The main task that the program performs for diagnosing a computer is to obtain as much information as possible about the software and hardware of the device.
It determines whether there are enough resources to run a particular application, check the characteristics of the system, components, and their state.
Especially important are such programs for a person who for some reason needs to know the parameters of someone else's computer and to correct errors. Determine how much memory is installed on your computer, its type and number of slots. After that it will be much easier to choose a new suitable RAM or draw conclusions that it is worth replacing the entire motherboard or computer (laptop);
CPU-Z
Distributed free of charge program CPU-Z has unpretentious interface and allows you to receive technical information about almost all elements of the computer:
- Processor (including its model, architecture, socket, voltage, frequency, multiplier, cache sizes and number of cores);
- Motherboard (brand, model, BIOS version, supported memory types);
- RAM (volume, type and frequency);
- Video card (name, volume, volume, type and frequency).
The main advantages of the application is the ability to get detailed and accurate information in Russian about all the components of the system, which can be useful for professional users and amateurs.
Among the minuses is the inability to determine the temperature of the processors.
Speccy
Another one free program gives the possibility of obtaining detailed information about all the main components and software, starting from the processor and the board, ending with RAM and optical disks.
In addition, with the help of Speccy, you can obtain data from temperature sensors, by finding ways to correct connection errors or install ventilation systems.
Naturally, the application determines the number of RAM slots, which can be an important factor in determining the need and possibilities for upgrading the computer.
And when preparing the device for sale Speccy can be used to quickly compile a list of components - in fact, although almost the same allow you to make built-in utilities, you will need more time to do this, and some data will not be recognized.
It should be noted that the developers of the program are the authors of such useful software as CCleaner and Defraggler.
And among its advantages are noted:
- Clear and practical interface;
- Quick access to important information;
- No need to install the application, which may be needed, for example, if you do not have access to account administrator;
- Ability to monitor the selected parameter in real time by setting it as an icon in the tray;
- Running simultaneously with the system;
- Free access
HWiNFO
Thanks system application HWiNFO, you can get maximum useful information about the system, compare the performance of individual hardware components with the template parameters and the performance of popular analogs.
In addition, the program allows you to create reports that you can use to compare the performance of individual elements of the PC.
All the information is quite detailed, but it concerns only the equipment - it will not be possible to learn about it with its help.
However, this drawback is almost the only one, since the application is able to collect data on any devices, including even outdated equipment (for example, IDE and modems for dial-up access), old BIOS and video cards of any type.
In addition, the application can also test the processors, memory and disks. Data obtained as a result of the test can be stored in the logs. And you can control individual parameters with the help of icons in the tray, which periodically change.
AIDA64 Extreme
Using the application AIDA64 Extreme gives the user the opportunity:
- Obtain information about hardware components;
- Determine which drivers are installed on the computer, and, if necessary, search for their latest versions;
- Monitor the temperature of the processor, responding to faults and correcting them;
- Test 64-bit operating systems (for the 32-bit version there is a special version - AIDA32) and the equipment with the help of unique utilities;
- Diagnose and control the speed of rotation of the fan blades and voltage;
- Save the received data as a document of any format.
Advantages of the program - obtaining almost all useful information about the system and the computer.
Among the shortcomings is the limitations of the free demo version and the high cost of the application, especially for the domestic user.
PassMark Performance Test
The PerformanceTest application is a set of tests that you can use to evaluate the performance of your computer by comparing it with the performance of other devices.
The latest version of the utility has 27 programs built in, each of which is responsible for defining its data category.
Among them are tests for:
- Processor (for encryption, data compression and computation speed);
- Video cards (for the possibility of bit-mapped display of 2D and 3D graphics, animation, compatibility with graphics packages such as DirectX);
- Hard disk (for writing, reading and data retrieval speed);
- Optical drives (speed of reading, saving data;
- RAM (access to data, speed).
Results are saved in most popular formats - from HTML to Word, after which they can be sent to e-mail, paste into the website code, edit in a text editor or print.
And the tests themselves can be imported into the application, adding new features.
The main tasks of PerformanceTest are:
- Determine the capabilities of the PC for comparison with minimum or optimal game requirements;
- Checking the components to fix the iron malfunction;
- Help in making decisions when updating a computer's configuration or purchasing a new one;
- Creating your own tests.
