard, we managed to dispersed the processor to a frequency of 5000 MHz, while it kept full stability in all benchmarks. To do this, we had to increase the stress on the core to 1.315 V.
For the convenience of perception, all test results in benchmarks are given as graphs.

Less - better

More - better

Less - better

During testing, using a thermometer, we measured the operating temperatures to which the cooling system radiators are heated. The radiator of the power system in a simple warmed up to a temperature of 34 ° C.

The Intel Z270 Express chipset radiator warmed up to 35 ° C.
Below on schedules, we give all the temperature values \u200b\u200bthat we measure when testing.

Conclusion.
Gigabyte GA-Z270-HD3 will be a great base for a home computer. The motherboard will easily provide a stable operation of modern Core i5 or Core i7 processors even in overclocked state. A computer collected on Gigabyte GA-Z270-HD3 will be able to solve a wide range of tasks, starting with work or surfing on the Internet, and ending with modern games.
Honestly, the first time to see this fee, we did not expect anything outstanding from her, not to mention the acceleration of the processor to 5 GHz. However, after a detailed acquaintance, these thoughts immediately disappeared.
Yes, Gigabyte GA-Z270-HD3 looks much easier than more expensive solutions, but it does not deteriorate its performance from this one of the parameters. What was clearly demonstrated in the Testing section.
Do not forget about the possibilities of expansion, the GA-Z270-HD3 has everything in order, in addition to the additional USB ports, the 2nd and 3rd generations, you can connect to it with the COM and TPM interface, which may be relevant For office tasks.
Perhaps someone from users the design of the device may seem too simple, however, if you do not use the computer at home in the form of an open stand, it will not be a problem. A steep design lovers need to pay attention to a more expensive price segment, such as the AORUS line.
Therefore, according to the testing of the motherboard Gigabyte GA-Z270-HD3, we can say the following. GA-Z270-HD3 will be a good choice for assembling a PC with a limited budget and desire to further disperse the processor so that, if necessary, increase computer performance.

Test inspection:

How to check your motherboard for performance? Connect to it BP (power supply) and start the map.

Should appear blue (green / red) LED indicator, notifying about the operating condition of the device.

By the way, the motherboard of the old sample is not so easy to run it, because there is no power button, as such.

You need to close the contacts.

If you are confident in the power supply, but the indicator is still lifeless, and the processor is intact and imbued, it means the case in the board.

We proceed to visual inspection and are looking for anything from the following:

scratches on textolite;

swollen capacitors;

extra pieces of metal;

curved or broken connectors;

dust;

bIOS battery.

Any scratch fee can cause irreparable damage to the system, since the tracks with contacts are divorced throughout the surface.

Motherboard and have a thickness with human hair, if not even thinner.

Be extremely neat when examining the board.

Swimming "Condes" - screaming a sign of a malfunction.

Thoroughly inspect everyone and if you find incapacitated - carry the product to the service center.

Is it possible to replace yourself and you have relevant knowledge?

Then go to the radio car and buy a detail with the same labeling, no analogues.

And yes, a tangible guarantee such a procedure will not give, extinguishing life motherboard For a year - another, but in the field you need to save what you have.

Metal can close the thinnest and invisible tracks, in contact with them.

Carefully blow the surface of the textolite, additionally walking with a brush from a natural pile.

No synthetics - it is static! Additionally, clean from dust.

And key attention is paid to the contacts that are closer to each other, forming a jumper, or simply twisted.

As an example, an Intel's socket connector is shown, but by analogy, it can be understood that it should not be.

By the way, most often "suffer" the contacts to which the system unit indicators are connected: LED-indicator of the inclusion, powered by external USB, various label light bulbs and all other. Be careful.

South and North Bridge on the motherboard

How to check the processor for performance

BIOS errors:

It would seem that, how to check the motherboard for errorsUsing this chip?

And it is responsible for all the basic settings of your computer and if the BIOS will fail, it will save only its complete replacement. But we will not be so pessimistic.

To begin with, change the battery of the device to the new one. It has a CR2032 labeling and sold in any household electronics store.

It is difficult to notice it on the motherboard, however, look around the PCI-EX X16 connector.

