Why is it necessary to monitor your PC system?

Any computer and laptop is a complex machine that performs many processes every second from displaying a picture on the screen to writing a letter pressed on the keyboard. That is why it is important to constantly monitor the status of your device, noticing problems that arise in time, because one incorrectly working element can break the operation of the entire machine.

Programs that conduct a complete diagnosis of the entire PC help track incorrect operation.. As an example, they can determine how much memory is installed on your laptop, as well as the type of memory and the number of slots. Why do you need this information?

The computer wizard will say that this will help find a new, more suitable RAM. With the new data, you will be able to understand whether you need to change the motherboard, whether to add memory, whether to install a more powerful processor, whether to buy an additional hard drive. Some utilities will monitor processor temperatures to tell you if thermal paste needs replacing to prevent overheating. In general, all diagnostic type applications will help you find out why your PC or any particular installed program is not working. To understand which utility to install for you, it remains to learn more about each of our ratings.

Diagnostic Highlights

Inexperienced PC users are sure that they cannot cope with the problems that have arisen, and immediately run to computer wizards and service centers without trying to figure it out on their own. However, it is enough to find out what problems may occur with your computer in order to find out what the problem is and solve it on your own.

The following can interfere with the operation of a computer or laptop:

• Overheating of microcircuits and connectors due to their dusting
• Strong oxidation of contacts
• Incorrect grounding
• Unstable power supply
• Overheating of PC components due to excessive cooling
• Burnout of components due to overvoltage or power surge

The reports that any utility will issue will tell you exactly where non-standard parameters are observed. Also, if the situation is clearly beyond your power, you can take the diagnostic result to the master or send it by e-mail.

If you have observed incorrect operation of only one element, then it is worth downloading a utility whose work is aimed at analyzing its performance. For example, for video cards, it is important that the benchmark still evaluates the performance of the PC. And to analyze the operation of hard drives, you will have to compare the results with the characteristics of drives on other devices.

Description of programs for diagnostics: top 12 leaders

We have selected all the necessary tools presented on the Internet. Programs have different purposes and diverse functionality, you just have to find the best option for you. Remember that sometimes you need to install several programs at once in order to conduct not only a general scan of the computer, but testing and comparison with analogues.

AIDA64

Tariff plans utility

AIDA64

It often stands on the devices of specialists and computer masters, because it provides comprehensive and reliable information about components, OS, other installed programs, network and external devices. This program conducts both a complete computer diagnostics, collecting the necessary system data, but tests individual elements, including RAM, helping to configure the settings for optimal operation.

This utility will be very convenient for those who are not too versed in hardware: all the information provided is located on the right side of a separate panel, besides, it is intuitively structured according to the main parameters.

This utility is good because it performs the functions of a benchmark – that is, it determines the power of the processor and video card and gives a comparison with the data of other models. She also knows how to determine the installed drivers and even look for their latest versions, if necessary.

AIDA64 gives you the ability to monitor the system in real time to monitor the load on the key nodes of the system. Review reports are issued as a document that can be saved in any format. The reports themselves, as well as the program interface, are translated into Russian, which will allow even an amateur to work with the program. By the way, you can install AIDA64 not only on any version of Windows, but also on mobile gadgets on Android, iOS and Windows Phone platforms. Unfortunately, the utility is not free, but it has a demo version, albeit a rather limited one.

It is free and supported on all Windows models from XP to 10. This utility allows you to find out the necessary data about the processor, memory, video card, hard drive and the installed operating system, and it provides information complete and in an extremely convenient form, so that even a beginner will figure it out. For example, you can use it to see the number of RAM slots and decide if you need to upgrade your PC.

Importantly, Speccy not only helps to obtain information from temperature sensors, but also suggests ways to correct connection errors or simply install a ventilation system.

The program works in such a way that when it starts, it scans the entire computer. It weighs very little, so we recommend downloading it, even if you don’t need it right now: it will allow you to control PC heating, quickly make a list of components, and even monitor the list of drivers you need to install.

The data, by the way, is saved in TXT and XML formats, so in case of a breakdown, you can show the report to the master. Do not forget that the Speccy developers are the creators of CCleaner and Defraggler, which in itself is a guarantee of quality and stable operation.

CPU-Z

This is a simple free program., which allows you to quickly obtain important technical information about the main elements of your computer. The utility is distributed in two versions, which differ in the need for installation, but in terms of performance, they are approximately the same.

CPU-Z can determine:

• Model, number of cores, architecture and processor socket
• CPU voltage, frequency, cache and multiplier
• Make and model of the motherboard
• BIOS version and memory type
• Volume, type and frequency of RAM
• Name, type and volume of video card

The main plus for Russian speakers is the ability to obtain accurate characteristics in Russian. Of course, the design of CPU-Z is quite poor, but for applications of this type it is not important, and minimalism does not complicate the perception of information.

The only real disadvantage is the inability to determine the temperature of the processors. But in contrast, there is a good computer scanning speed and the reliability of the utility.

performance test

This tool is slightly different from the previous options - this is a set of tests for evaluating PC performance. As a result of each test, the program collects characteristics that it compares with those of similar devices. The latest version of this utility contains 27 functions that differ in relation to a specific category. Several can be distinguished:

• For the processor - compression, encryption and calculation speed
• For a video card, which assesses the quality of displaying two- and three-dimensional graphics and animation, as well as compatibility with DirectX and its analogues
• For a hard drive, where you can test writing, reading and speed of information retrieval
• For disk drives
• For RAM

There are many more functions, in addition, the user can create five of his own tests. By the way, the program saves test reports in many standard formats from HTML to Docx. They can be sent by email, or pasted into any text editor and printed.

The ability to import tests into another application and insert them into the site code is also very remarkable.. It is important to note that PerformanceTest is only shareware, but it can be easily downloaded and activated on many file hosting sites. It works on all versions of Windows from XP to 10.

CrystalDiskMark

Another program designed to conduct tests, analyze the read and write speed of a hard drive. CrystalDiskMark uses test files ranging in size from 50 MB to 32 GB, and by running them, the utility reveals the average disk speed. To identify accurate performance indicators, it makes several checks at once, the number of which you personally specify before starting testing. In the settings section, you can choose the type of data, intervals between tests, queue sizes, and the number of threads.

The program is free, Russified and suitable for any version of Windows. It is quite small in size, so it downloads quickly and takes up almost no space.

CrystalDiskMark gives the results in a convenient way. Of course, the data on the average read and write speed of the “hard” is unlikely to be of interest to an amateur, but a professional can easily understand the reporting. By the way, the more tests the program conducts, the more average results you will get.

List of installed programs
Information about temperature sensors

To find out what hardware is inside or a laptop, special programs will help, they are also called utilities. There are a lot of them, consider the most popular ones.

AIDA64 (or "Everest")

AIDA64 (or "Everest") - providing information not only about hardware, but also about programs and fan characteristics and much more.

Everest, in addition to information about computer components and tracking their work, can also do tests (like SoftwareSandra). They are produced during the upgrade (modernization). There are several versions of the program (4). AIDA64 Extreme Edition is suitable for a home computer . You can download the program (Russian-language) from. The program is not free - you need to register it after 30 days (This "split" version is on trackers - checked. http://rutracker.org/forum/viewtopic.php?t=4749469) . Download the installation file and run it. After installation and launch, an interface appears.

Short video

Every year more and more programs for computer diagnostics are released. But even more is the number of users who buy a PC and want to make sure that the components, painstakingly found on the dusty shelves of online store warehouses, fully satisfy all their requirements. It is no less difficult to do without programs of this kind in the daily operation of a computer. Many of them allow you to not only diagnose problems, but also keep your PC under control.

There are a number of programs, the possibilities of which are expanding from year to year, while the product for an inexperienced user becomes complicated, and the price increases several times. There are also analogue programs that have a slightly less meager arsenal of features, but are worthless. We will get acquainted with the most polar representatives of both categories among users in this review.

AIDA64 is without exaggeration the most popular product for review and diagnostics of a personal computer in general. The program can provide the most complete information about any component of the working machine: components, programs, operating system, network connections and external devices. For many years of superiority in the market, it has acquired AIDA64 and a whole range of utilities for diagnosing the stability of the PC and testing its performance. Easy to learn thanks to a simple and friendly interface.

Everest was once a very popular computer hardware and software analyzer. It allows you to find out comprehensive information about the system, which would be very difficult to obtain otherwise. Developed by Lavalys, the program was a follower of AIDA32. In 2010, the rights to develop this product were purchased by another company. In the same year, the development of Everest itself was also discontinued, and AIDA64 was eventually introduced on its basis. But even after so many years, Everest is still relevant and loved by many users of the product.

SIW

System Info For Windows is a utility that provides the user with an easy-to-configure and operate tool that allows you to view detailed information on part of the PC hardware and hardware configuration, installed software, system components, and network elements. With its functionality, the SIW product competes closely with AIDA64. However, they also have differences. Although System Info For Windows cannot boast of such powerful PC diagnostic resources, it has a number of its own, no less useful tools.

System Explorer

The System Explorer utility is completely free and in its likeness is an analogue of the classic Windows task manager. It helps in real time to monitor the operation of the computer and manage its processes. An essential database is built into the utility, according to which you can check any of the processes running on the user's computer for the content of malicious information. The interface is correctly translated into Russian, divided into tabs, each of which is responsible for specific tasks. Understanding the operation of the System Explorer utility is not difficult even for an inexperienced user.

PC Wizard

PC Wizard is a powerful program that provides information about the operation of the motherboard, processor, video card and a number of other computer components. A feature of this product from a number of similar ones is a number of tests that allow you to determine the performance and overall performance of the system. The interface of PC Wizard is minimalistic and it is very easy to understand how it works. The program is widely known among users due to its free distribution. And although the developer has stopped supporting it since 2014, even today it can be a good helper in assessing the potential of a PC.

SisSoftware Sandra

The SisSoftware Sandra program is a collection of useful utilities that will assist in diagnosing the system, installed programs, codecs and drivers. Sandra also has the functionality of providing information about various components of the system. You can even perform diagnostic operations on devices remotely. The software product, with such a large functionality, is completely easy to use, which was achieved thanks to an intuitive interface, as well as high-quality Russian translation. SisSoftware Sandra is distributed according to a paid model, but you can evaluate all its advantages during the trial period.

3DMark is owned by Futuremark, one of the major players in the test suite market. They are not only visually very attractive and varied, but also always give a stable, repeatable result. The company's close cooperation with world manufacturers of processors and graphic cards allows us to competently improve our product. The tests included in the 3DMark package are used both to test the strength of weak machines, like laptops, and for the most advanced and powerful PCs. There are a number of tests for mobile platforms, for example, and that allows you to compare the real graphics or computing power of a smartphone.

No matter how powerful and perfect the components of modern computers are, their owners are still trying to improve, strengthen or overclock something. A good assistant to them in this will be the SpeedFan program, which, in addition to providing information on the account of the entire system, will also allow you to edit some characteristics. Skillfully using this product, you can optimally adjust the operation of coolers if they do not cope with their task of cooling the processor and motherboard, or vice versa, they start to work actively when the temperature of the components is still in the optimal state. Only experienced users will be able to fully work with the program.

OCCT

Even an experienced Windows user may sooner or later encounter an unforeseen problem that causes a computer to malfunction. The cause of the problem may be overheating, overloading or a mismatch of components with each other. To identify them, you need to use specialized software. It is to the category of such products that OCCT is referred. Thanks to a series of tests of PC components, the program can detect sources of malfunctions or prevent their occurrence. There are also real-time system monitoring capabilities. The interface is non-standard, but convenient, besides Russified.

S&M

A small and completely free program from a domestic developer is a set of tests for loading computer components. The ability to monitor the testing process allows you to track possible problems in real time regarding overheating or insufficient power supply, as well as determine the overall performance of the processor, RAM and the speed of hard drives. The simple interface of the program and a detailed description of the test settings will allow even a beginner to test the PC for strength.

In order for the computer to function reliably and smoothly, it is necessary to diagnose all possible failures and malfunctions in its operation in time. The programs presented in the review can help with this. It is difficult to choose one product for yourself, even one that tries to be as versatile as possible. Each tool has both its advantages and disadvantages, but they all cope equally well with their priority tasks.

In order to measure the performance of a computer using tests, it is not necessary to download any third-party applications and utilities.

It is enough to use the resources already built into the operating system.

Although for more detailed information, the user will have to find a suitable program.

Based on the test results, one can draw conclusions which of the parts of a PC or laptop need to be replaced before the rest - and sometimes just understand the need to buy a new computer.

The need for verification

Performing a computer speed test is available to any user. The check does not require any specialized knowledge or experience with certain versions of Windows OS. And the process itself is unlikely to take more than an hour.

Reasons why you should use the built-in utility or third-party application include:

• unreasonable slowdown of the computer. Moreover, not necessarily the old one - a check is needed to identify problems with new PCs. So, for example, the minimum results and indicators of a good video card indicate incorrectly installed drivers;
• checking the device when choosing several similar configurations in a computer store. Usually they do this before buying laptops - running a test on 2-3 devices that are almost identical in parameters helps to find out which one suits the buyer better;

• the need to compare the capabilities of the various components of a progressively upgraded computer. So, if the HDD has the lowest performance value, then it should be replaced first (for example, with an SSD).

According to the results of testing, which revealed the speed of the computer performing various tasks, you can detect driver problems and incompatibility of installed devices. And sometimes even poorly functioning and failed parts - for this, however, you will need more functional utilities than those that are built into Windows by default. Standard tests show a minimum of information.

Checking by means of the system

You can test the performance of individual computer components using the built-in capabilities of the Windows operating system. Their principle of operation and information content are approximately the same for all versions of the platform from Microsoft. And the differences are only in the way of launching and reading information.

Windows Vista, 7 and 8

In the 7th and 8th versions of the platform, as well as Windows Vista, the performance counter of computer elements can be found in the list of basic information about the operating system. To display them on the screen, just right-click on the "My Computer" icon and select properties.

If testing has already been conducted, information about its results will be available immediately. If the test is running for the first time, it will have to be launched by going to the performance test menu.

The maximum score that Windows 7 and 8 allow you to get is 7.9. It’s worth thinking about the need to replace parts if at least one of the indicators is below 4. For a gamer, values ​​above 6 are more suitable. Windows Vista has a better indicator of 5.9, and a “critical” one of about 3.

Important: To speed up performance calculations, you should turn off almost all programs during the test. When testing a laptop, it is advisable to turn it on to the network - the process noticeably consumes battery power.

Windows 8.1 and 10

For more modern operating systems, finding information about computer performance and starting its calculation is no longer so easy. To run a utility that evaluates system parameters, should take these steps:

1Go to operating system command line(cmd via menu "Run", called by pressing the keys simultaneously Win + R);

2Enable evaluation process, leading the team winsat formal –restart clean;

3Wait for completion of work;

4Go to folder Performance\WinSAT\DataStore located in the Windows system directory on the system drive of the computer;

5Find and open a file in a text editor "Formal.Assessment(Recent).WinSAT.xml".

Among a lot of text, the user must find WinSPR block, where approximately the same data is located that is displayed on the screen and Windows 7 and 8 systems - only in a different form.

Yes, under the name SystemScore the general index calculated by the minimum value is hidden, and MemoryScore, CPUScore and GraphicsScore stand for memory, processor, and graphics card metrics, respectively. GamingScore and DiskScore- performance for the game and for reading / writing the hard disk.

The maximum value for Windows 10 and version 8.1 is 9.9. This means that the owner of an office computer can still afford to have a system with numbers less than 6, but for the full operation of a PC and a laptop, it must reach at least 7. And for a gaming device - at least 8.

Universal way

There is a way that is the same for any operating system. It consists in launching the task manager after pressing the Ctrl + Alt + Delete keys. A similar effect can be achieved by right-clicking on the taskbar - there you can find an item that launches the same utility.

You can see several graphs on the screen - for the processor (for each thread separately) and RAM. For more details, go to the "Resource Monitor" menu.

From this information, you can determine how heavily loaded individual PC components. First of all, this can be done by the percentage of loading, secondly - by the color of the line ( green means normal operation of the component, yellow- moderate red- the need to replace the component).

Third Party Programs

With the help of third-party applications, it is even easier to check the performance of your computer.

Some of them are paid or shareware (that is, requiring payment after the end of the trial period or to increase functionality).

However, these applications also conduct testing in more detail - and often give out a lot of other useful information for the user.

1.AIDA64

As part of AIDA64, you can find tests for memory, cache, HDDs, SSDs, and flash drives. And when testing the processor, 32 threads can be checked at once. Among all these pluses, there is a small drawback - you can use the program for free only during the "trial period" of 30 days. And then you have to either switch to another application, or pay 2265 rubles. for a license.

2. SiSoftware Sandra Lite

3.3DMark

4. PC Mark 10

The application allows not only to test the operation of computer elements, but also to save the results of tests for further use. The only drawback of the application is the relatively high cost. You will have to pay $30 for it.

5. CINEBENCH

The test images consist of 300,000 polygonal images that add up to more than 2,000 objects. And the results are given in the form PTS indicator - the larger it is, the more powerful the computer. The program is distributed free of charge, which makes it easy to find and download it on the network.

6.ExperienceIndexOK

Information is displayed on the screen in points. The maximum number is 9.9, as for the latest versions of Windows. It is for them that the work of ExperienceIndexOK is intended. It is much easier to use such a program than to enter commands and search the system directory for files with results.

7. Crystal DiskMark

To test a disk, select a disk and set the test parameters. That is, the number of runs and the size of the file that will be used for diagnostics. After a few minutes, the average read and write speed for the HDD will appear on the screen.

8 PC Benchmark

After receiving the test results, the program offers to optimize the system. And after improving the work in the browser, a page opens where you can compare the performance of your PC with other systems. On the same page, you can check if the computer can run some modern games.

9.Metro Experience Index

10. Pass Mark Performance Test

conclusions

Using various ways to check the performance of your computer allows you to check how your system is performing. And, if necessary, compare the speed of individual elements with the performance of other models. For a preliminary assessment, such a test can also be carried out using the built-in utilities. Although it is much more convenient to download special applications for this - especially since among them you can find several fairly functional and free ones.

Checking (diagnosing) a computer or laptop- a mandatory operation when overclocking their components. Residents who do not use the possibility of overclocking may need to test their computer when buying a new system. This is especially true when the "iron" is taken "from the hands", i.e. no special guarantee. In this case, it is necessary to diagnose processor, video card, memory etc. to make sure computer or laptop stability under load.

Computer stability test usually performed by long-term load of its components. For each of the checked nodes, they usually use their own diagnostic program. It would seem that you can run one resource-demanding game and the processor, video card and memory will be automatically checked, but this is not so. Typically, games put a lot of stress on the graphics system, and the CPU may not be used to its full capacity. As a result, the CPU was left without testing under maximum load. That is why for them there are independent diagnostic programs.

Please note that testing (of any component) should take as long as possible: a couple of minutes is usually not enough even to simply warm up up to the maximum temperature of the diagnosed piece of iron. One can be more or less sure of stability only after 10-15 minutes of operation of the unit at the maximum temperature. Those. after running diagnostic program, it is necessary to monitor the temperature of the component being checked, and after its temperature has stopped rising, it needs at least 10-15 minutes of its operation without failures. It usually takes up to 5 minutes to warm up.

How to check the processor.

Previously, the site already posted information about, which creates the maximum load on the CPU and warms it up well. This is one of the best utilities of its kind. In principle, there are many similar programs that, in addition to the stability test, are also utilities from the “benchmark” section for evaluating CPU performance.

Quite suitable for checks and a modern archiver WinRAR, which has a built-in function for evaluating the performance of the computer's computing capabilities and absence of errors while ("Tools" - "Benchmark" or "Alt + B"). In addition, it also loads the memory well, so in case of unstable operation, the error counter will be different from zero. Now many archivers have a similar benchmarking function - including the popular and quite good one. archiver "7-Zip".

CPU temperature monitoring under maximum load may reveal such a problem as insufficient cooling. In rare cases, the maximum allowable temperature reaches 95 degrees. Usually somewhat lower. So if you saw the readings of the corresponding sensors close to these values, you should replace cooling system CPU (in the best case, replacing the thermal paste under the radiator is enough).

Video card check.

Checking the video card- the most spectacular stage computer diagnostics or laptop. Unlike boring tables in CPU test utilities, at this stage, the monitor will please the eye of computer game lovers with all sorts of fantastic characters, landscapes, or just beautiful abstract figures, which will require all the power of the video card.

One of the most popular programs for checking the video card - "FurMark". In addition to the fact that the utility does an excellent job with its tasks, it takes up very little disk space. Those who are unable to remember the name of this program can always find it in a search engine for the query " hairy bagel", since the picture on the monitor looks like it during the diagnostics. By the way, to monitor the temperature of the graphics chip, memory frequencies and the GPU itself, there is no need for third-party utilities - "" displays this data on the screen on top of the "donut". It was this software product that we used when evaluating temperature mode of the video card "" from Asus. The undoubted advantage is that FurMark is a free program, which can be downloaded from the official website.