Meanwhile, the program is not distributed free of charge. Part of its features, including the improvement of graphic tests, is available only for the version that you will have to buy.
Although an application that is freely available is functional enough and allows you to use a variety of settings. Turn to the menu
CrystalDiskMark
Small in size and therefore quickly downloaded from the network program was created in order to conduct tests with hard disks of any type (HDD or SSD) and with all kinds of interface.
The main parameters that are determined by the utility are the write and read speed.
As a result, you get an extended count, which is unlikely to be useful to a layman, but for an experienced user and a person who determines what problem exists with your drive, it is almost ideal.
In this test can be conducted several times in a row, automatically averaging the results.
SpeedFan
An application suitable for searching for problems with the computer - malfunctions of motherboards and graphics cards, disks, processors and coolers with interfaces of different types.
A small drawback is the difficulty of reading data from some hard disks, connected with the IDE connector.
However, the functionality of this software is sufficient for:
- Fan speed and voltage settings;
- Setting the temperature limits for processors, the excess of which the application reports to the user;
- Memory Decode different types (from SDRAM to DDR4).
AT recent versions The utility has support for Windows 10. The application is multilingual, including works in Russian.
And its main advantages include not only a warning for the user to respond to the malfunctions (which can not be done by every similar program), but also displaying the controlled temperature in the tray.
At the same time SpeedFan is distributed free of charge.
SIW
PC users who wish to determine the system and component settings can also use an application such as SIW, whose name can be decrypted as System Info for Windows.
It has a small size and a simplified interface, reminiscent of the standard Windows utilities and is capable of issuing all the most necessary information for the user.
For example, using SIW you can learn about latest updates systems, get information about system files or folders, as well as about drivers, running processes and services - and, in more detail, than the "Task Manager" does.
For commercial or corporate use, you must purchase a license.
conclusions
Number of programs for testing equipment and operating system sufficiently large.
Almost all the time, new applications are being created to help monitor the computer's parameters and iron malfunction.
But the programs presented in the list allow you to do this as efficiently as possible by installing only 2-3 applications, not a dozen applications - saving time and not downloading extra files from the network, at the risk of accidentally putting a virus on the computer.
In addition, if there is no network access, there are a number of utilities in Windows that also allow you to learn some parameters.

Hello, dear readers! Many PC users do not even think that at one point the computer can shut down forever. Yes, yes, that's how it can happen absolutely with any computer. And often there is a problem that new computer refuses to work.
But worst of all, if the PC malfunction arose suddenly. In this case, you need to properly identify the problem, because sometimes repair is not needed. In such cases, an excellent assistant for you will serve . And there may be several programs, it all depends on what you specifically diagnose.
So, in today's article, we'll look at programs for diagnosing your computer. Imagine a situation where the computer does not leave much to be desired and frequent causes are a constant spontaneous shutdown of the computer and, of course, its freezing. The question arises: What is the problem and, most importantly, what are the reasons?
First of all, you need to identify the causes of malfunctions. As you know, the unfavorable climate and dust significantly worsen the condition of computer components. The main causes of failure of iron:
- oxidation of contacts;
- getting dust on the connectors and chips and their overheating;
- overheating due to poor cooling;
- voltage jump;
- instability of the power supply unit;
- improper grounding.
In one of the previous articles, I considered in detail the above-listed faults, how to fix them, what to do, etc. Be sure to read the following articles:
Program for computer diagnostics
The first way diagnosis is very trite, but effective. You can test the operation of individual units by touching them with your hand to check their heating. After turning on the PC for 60 seconds, the processor, chipset, video card units and memory chips should be warmed. If they are warm, then this indicator is enough to conclude that the food for these elements is fed. It is very likely that they must be workers.
If you have no idea what is inside at all the system unit, then in this case I strongly do not recommend you to perform a check in the above way. And I can recommend reading the article for an overview of the components of the PC.
The second way hardware diagnostics is more scientific and will require some engineering skills. It consists in measuring potentials on various elements. This requires an oscilloscope and a tester. It is best to have a wiring diagram at hand motherboard PC, because it has many layers and some signals are not so obvious.
