entranceWorking with windjview 2.1. Description of the WinDjView program
From time to time it becomes necessary to find out what hardware is on the computer (video card, hard drives, processor, etc.) and brief information about the system (how much is there, how much memory it takes). For the sake of such a case, it makes no sense to open the computer case, especially if it is under warranty, since there are a bunch of all kinds of utilities, including a large number of free ones, that will tell almost everything about your computer. The main thing here is not to get confused by the abundance possible options and find a utility that suits you. If you don't need detailed information about every component of the computer and all installed programs, then you should pay attention to free program.
Immediately after starting the installation of Speccy, we are immediately offered to choose the language that the application will use by default, in a large list of several dozen options there was a place for Russian localization. Then there are more familiar questions, where to place icons to start the program and whether it is necessary to automatically check for an update. Well, in the end, as a dessert, they are trying to offer to install google browser Chrome (by the way, quite good) and do Google search engine by default, which I advise you to refuse, if necessary, you can put it by hand. Then you need to wait until required files will be unpacked and the program will be ready to work. Although I was very surprised by the inability to choose the directories where Speccy will be located.
Alternatively, Speccy can be used as a portable program that can be run with USB stick on any computer, just unzip it into a suitable folder.
Launching Speccy, we get a nondescript gray window, where a list of all found devices and hardware is displayed in the left column, where you can switch between individual items by clicking the mouse, and with right side detailed information about the selected item. The program gives out quite detailed information about the processor, random access memory, motherboard, video card, hard drives, optical discs, external peripherals and network connections. I almost forgot, you can click on the points where the temperature and frequency are indicated, after which a beautiful plate will pop up, with a graph clearly showing how the temperature has changed specific device with time.
There is no point in describing each item in particular, the name speaks for itself, and no one has yet canceled experiments on poking at all the buttons that can be pressed.
Users are offered a minimum set of settings, where the most useful items are the choice of language and in which units the temperature will be displayed.
If you need to quickly find out what hardware on your computer and basic information about the system Speccy will be an excellent choice. The program knows everything even about the newest hardware, so it will not be confused even by a very tricky computer configuration. The best part is that there is nothing superfluous. Speccy just does its job without asking unnecessary questions.
The program works great on 32 and 64 bit operating systems Oh. Interface localization is available in several dozen languages, including Russian.
Even the weakest Personal Computer is difficult digital system, often failing for a number of reasons. Like any other technique, the PC is subject to diagnostics, the main part of which is to check it special programs... Some of them are bundled with drivers for system components, but the bulk of this kind of software is unified with most device models, detects several diagnostic parameters at once and is distributed on a free or shareware basis.
Today we will tell you about 10 computer diagnostic programs that are available to every user.
The first on the review in this article, the Speccy program is the creation of the British IT-company Piriform, which created the popular utility for cleaning the computer from garbage CCleaner. Speccy will help diagnose computer hardware, displaying basic information about each installed device on board: processor, video card, motherboard, hard drive and other components. The software is distributed by the company free of charge for private use, and can be run on outdated and new operating systems. Windows systems including XP.
After installing and launching Speccy for the first time, without additional greetings, it immediately gets down to business - the analysis of the installed equipment. The main indicators are instantly displayed in the " general information". In the left tab bar, the user selects the device of interest. In addition to the hardware data included in the firmware, Speccy displays the current temperature of the device, and can warn the owner about critically high values. For the convenience of exchanging diagnostic data, the program implements the function of snapshot data in the form of an image or saving them in XML and TXT format.
Advantages:
- displays information about the type, manufacturer, batch number, year of manufacture, firmware version, etc .;
- takes readings from temperature sensors;
- displays nominal and current frequency indicators;
- saves the received information in the form of a document or image;
- has a simple no-frills interface;
- full-fledged free software in Russian.
Disadvantages:
- there are no diagnostic tools (tests) to check the stability of the system;
- displays an incomplete list of component parameters.
CPU-Z
The CPU-Z program can be safely called the world's most popular system analyzer for Windows based... It provides comprehensive information about the processor, RAM and its subsystem, and graphics adapter... CPU-Z is completely free and compatible with all existing ones today Windows versions.