Turn off the power supply and very carefully remove the battery at 2-3 minutes so that all the settings finally dropped to factory, including the date and time.

Why do you need it?

Some "Kulibins" could, not realizing themselves, to recall something in the system, or "dispersed" components to a critical value.

BIOS is in defense and fully blocks the computer operation. This is such a good manipulation with the battery returns the factory type of product.

But not the fact that everything will turn out.

If it did not help, then we turn off the entire peripherals from the motherboard, leaving only a processor with a cooler and an inner speaker that "beats" at startup.

Inserted into the connector, next to which "SPK" or "SPKR" is written. Located next to the LED-indicators of the system unit.

The future of your motherboard will depend on it.

When the system starts, the sound of the RAM fault will appear.

If you hear it, it means that the motherboard is increasingly less in order. But if the silence is dead, then the hike to the service is not avoided.

No signal on the monitor when you turn on the computer

Table of sounds that inform about the problem of motherboard malfunction:

In total, there are 3 types of BIOS, each of which is endowed with its own logic.

What you have, you can learn on the labeling of the motherboard.

Sounds for each following:

Table of BIOS sounds - speaker notifying about AMI motherboard malfunction:

The BIOS Speaker Speaker Table, notifying about the Award Motherboard Problem:

The procedure for further action:

So there is sound.

Turn off the motherboard, and the first thing inserts one RAM plate (RAM).

We start re-listening.

In case of success, we are waiting for a video card fault warning (see the nameplate with sounds and their sequence).

We connect the video adapter and, if required, additional power. Additionally, connect the monitor to output the visual signal.

Turn on the computer and wait for the speaker signal.

If it is single and short, then everything is in order with your car. The reason was the dust, metal chips or the belt contact, which was returned to the original shape. This is if the capacitors are all right.

But if the sound of the video card does not disappear anywhere, it means it is to blame.

Otherwise, it is necessary to search for sound adapters, hard drives and other connected periphery.

How to check the hard disk performance

Results:

Do not hurry to bury motherboard at first opportunity.

Carefully inspect the device, guided by the instruction, then start alternately and in a certain sequence to cut off the "tailings" in the form of the entire additional installed equipment until it is stumbled upon the cause of all troubles.

You will succeed.

If a computer or laptop started working unstable, that is, the emergence of blue "death screens", errors that signal about some problems, have problems with the loading of the system, up to the complete absence of its signs of life, the motherboard malfunction may become the reason for this. . In this situation, you can attribute a computer to a service center, where the diagnostics of the computer will cost you money or try to test the motherboard yourself. But how to check the working capacity of the motherboard at home, if there is no specialized equipment, the necessary skills and knowledge? It is about this that we will talk further.

Checking the health of the motherboard - the beginning

The diagnosis of motherboard, as well as any other electronic device, begins with an external inspection and only after it, provided that there are no visible signs of damage, proceed to the following tests.

To do this, remove the left cover of the computer's system block to access MATEN. Next, we look at it for obvious defects.

First, you need to pay attention to the state of electrolytic capacitors. They should not be swollen, otherwise it may be the cause of a complete or partial system board malfunction.

Secondly, we inspect other electrical elements (resistors, chips, etc.) on the absence of signs of burnout. As a rule, the temperature effects, due to the increased load, voltage or short circuit jumps, leads to their failure, followed by a change in their color. They become darker, and the inscriptions on them, if any, become difficult to read.

When identifying any of the listed features or suspicion of their presence, it is better to contact the specialists.

CMOS motherboard nutrition and memory

So, the external inspection did not help determine the service fee. So, further check its nutrition system and the CMOS memory built into it.

Turn on the power supply and look at the signal LED placed on the MP. If it is burning, then the power comes to it, and there is no complaints to the power supply. Unfortunately, such a power indication is not present on all MP.

If the glow is missing, and the power supply fan is motionless, then, most likely, the reason lies in the BP itself or the PC's power button. How to check these two components of the computer for performance we were explained in.

Next, making sure that the required voltage comes from the power supply, check the backup power of the CMOS memory provided by the CR2032 or CR2025 battery. What role does this memory play and how to reset it we wrote in. Remove the battery and multimeter measuring the voltage issued by it. It should be in the region of 3 V. If it does not correspond to the norm and is strongly understated, it should be replaced, because it can also cause problems that have appeared.