The measurements begin with the power elements of the input circuits, as well as shunt and stabilizing capacitors, the presence of +5 and +3.3 V, the operation of the clock generators are checked. After that you need to check the presence of standard signals on the socket of the processor. Then check the signals on the ports and slots. Logical elements are best dealt with in the last place, since often their repair is unreasonable. In general, knowledge in this area to you certainly will not be superfluous.
The last method hardware diagnostics are professional tools. These include DP-1 diagnostic cards and PC-3000 complex, which was created by ROSC. A special diagnostic fee is installed on the free "mother" slot. After turning on the computer, the indicator shows the fault code in hexadecimal. Using the board significantly increases the chances of localizing the problem. The use of DP-1 is designed for normal operation of the CPU CPU, which rarely fails.
Software diagnostic methods
And now let's talk about whether there is any computer diagnostic program, the results of which helped to identify the faulty node or at least would characterize the change of a specific parameter.
If your PC turns on, but there is instability, a hang on boot, the appearance of BSOD ( blue screen death), this is often a consequence of local overheating, overclocking, or "glitches" of memory, as well as "hard" errors.
Their work can be checked under DOS if you boot from the system disk. For this, it is best to use such utilities as:
- AnVir Task Manager - a utility for diagnosing and maintaining the OS;
- Victoria - utility for testing hard drive;
- SpeedFan - a program that allows you to measure the speed of the fan speed, as well as the temperature in the PC.
- Memtest 86 - the program for checking random access memory for errors;
- AIDA 64 - utility that provides information about the PC. Below is an overview of this program.
To describe each program, I think, it makes no sense, I just repeat that there are such programs, it remains only to use the search engines and download them.
For professional recovery and "hard" test it is better to use MHDD or HDDUtility, which correctly work only under MS-DOS 6.22. And to check and diagnose bad, it's best to use Norton Disk Director.
And, of course, do not be lazy, from time to time perform at least a simple cleaning your computer from the accumulated system files, for example I can advise you the CCleaner program. How to use this program read below.
It is also worth remembering that a full-fledged PC hardware test can be done only under Windows, by carrying out a stability test in burn-in tests throughout the day. Such tests include:
- CPU Stability Test;
- CPU Hi-t Professional Edition;
- Bionic CPU Keeper;
- Hot CPU Tester;
- DiskSpeed 32;
Completing today's article - "Program for diagnosing a computer" I would like to note that any problem and malfunction can be prevented in advance, and it is much easier than then to eliminate it. For this reason, it is necessary to regularly (once every couple of weeks) monitor the power supply parameters, view the SMART parameters of the hard disk, monitor the CPU temperature, and monitor the absence of extraneous sounds. In the next issue we will know =\u003e
And what programs for diagnostics you had to use, dear readers. I would be glad if you add your wishes in the comments. Well, for today it's all for everyone yet!
Dear users, if you have any questions after reading this article, or if you want to add something about the subject matter of this article or the whole online resource as a whole, then you can use the comment form. Also ask your questions, suggestions, wishes ..
So, for today it's actually all that I wanted to tell you in today's issue. I can only hope that you found interesting and useful information in this article. Well, I, in turn, wait for your questions, wishes or suggestions regarding this article or the whole site as a whole
Many modern users do not know that at one point absolutely suddenly for them the computer can be disconnected forever, and this can happen with absolutely any PC. It is worth noting the fact that quite often there are various problems associated with the fact that even a completely new computer stops functioning normally.
This is worst of all, when such problems occur absolutely unexpectedly for the user. In such situations, it is important first of all to correctly identify the problem, because often enough you can solve everything yourself, without the need for physical repairs. It is in this case that it is extremely important that the user knows how to do the computer diagnostics. For an ordinary person this problem is solved with the help of specialized utilities, which are selected depending on the type of diagnostics you need.
In this article, we will try to consider several utilities so that the user can determine on his own what the program for diagnosing the computer for a malfunction is suitable for. Thus it is necessary to tell at once that if necessary you can choose several programs.
Why do I need diagnostics?