CPU-Zet favorably stands out among competitors in two qualities: a great depth of computer analysis and the simplicity of the shell. With its help, you will learn about such parameters of your processor as the type and technical process of the chip, its heat dissipation, core voltage, revision and stepping, as well as the level and capacity of the cache. The same detailed report is available for RAM and chipset motherboard... This data is indispensable for both overclocker enthusiasts and ordinary users who are fond of upgrading and customizing their computer. However, information about the video system is presented here in a compressed form, and the hard drive is not affected at all.
In addition to dry textual layout, CPU-Z can carry out simple stress tests of the system to check its stability under load. Test reports and PC health reports are saved as TXT and HTML document.
Appearance the utility is extremely simple and has not changed since the beginning of its development. Moving through the points is done through the tabs in the upper panel. There is also a portable version for launching from a flash drive or other media.
Advantages:
- maximum information content about CPU, RAM and chipset;
- works on a computer with any version of Windows;

GPU-Z
A video card is practically a full-fledged "computer in a computer" with its own subsystems and operating modes. Therefore, the developers from TECHPOWERUP have developed a separate program for checking the computer's video system - GPU-Z. Its basic principles are the same as those of CPU-Z - complete information content and ease of use. It is available online for free.
GPU-Z is indispensable and necessary tool for everyone who is interested in what his computer consists of. The utility will inform you about all the parameters of the video core, video memory and power subsystem, up to the device identification code and BIOS version... In addition, the GPU-Zet scans the current readings of the temperature and frequency of the chip, the frequency of memory chips, the rotation speed of the cooling fan, the load and voltage per core, etc. All these values are fixed at the request of the owner in text file or a screenshot.
The utility has earned special recognition for its ability to identify "fake" video cards that do not meet the characteristics stated in the BIOS. You will notice the status "" next to the name of such a card, and instead of the vendor's image, you will see Exclamation point.
Advantages:
- a full report on the characteristics of the video card and its current state;
- simple interface shell;
- saving the report as a document or a screenshot;

HWMonitor
The HWMonitor program from CPUID is used for complete computer diagnostics, determining its operating parameters and operating modes. Unlike the well-known product CPU-Z from the same company, the Hardware Monitor provides a comprehensive check of the hardware status in real time, but without providing data on characteristics and firmware. The software is presented by a free and paid PRO version.
HWMonitor is a single table that displays the devices installed in the system, and indicates their voltage and operating frequency, heat pack, cooler rotation speed, temperature on the sensors and the percentage of workload (work) or occupied memory. Since the utility does not display firmware data, it is better to use it in conjunction with other products, for example, CPU-Z, for overclocking and tuning. The available readings can at any time be written by the user to the TXT notepad file.
The HWMonitor PRO version is equipped with additional functions for remotely checking the readings of computer sensors via a smartphone or another PC. It also has a collapsible temperature panel for working in the background during overclocking and heating control. electronic components.
The program interface is minimalistic, and does not have additional functions and decorations.

- there is no detailed information about the performance of the hard drive according to S.M.A.R.T .;
FurMark
FurMark has been the unspoken benchmark for testing high-performance graphics cards and embedded video systems in a computer for many years. It is a set of stress tests for testing the graphics subsystem for stability and maximum performance in 3D with OpenGL API support. FurMark receives regular updates and is distributed free of charge.
Fur Mark consists of a settings dialog box and a test window, in which a complex render of a toroidal object (or in the popular way - "hairy donut") rotates. Before starting the test, you must select the graphics level and operating mode. In addition to resolution and anti-aliasing, the user can enable full screen instead of windowed mode. An important point it is worth indicating the time of the test, since a long-term presence of the video accelerator under one hundred percent load can disable the device.
After pressing the button « GPU stress test» a rotating object appears on the screen, for which the entire resource of the video card is consumed. The upper part shows a graph of changes in the temperature of the video core. Depending on the given parameters the test stops automatically after certain time or in manual mode user.
Advantages:
- checking the video card under the maximum permissible load for stability, performance, power consumption;
- several modes of "running" the test;
- simple interface without unnecessary elements;
- includes utilities GPU-Z and GPU Shark;
- free software.
Disadvantages:
- FurMark puts extreme stress on the video adapter, which can lead to dumping of the graphics chip, memory chips and other "unpleasant" consequences;
- the interface is not Russified in the official version.