Phased motherboard test for performance

If the first two steps to identify the causes of the motherboard malfunction did not give, then we will test it in stages, alternately connects all the components of the system unit and focusing on the sound signals published by the speaker.

In this case, before checking the working capacity of the motherboard, and more accurately determine the defective node connected to it, disconnect all the connectors of the internal devices of the system unit from it, leaving only the power cord. In addition, removing all the RAM MODULES, the video card and other extension cards, leaving only the central processor is intact.

After, we turn on the computer and pay attention to the fact that in the absence of memory modules, the serviceable motherboard should give one short and one long beep signaling about the malfunction of RAM. If the speaker is silent, then, most likely, MP is subject to replacement.

note: All Types and Sound Signals described in this article, signaling any malfunction, correspond to BIOS Award. Which BIOS is at your MP, you need to look in the description of its characteristics.

Further, alternately add memory modules to the corresponding slots and check the speaker's reaction. Provided that the memory modules are all necessary, it should give one long and two short beeps, talking about the possible malfunction associated with the video system. Therefore, we install the video card with the next step, connect the monitor to it and check the performance of the motherboard by the presence of one beep and the appearance on the BIOS screensaver monitor.

note: Some modern MP and most of the central processors are equipped with a built-in graphic core, which allows you to do without a discrete video card. In this situation, in the absence of a video card in a slot, a serviceable motherboard will not be given sound signals corresponding to the video system malfunctions, as it will determine the presence of a built-in graphics core.

Determine whether there is a built-in graphic core in your MP or processor, you can from their operating manual or on the manufacturer's website. In any case, if the motherboard is equipped or only supports the built-in video card in the central processor, it must have an appropriate connector for connecting the monitor.

So, in this article we gave the basic methods of how to check the motherboard for the performance itself, not attracting specialists. Therefore, if you have done the above-described actions, you never identified the reasons for the PC breakage, we advise you to seek help from any service center for help.

Hello everyone. In today's article, it will be about the full diagnosis of all devices in your computer. I will show and tell you how to independently diagnose the computer and all its components:

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

All this we will check in this article and for each of the computer devices, I will make a video in which I will clearly show how to make a diagnosis of a device.

In addition, by diagnostics, you can determine whether you have to fully change the device or you can repair it, we also analyze the main sores of the devices that can be defined without diagnostics. Well, let's start with the most important you are interested in all the issue - Diagnostics of the HDD / SSD disk.

Diagnostics of HDD and SSD disk.

Disk diagnostics make in two directions check the smart system of the hard or solid-state disk and check the disk directly on batches or slow sectors to check the SMART HDD and SSD, we will use the program. You can download it from our site in the Download section.

Well, now we turn directly in the diagnostics of the disks, after downloading the program, you start the file of the desired bitness and look at the main window if you see the blue signature icon well or in English good means with your smart disk everything is in order and further diagnostics can not be carried out.

If you will see a yellow or red icon with inscriptions carefully, bad, it means that there are any problems with your disk. You can learn about the exact problem below in the list of the main diagnostic elements SMART. Everywhere where will be yellow and red icons opposite the inscription, will say that your disk suffered in this part.

If you have already exhausted the resource of the disk, then it is not worth repairing it. If you have found several broken sectors, then there is still the possibility of repair. I will tell about the repair of broken sectors further. If there are many broken sectors on the disk, more than 10 or many very slow sectors, then it is not worth restoring such a disk. After some time, he will still fall further, it will need to constantly restore / repair.

Disk software repair.

Under repair, I mean the relaxation of broken and slow sectors on the disk. This instruction is suitable for HDD disks, that is, only hard drive. For SSD, this operation will not help anything, but will only worsen the state of the solid-state disk.

Repair will help some more extend the life of your hard disk. To restore broken sectors, we will use the HDD Regenerator program. Download and run this program, wait until the program will collect data about your drives after the data will be collected. You will see the 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. Click on the inscription you need to quickly in OS 8 and 10, so the window quickly disappears, in 7 everything is fine. Next, click NO. Then you choose your disk in the list. Press the Start Process button. A window appears in the form of a command line in which you will need to press 2, ENTER, 1, ENTER.