Nowadays, not all users correctly understand that in fact, not in any case it is necessary to apply to qualified specialists who will perform physical repair of the drive. In most situations, problems can really be solved independently using programs that are freely available. However, unauthorized actions in some cases can only do harm, and therefore, in order to understand whether it is possible to proceed to "treatment" of the computer yourself, the computer must initially be diagnosed with a malfunction.
As is known, if a computer is operated in unfavorable conditions or in a dusty room, then over time it starts to work more slowly and slowly, as the state of certain elements in its construction deteriorates. Thus, among the most common causes of malfunction modern computers should highlight the following:
- Dusting of all kinds of connectors or chips and, as a result, their overheating.
- Excessive oxidation of contacts.
- Overheating of components due to strong cooling.
- Burnout of contacts or components due to too strong a voltage jump.
- Unstable operation of the installed power supply.
- Incorrect grounding.
Why do we need programs and what do they do?
A very useful thing is a program for diagnosing a computer, obtaining complete information about its status and the characteristics of all installed equipment. Carrying out PC diagnostics and identifying faults is an extremely important element of the operation of any PC, because it depends on how effective and timely the user can react to various problems that arise during the operation of his hardware.
Consider situations where a program for diagnosing a computer may be useful.
Update / sale
If you need to upgrade your personal computer in the near future, do it overhaul, update certain components or, conversely, sell the device, you will need to know everything about your computer and make sure that it does not contain any malfunctions.
Functional Testing
Diagnosis of the computer allows you to identify all kinds of problems, malfunctions in the system, and even more importantly - the cause of the problem. Definition of all possible causes The malfunction in most cases is quite complex, the only way out in such a situation can be the use of diagnostic utilities.
If you initially make sure that the program for diagnosing your computer has been separately written to a special disk, even if you roll back your operating system, you will be able to determine for yourself which faults of which particular component caused such malfunctions.
It is worth noting that often enough the program, which will be used to diagnose a computer, will not only be able to inform the user about which components are used in his PC and in what state they are, but also to check individual elements for the presence in them of possible causes of future malfunctions. In addition, some utilities not only diagnose the computer, but also give some tips on working with it.
In this regard, in order not to suffer from the fact that the "iron friend" suddenly began to work too slowly, suddenly turn off, unstable to function or show any other whims, timely computer diagnostics and repair must be carried out.
Comparison
In certain utilities, the characteristics of the reference systems were originally laid, so the user can, if necessary, compare whether the results of testing his performance personal computer with ideal results. After the diagnostics of the on-board computer or the PC is carried out, the user already independently decides whether to upgrade certain components in the future, buy any new equipment, update the software or perform other actions.
Helpful information
Many people who do not know how to diagnose a computer, skip a large amount of useful and useful information useful for its effective work. In particular, often enough diagnostic utilities notify the PC owner that, for example, certain drivers installed on his computer are obsolete, since the developer has released a more modern version.
In this regard, it is best to carefully study the functionality of the programs you download, since the utility you choose will directly depend on how effective and useful it is to diagnose the computer for a malfunction.
Diagnostic programs
Below we will list the necessary utilities, each of which has its own functionality and purpose:
What to use?
As mentioned above, if necessary, you can use far more than one program. Diagnosing a computer for a malfunction is an extensive procedure, it is not enough to conduct only a certain action, because the computer consists of a number of components.
As you can see, different programs have completely different, not similar functionality. In this case, it should be said that in most cases it is better to install several utilities that specialize in monitoring the operation of a certain element of your computer than simply install some kind of universal software that will simultaneously monitor everything. It depends not only on the reliability and effectiveness of the diagnosis, but also on your awareness.
It is for this reason that in the majority of cases, qualified specialists use several programs at the same time, one of which monitors the video card, the second - behind the processor, etc. Particular attention should be paid to choosing a program that will monitor the activity of your hard drive.
Why the hard drive?
Few people know that the hard drive is the most complex and fragile component of a personal computer. Despite the fact that different components like a processor or a video card look like an ordinary thin card, and hDD outwardly represented as a large and protected from the outside block, in fact it is a fragile element, inside of which are miniature magnetic heads. In this case, the drive is subject to both software and physical malfunctions. And even if the computer vibrates during operation, the hard disk can be completely broken.
Testing the computer is necessary to quickly identify any problems in the operation of the system, both at the software and at the hardware level.
If the test program shows a result that is different from normal, this indicates that one or more devices are not working properly.
To get a more accurate diagnosis result, you should check your computer with several different programs.
Diagnostics with the Aida64 utility
This program is able to provide a report on the results of the work of all components of the system (hardware and software). Utility is the most popular program for testing personal computers and laptops.
The application interface is very simple, so each user can conduct tests of the required component or the entire system as a whole.
The application interface is presented in Russian.
We will perform a general scan of the computer for performance and possible problems with this application.
To start the testing process, follow the instructions:
- Open the program and click on the "Test" tab, which is in the lower left corner of the program, as shown in the figure;
- The testing tab shows all possible options Scan components such as memory. You can also diagnose the process of writing to memory and memory latency.
To test one of the elements, select it on it, and then click on the "Start" button at the top of the toolbar;
- Next, the program will show the power of the processor in comparison with other popular models and the main characteristics of the system, as well as possible problems;
Follow the steps below to get a detailed system report:
- Go to the main program window and click on the "Report" button, which is located on the main toolbar;
- The Report Wizard opens. Click the Next button to configure the outbound report in more detail;
- Select the direction of the report. It can be compiled on the basis of software or hardware components. In this case, the hardware report will consist of diagnostic results of the hardware partitions;
- Then select the report format that is convenient for you and wait until the final document is completed;
- Example text format The initial report on the hardware sections is shown in the figure below.
Testing the processor. CPU Tester Program
Testing the processor is able to show its detailed parameters. Also, using this test, you can determine the existing problems of the CPU, which slow down the computer.
Advice! If you recently purchased a computer, it is advisable to test the processor and other hardware components to ensure that all the hardware characteristics provided by the manufacturer are correct.
You can test the processor using the CPU Tester program.
This utility has a powerful functionality for testing the processor of the device and determining its main parameters. Also the program is able to identify problems and malfunctions and indicate their nature. The utility is also available online.
During the testing it is necessary to close all running programs and games, because they will additionally load the processor and the final result of testing will not correspond to reality.
After closing all running programs, click the "Run Test" button to start the process of generating and testing the CPU.
After the testing process is over, the program will open a new user window, which will show all the diagnostic results and processor parameters, as shown in the figure below. If desired, the report can be printed.
In this test case, it is shown that the processor is stable, without any malfunction.
Power Supply Testing
If your personal computer heats up too quickly, while all fans are cleaned and work stably, you need to check the power supply unit for service. It is necessary to check the supply voltage to the power supply.
- Open the computer cover and unplug the power supply from the chassis;
Computer power supply
Advice! To fix the power supply to its original position, you can take a picture of its original position.
- Plug the power supply into your network and test the switch.
To check the operation of the power supply at the software level, you can use the program speedfan, which is able to regulate the operation of the unit and control the operating modes of the computer fans.
Testing the RAM. The Memtest program
To test RAM, it is best to use the utility Memtest, which is designed to regulate the operation and detect faults in the computer's memory.
Testing is carried out as follows:
- Download and install software for testing on the developer's site www.memtest.org;
- Then you need to create boot disk or flash drive. Testing the disk will be performed in RAM, so you can determine its performance;
- You must boot the computer from the newly created disk. You can configure the boot order of devices in the BIOS of the computer.
If the testing process lasts a very long time and does not stop, this indicates that the system is functioning normally and the computer's RAM is free of malfunctions.
If any problems are found, the testing process will be stopped and the user will be notified of the errors found. Then start the process of starting the operating system of your personal computer or laptop.
Testing the monitor. IsMyLcdOK program
Monitor tests are conducted to find non-working or as they are also called "broken" pixels. Such pixels are unable to transmit color or information, so on screens with a small resolution they will be visible.
A large number of such pixels indicate that the monitor is defective or defective.
The Best Utility to check the monitor image is IsMyLcdOK. This application allows the user to quickly determine the number of broken pixels of the display.
The testing process is as follows: the screen is completely painted in a certain color, the user needs to click on any place for the tap to turn into a new color.
This change in colors helps the naked eye determine non-working pixels.