A warning! We do not recommend downloading this program to those who have just started to get acquainted with the computer device. FurMark has caused many computer breakdowns due to improper testing and overheating of radio components. Before starting Fur Mark, make sure that your video card has a powerful cooling system. We do not recommend running the test for more than 5 minutes.
SpeedFan
A simple and undemanding utility SpeedFan will help you monitor the main indicators of computer devices, such as fan speed, voltage, CPU core frequency, component temperature, etc. For almost 20 years, this software has been the favorite tool of many overclocking enthusiasts and ordinary users. SpeedFan can be downloaded for free on the developer's website.
Speed Fan is a universal tool for real-time computer monitoring. With its help, you can change the speed of the fan impeller, control the processor frequency, monitor the readings of temperature sensors and check the voltage at the terminals of the power supply along the 3.3V, 5V and 12V lines. In addition, it displays the S.M.A.R.T. report. the status of the hard disk. Knowing these indicators, the user can increase the heat dissipation or vice versa, reduce the noise. system unit.
The program interface, in addition to the standard Windows shell, includes many graphs for a visual representation of changes in indicators. There is also a warning function when the set temperature thresholds are exceeded, and the "CPU Usage" scale will tell you about the load of each CPU core.
Advantages:

3DMark
On this moment it's hard to find a better quality and better looking tester than 3DMark from Futuremark (now UL Benchmark). Its tasks include checking the performance of the bundle CPU+ video card. The developer offers several versions of the benchmark: free Basic Edition with reduced features, Advanced Edition with a large number tests and settings, and Professional Edition (available for commercial use).
The main feature of this tester is the increased requirements for the computer hardware, therefore, even on mid-level systems, the user may be surprised at the low number of points received. Second " business card»3DMark can be noted for colorful, well-developed three-dimensional scenes that simulate games during the test. The tests are carried out not only with qualitative, but also with quantitative scenes, which load the CPU more. 3DMark supports all modern technologies graphics processing including DirectX 12 and NVIDIA RTX and DLSS.
At the end of the test, you will see the result obtained in the form of points scored for the system as a whole and for each device separately. Your result can be published and compared with others in the rating created by other users.
Advantages:
- the benchmark loads the system by 100% without leading to breakdowns;
- reference tester for high performance systems;
- beautiful 3D models and scenes;
- there is free version 3DMark Basic Edition;

PCMark
Another product from the Finnish company Futuremark, focused on testing the performance of the system as a whole. It differs from 3DMark in a wider coverage of subsystems to be checked. With its help, the user will determine the capabilities of his PC in rendering and editing video, complex calculations, storing and transferring data from ROM and other tasks. Free Basic and paid Advanced Editions are available for download.
Computer performance analysis follows the same principle as in 3DMark, but now taking into account all major components. For example, PCMark checks the read and write speed of RAM and permanent memory (hard HDD or solid state SSD disk), the performance of each processor core, the speed at which objects are drawn on the screen by a video card. He also conducts performance tests when working in the browser, watching videos and while talking through voice VoIP clients, as well as for a while. Windows startup... To determine the suitability of the PC for games, the developers implemented some tests from 3DMark here.
At the end of the test run, the user will see the result on the screen in points, which can be used to judge the performance of the PC, based on the rating. If it identifies problematic slow devices, the tester will inform you about the need to upgrade them.
Advantages:
- general performance test of the entire computer with explanations of the problems;
- analysis of the state of the operating system;
- reconciliation of the result with the "live" rating of other users;
- very user-friendly and beautiful interface;

Advantages:
- simplicity and detail of the report;
- convenient control and configuration;
- high measurement accuracy of sensor readings;
- BIOS and driver update;
- completely free software.
Disadvantages:
- there are no tests to check the stability and performance of the system.
Conclusion
Among the ten programs we have considered for diagnosing a computer, there is no ideal option - each has a set of its pros and cons. However, we can advise you to make a choice in a particular situation for specific tasks supplied by the user.
For a standard and comprehensive computer scan, we would choose Speccy, HWMonitor, HWiNFO, and PCMark. They provide detailed data on the characteristics and the current state of the hardware and operating system, and PCMark will help you load and test your PC for performance without risk.