After the operations proceeded, the system will begin to scan the system for the presence of broken sectors and move them to non-readable disk partitions. In fact, broken 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 recovering a disc can take a long time depends on the volume of your disk. After completing the program, press the 5 and ENTER button. If you have any errors during testing and fixing broken sectors, it means that your disk cannot be restored. If you have been found more than 10 blades - broken sectors, then restores such a disk does not make sense, there will be constantly problems with it.

The main signs of failure of the disks is:

departures to blue screen.

windows interface hang.

there may be other problems, but it is not possible to tell about all.

Diagnostics of RAM

This time we will conduct diagnostics of RAM. There are several options in which you can check the RAM, this is when you have a computer still turn on and something works and when you can not turn on the computer, only the BIOS is loaded.
The main signs that the RAM does not work:

When booting resource-intensive applications, the computer freezes or reboots.
With long-term use of a computer, more than 2 hours, Windows begins to slow down, with an increase in time, the slowdown in operation increases.
When installing any programs, you cannot install them, the installation is completed with errors.
Sound and form.

The first thing we will analyze is how to check the RAM if your Windows is loaded. Everything is very simple, in any of the operating systems starting with Windows Vista you can dial the Windows Memory Checking Tool. The newly appeared label on behalf of the administrator and see a message that you can reboot and start checking right now or assign the check when you turn on the computer. Select the value you need. After your computer is rebooted, you will immediately automatically start the RAM test. It will be held in standard mode, wait for the end of the test and you will find out if everything is in order with your RAM. In addition, after Windows already downloads, in the event viewer, you can open Windows logs, select System and on the right in the list Find Memory Diagnostic Event. In this event you will see all the information about the diagnostics. Based on this information, you can find out whether RAM works.
The following variant of the RAM diagnostic in case you cannot download Windows. To do this, write to the disk or on the boot flash drive program and run it from the bios. In the window that appears, the operational memory test check (RAM) will be automatically launched. Wait for the end of the check and if with your memory there are any problems of the dough window will change with blue on red. It will talk about defects or breakdown of RAM. That's all, you found out - how to diagnose RAM.

Video about how to check RAM:

Diagnostics of the video card

Basic signs of a video card defect:

The computer knocks out the blue screen of death.
Artifacts appear on the screen - multicolored strip points or rectangles.
When loading games, the computer freezes or reboots.
With prolonged use of a computer in the game, the performance is reduced, the game begins to lag.
Showering video, refusal to play video, problems with flash player.
Lack of smoothing in the text and when rewinding documents or web pages.
Change color gamut.

All these are signs of any video card defects. Testing the video card must be divided into two stages: checking the graphics chip and checking the video card memory.

Check Graphic Card Video Carts (GPU)

To verify a graphic chip, you can use various programs that provide a load on this chip and detect failures during critical load. We will use the program, and FurMark.
Run Aida at the bottom of the clock with the right button next to the clock and select the system stability test. In the window that appears, we put a tank opposite the GPU Stress Test. The test will be launched at the bottom you will see a chart of temperature change, the speed of rotation of the fans, and the current consumed. For checking enough 20 minutes of test, if at this time the bottom field with the schedule will become red or the computer will reboot means with your video card there are problems.
Run OCCT. Go to the GPU 3D tab, do not change the settings and click the ON button. Next, a window with a shaggy bagel will appear, which is a visual test. For the test it will be necessary for 15-20 minutes. I recommend to monitor the temperature and follow the power readings, if multicolored points, strips or rectangles appear on the screen, it will say that with a video card problem. If the computer spontaneously turns off, it will also say about the video card defect.
Now we have disassembled the diagnosis of the video card processor, but sometimes there are problems with the memory of the video card.

Diagnostics of the video card memory

For this diagnostics, we will use the program. Unpack the program and run it on behalf of the administrator. In the window that appears, we put a check mark opposite the inscription signal if there are errors and press the start button. Verification of the video card RAM will be launched if any memory errors are detected, the program will have a characteristic beep, on some computers the signal will be systemic.
That's all, now you can do the diagnosis of the video card yourself. Check GPU and video card memory.

Diagnosis of motherboard

Basic signs of motherboard malfunction:

The computer knocks out the blue screen of death, restarts and turns off.
The computer freezes without rebooting.
Hences the cursor, music and video (friezes).
Connected devices are disappeared - HDD / SSD, drive, USB drives.
Ports, USB and network connectors do not work.
The computer does not turn on, does not start, not loaded.
The computer works slowly, often slows down or hangs.
The motherboard publishes various sounds.

Visual inspection of motherboard

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

Chips and cracks - in the presence of such damage, the motherboard will not turn on at all or will be included in times.
Swimmed capacitors - due to swollen capacitors, the computer can turn on with 3, 5, 10 attempts or after a certain time, can also be shine without reasons and slow down.
Oxidation - the computer can be turned on in times, slow down. May not turn on at all if the tracks oxidized completely.
The heated chips, on the microchips there will be small gary points or holes - because of this, the computer may not turn on or ports, northward cards, sound or USB will not work.
Scratches on the tracks - the same as under the chips of cracks.
Gare around chips and ports - leads to the complete inoperability of the motherboard or its individual parts.

Motherboard software diagnostics

If your computer is turned on and loaded Windows, but there are incomprehensible glitches and braking, it is worth making a programmatic diagnosis of a motherboard using the program. Download and install the program, run it downstairs in the tray near the clock at its icon, press the right button and select "SERVICE" - "System Stability Test. We put the ticks opposite the Stress CPU, Stress FPU, Stress Cache, do the remaining ticks. Press the "Start" button, the computer will move, the passage of the test will begin. During the test, monitor the temperature of the processor and motherboard as well as the power. Test take at least 20 minutes Max 45 minutes. If during the test the lower field will become red or the computer will go out, then the motherboard is faulty. Also shutdown can be due to the processor, remove a tickStress CPU and check again. If you detect overheating, then you need to check the motherboard cooling system and processor. When fluctuations in nutrition, problems are possible both with the motherboard and with BP.

If the computer starts, but Windows is not loaded, you can check the mainland through the boot test. It must be recorded on the disk or flash drive. In more detail how to use it, I will show in the video.

Diagnostics of the power supply (BP)

The main features of the power supply fault:

The computer does not turn on at all.
The computer starts for 2-3 seconds and stops work.
The computer turns on from 5-10-25 times.
When the computer is loaded, it reboots or throws the blue screen of death.
With load, the computer slows down.
The devices connected to the computer are spontaneously disconnected and connected (screws, drives, USB devices).
Sisk (whistling) when working on a computer.
Unnatal noise from the Fan BP.

Visual inspection of BP

The first thing to do with the power supply malfunction is to make a visual inspection. Disconnect the BP from the case and disassemble the BP itself. Check on:

GARS, glowing elements of BP - see that all the elements would be integer if they found in or obviously something melted, carrying PBS into repairs or change to a new one.
Swim capacitors - replace swollen capacitors to new ones. Because of them, the computer can be turned on not from the first time or shine under load.
Dust - If the dust has been scored in the fan and radiators, it must be cleaned, because of this, the power supply in the load may turn off overheating.
Burnt fuse - when the voltage drops, the fuse is often lit, it must be replaced.

Checked everything but the power supply behaves badly, look.

Software diagnostics BP

The software diagnostics of the power supply can be carried out using any test program that gives the maximum load on the BP. Before making such a check, it is necessary to determine if all the elements of your power supply power PC are enough. You can check this as follows: Run the AIDA 64 program link above and go to the Calculation site of the required power of BP. On the site to transfer data from AIDA to the right fields and press the Calculate button. So we will be sure exactly what power supply power is enough for a computer.

We proceed to the diagnosis of BP. Swing the program. Install and launch it. Go to the POWER SUPPLY tab. We put a tank to use all logical kernels (not on all computers) and press the ON button. The test lasts an hour and if the computer turns off at that time, it restarts, knocks out the blue screen, there are problems with BP (before checking the BP you need to pre-check the video card and processor, to avoid infernity of the test).

I will not show how to make diagnostics of the BP multimeter, because this information is in the shaft in the network, and it is better to make such a diagnosis of professionals. Bole in detail Testing BP I will show in the video below:
