TOP 10 programs for diagnosing computer malfunctions

Nowadays, it is becoming more and more difficult to keep your home computer in good condition, especially if component graders have not been produced for a long time, since all new versions of programs installed on the PC overload its system and do not allow it to work normally quickly.

In today's review, we decided to collect all the most convenient programs for PC diagnostics in Russian. Let's say that the best programs are paid, but there are trial versions that will give you a lot of opportunities and use them a couple of times and solve your problems.

This software will help diagnose and find all system faults, as well as problems with the video card, processor, RAM, hard drive, etc. All the utilities presented in the rating are based on our experience of testing them on our computers.

Review of programs for PC diagnostics

Advanced System Care download

Advanced System Care Free is a utility for high-quality automation, normalization and increasing the speed of the processor operating system.

iObit Corporation's product includes a set of free mechanisms and add-ons for high-quality modernization subsystems, in-depth diagnostics and the fight against spyware, thanks to which the software easily competes even with commercial analogues.

AIDA64 Extreme

As the successor to the famous EVEREST, AIDA64 is the most powerful utility today for comprehensive computer diagnostics. In addition to the information stored in the BIOS memory, Aida provides statistical data from the Internet and other useful information regarding the selected device. It contains many different tests to check performance and stability under load, and to compare with other models. AIDA64 Extreme is a shareware product, since the user is given only 30 days for trial use with reduced capabilities.

The usefulness of AIDA64 Extreme is difficult to overestimate, because it is one of the few programs that provides comprehensive information about all the characteristics of each component device, and even each chip on the board. By installing it on your PC, you will learn about all available frequency and temperature indicators, voltage at device pins, cooler rotation speed, power consumption, etc. In addition to the hardware component, Aida 64 displays information about the operating system and installed components (for example, DirectX).

In Test mode, AIDA64 Extreme tests and compares your configuration with other devices from its own database, thus creating a rating. It is worth noting the ability to check network devices and connections over a local and global network.

Computer Accelerator download

Together with competing software of this gradation, the product we are studying demonstrates an unimaginable acceleration of PC performance, extremely high-quality adjustment and an impressive set of tools for identifying any interruptions and malfunctions in the system.

3DMark

At the moment it is difficult to find a better and more beautiful tester than 3DMark from Futuremark (now UL Benchmark). Its tasks include checking the performance of the central processor + video card combination. The developer offers several versions of the benchmark: a free Basic Edition with reduced capabilities, an Advanced Edition with a large number of tests and settings, and a Professional Edition (available for commercial use).

The main feature of this tester is the increased requirements for computer hardware, so even on mid-level systems the user may be surprised by the low number of points received. The second “calling card” of 3DMark is the colorful, well-designed three-dimensional scenes that simulate games during testing. Tests are carried out not only with qualitative, but also with quantitative scenes, which put more load on the CPU. 3DMark supports all modern graphics processing technologies, including DirectX 12 and NVIDIA RTX and DLSS.

At the end of the test, you will see the result in the form of points scored for the system as a whole and for each device separately. You can publish your result and compare it with others in a rating created by other users.

Advantages:

• the benchmark loads the system 100% without causing breakdowns;
• benchmark tester for high-performance systems;
• beautiful 3D models and scenes;
• there is a free version of 3DMark Basic Edition;
• intuitive interface.

Flaws:

• there is no Russian language in the demo version settings;

A small program that scans the PC hardware configuration. This is necessary if you want to update your computer components and avoid compatibility problems:

Checking the computer's health - "Performance Monitor"

Like earlier versions of the operating system, Windows 10 has System Monitor, only now it's available as an app. Once launched, look at the sidebar. Under Monitoring Tools you should see System Monitor:

By default, the monitor only displays the "% CPU Load" parameter. It shows how much the processor is currently being used. But you can add more counters, such as disk usage, power, paging file size, search index size, and other metrics that are important to check your computer's health.

How to diagnose your computer yourself using the Reliability Monitor

Stability Monitor is a hidden tool that has been around since the days of Windows Vista, but many have never even heard of it. It is located in the control panel in the “System and Security” section - “ - “Show stability log”:

Here you will see a timeline of events and errors that occurred during a given period of time. The blue line is a rating (on a scale of 1 to 10) of how stable the operating system is over time.

If something often breaks down, you should look at the stability monitor: select the error and click “Check for a solution”.

There is no need to pay for the utility; the developer only accepts donations.

The main quality of HWiNFO is its stability on weak systems with outdated versions of Windows. This software will run even on Win XP, not to mention modern “tens”. The second advantage is detailed reporting on the state of the PC at the time of testing and the provision of detailed information about its parameters. A simple search for each device is provided by a hierarchical structure of icons with a description on the left side of the window. The available data can be easily saved into a test file using the “Save Report” button. In addition to checking your computer, HWiNFO has a routine for updating the motherboard BIOS and device drivers.

The HWiNFO software interface is designed in the familiar Windows style and is easy to use. At the top of the window there is a panel with icons for the most frequently used functions. The “Program” tab has a large number of settings for driver verification and management modes.