For more demanding users, overclockers and gamers, AIDA64 Extreme, 3DMark and FurMark are the best options. The first program displays data about the PC at the highest possible level, and the other two are perfect for testing video adapters.
CPU-Z, GPU-Z, and SpeedFan will work with any of the groups, but they are more likely to have similar capabilities to the above options.
Hello everyone. In today's article, we will focus on a complete diagnosis of all devices in your computer. I will show and tell you how to independently diagnose a computer and all its constituent 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 can 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 that interests everyone - diagnostics HDD disk/ SSD.
HDD and SSD disk diagnostics.
Diagnosis of the disk is done in two directions check Smart systems of hard or solid state drive and check directly the disk for bad or slow sectors in order to check 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 bit rate 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 you can skip further diagnostics.
If you see a yellow or red icon with the words cautiously, badly, then there are some problems with your disk. You can find out about the exact problem below in the list of SMART Essential Diagnostic Items. Wherever there are yellow and red icons opposite the inscription, it will indicate that it was in this part that your disk suffered.
If you have already exhausted the disk resource, then it is no longer worth repairing it. If you have found several broken sectors, then the possibility of repair is still there. I will tell you about the repair of broken sectors further. If there are a lot of bad sectors on the disk, more than 10 or a lot of very slow sectors, then it is not worth rebuilding such a disk. After a while, it will still crumble further, it will need to be constantly restored / repaired.
Disk repair software.
By repair, I mean relocation of bad and slow sectors on the disk. This instruction suitable only for HDD drives, that is, only hard drives. For SSD this operation will not help, but will only worsen the condition of the solid state drive.
The repair will help extend the life of your hard drive a little more. To recover bad sectors, we will use the HDD regenerator program. Download and run this program, wait while the program collects data about your disks 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. Click on the inscription you need to quickly in OS 8 and 10, so the window will quickly disappear, at 7 everything is fine. Then press NO. Then select your disk from the list. Click the start process button. A window will appear in the form command line in which you will need to press 2, Enter, 1, Enter.
After the operations done, the system will start scanning for bad sectors and moving them to unreadable disk partitions. In fact, the 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 disk verification and repair process can take a long time, depending on the size of your disk. At the end of the program, press button 5 and Enter. If you have any errors while testing and fixing bad sectors, it means that your disk cannot be recovered. If you have found more than 10 bad - 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:
Video on how to diagnose HDD / SSD:
RAM diagnostics
This time we will carry out diagnostics of RAM. There are several options in which you can check the RAM, this is when your computer is still turned on and is working somehow, and when you cannot turn on the computer, only BIOS is loaded.
The main signs that the RAM is not working:
- When loading resource-intensive applications, the computer freezes or restarts.
- With a long-term use of the computer, more than 2 hours, Windows starts to slow down, as the time increases, the slowdown increases.
- When installing any programs, you cannot install them, the installation fails.
- Sound and video jamming.
The first thing we'll look at is how to check your RAM if your Windows boots. Everything is very simple, in any of the operating systems starting with Windows Vista You can search for a validator Windows memory... Launch the appeared shortcut as administrator and see a message stating that you can restart and start the scan right now, or schedule a scan the next time you turn on the computer. Choose the value you need. After the computer restarts, the RAM test will automatically start for you. 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 Windows logs, select the System item and find the memory diagnostic event on the right in the list. 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 in case you cannot boot Windows. To do this, you need to write to disk or bootable USB drive program and run it from BIOS. In the window that appears, a test to check the random access memory (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 talk about defects or damage to the RAM. That's all, you have learned how to diagnose RAM.
Video on how to check the RAM:
Diagnostics of the video card
The main signs of a video card defect:
- The computer knocks out the blue screen of death.
- Artifacts appear on the screen - multi-colored points of a strip or rectangles.
- When loading games, the computer freezes or restarts.
- With prolonged use of the computer in the game, performance decreases, the game starts to lag.
- Video jam, video playback failure, flash player problems.
- Lack of smoothing in the text and when rewinding documents or web pages.
- Change the color scheme.
All these are signs of any defects in the video card. 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 load this chip and detect failures under critical load. We will be using the program, and FurMark.
Launch Aida at the bottom of 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 start at the bottom and 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 lower field with the graph turns red or the computer restarts, then there are problems with your video card.
Launch OCCT. Go to the GPU 3D tab, don't change the settings, and press the ON button. Next, a window with a furry donut will appear, 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 shuts down spontaneously, this will also indicate a defect in the video card.
Now we have analyzed the diagnostics of the video card processor, but sometimes there are also problems with the video card memory.
Diagnostics of the video card memory
For this diagnosis, we will use the program. Unpack the program and run it as administrator. In the window that appears, put a tick in front of 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 issue a characteristic sound signal, on some computers the signal will be the system signal.
That's all, now you can diagnose the video card yourself. Check GPU and video card memory.
Video for checking the video card:
Diagnostics of the motherboard
The main signs of a motherboard malfunction:
- The computer knocks out the blue screen of death, restarts and shuts down.
- The computer freezes without rebooting.
- Jams cursor, music and video (friezes).
- Connected devices disappear - HDD / SSD, drive, USB drives.
- Ports, USB and network connectors are not working.
- The computer does not turn on, does not start, does not boot.
- The computer is slow, slows down or freezes frequently.
- The motherboard makes various sounds.
Visual inspection of the motherboard
The first thing to do to diagnose the motherboard is to visually inspect 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 one time later.
- Swollen capacitors - due to swollen capacitors, the computer can turn on after 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 once, slow down. It may not turn on at all if the tracks are completely oxidized.
- Warmed up chips, there will be small burning spots or holes on the microchips - because of this, the computer may not turn on or the ports, network cards, sound or USB will not work.
- Scratches on the paths are the same as for chipped cracks.
- Burning around chips and ports - leads to the complete inoperability of the motherboard or its individual parts.
Motherboard software diagnostics
If your computer turns on and boots up Windows, but there are incomprehensible glitches and brakes, it is worth making a software diagnostics of the motherboard using the program. Download and install the program, run it, right-click on its icon in the tray near the clock on its icon and select "service" - "system stability test". Check the boxes in front of Stress CPU, Stress FPU, Stress cache, remove the rest of the boxes. 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 the power. The test is carried out for at least 20 minutes, max 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, uncheck the boxStress CPU and check again. If you find overheating, then you need to check the cooling system of the motherboard and processor. with fluctuations in power, there may be problems with both motherboard so with the PSU.
If the computer starts but Windows does not boot, you can check the mainland through the boot test... It needs to be written to a disk or USB flash drive. I will 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 malfunction:
- The computer does not turn on at all.
- The computer starts up for 2-3 seconds and stops working.
- The computer turns on from 5-10-25 times.
- Under load, the computer goes out, reboots or throws out the blue screen of death.
- The computer slows down a lot under load.
- Devices connected to the computer spontaneously disconnect and reconnect (screws, drives, USB devices).
- Squeak (whistle) when the computer is running.
- Unnatural noise from PSU fan.
Visual inspection of the power supply unit
The first thing to do if the power supply fails is to do a visual inspection. We disconnect the power supply unit from the case and disassemble the power supply unit itself. We check for:
- Burn, flooded elements of the power supply unit - we look to ensure that all the elements are intact, if we find a burnout or obviously something melted, we carry the power supply unit 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 power supply unit in the load may turn off due to overheating.
- Blown fuse - when the voltage drops, the fuse often burns, it must be replaced.
We checked everything, but the power supply is behaving badly, we are looking.
Power supply software diagnostics
Software diagnostics of the power supply can be carried out using any test program that gives the maximum load on the power supply. Before doing such a check, it is necessary to determine whether the power supply of the power supply is sufficient for all the elements of your PC. You can check it like this: run the AIDA 64 program link above and go to the site for calculating the required power supply. On the site, transfer the data from Aida to the appropriate fields and click the Calculate button. So we will be sure exactly how much power the power supply is enough for the computer.
We proceed to the very diagnosis of BP. Downloading the program. Install and run it. Go to the Power Supply tab. put the checkbox to use all logical cores (it 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, reboots, 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 to avoid incorrect test).
I will not show how to diagnose a power supply unit with a multimeter, because there is a lot of this information on the network, and it is better for professionals to do such diagnostics. I will show you the PSU testing in more detail in the video below:
