Win7 computer graphics card fault detection software how to use

1, through the blue screen information to find the source of the fault

If your computer often encounters a problem with a blue screen, it is recommended to search the screen when the information provided, blue screen often shows the crash of the driver or it encountered the wrong type of information, it can be very intuitive to tell us the problem, now in Windows met most of the blue screen problems are likely to be caused by a hardware failure ( Memory is more common).

For example, if you find that blue screen information is displayed as a result of the "Nv4_disp.dll" drive, after you search Google or Baidu, you will find that this is Nvidia's graphics driver, so you only need to update the N-card driver, if this problem still occurs, it is likely that your video card is broken.

2, check the hard drive smart status

The hard drive has a built-in s.m.a.r.t. (Self-monitoring, analysis and reporting technology) function. With this feature, the hard drive will self analyze and detect the failure and warn you before it is completely out of work. But it's not perfect, so your hard drive may crash, even if Smart says everything's all right, but it's still pretty much swimming.

If you see any kind of "smart error" message, your hard drive will fail. You can use the Smart Analysis tool Crystaldiskinfo to view the smart health status information reported by your hard drive.

3. Memory Test

A memory failure can cause a variety of problems. If because of a failure, the computer writes data to memory RAM but the RAM returns different data, you may see application crashes, blue screen, and file system corruption.

To test your memory and see if it works properly, it is recommended that you use the built-in Memory Diagnostics tool in Windows. Start menu, search the Windows Memory Diagnostics tool directly, and after running, the Memory Diagnostics tool writes the data to each area of your RAM and reads it for testing to make sure all the RAM is working properly.

4. Check how hot the computer is

How hot is your computer? computer overheating can cause computer blue screen, system crashes and sudden automatic shutdown. Computer overheating is often because of excessive dust inside the computer, poor ventilation, fan stop running and other causes, when the computer ventilation is not smooth, running large programs, such as games, more easily caused by computer automatic shutdown, crash and blue screen.

You can access the computer BIOS to see the computer parts of the temperature information, of course, you can also use some software in the system to view, such as SpeedFan, AIDA64, etc., if the computer found that the temperature is too high, it is recommended to take the computer into dust cleaning, After cleaning up you will find that the computer is running a lot faster, and it won't be easy to get stuck in so often.

5, the CPU for the pressure test

You can use a tool like Prime95 to give your CPU a stress test. Such a tool will force your computer's CPU to perform calculations, but not allow it to stop, let it work at full capacity and generate heat. If your CPU gets too hot, you start to see errors or system crashes.

Users who like CPU overclocking can use Prime95 to stress test their overclocking settings-if Prime95 encounters an error, it restricts overclocking to ensure that the CPU is running at a lower and more stable temperature. This is a good way to check if your CPU is stable under load.

6, the graphics card for pressure testing

Your graphics card can also be tested for stress. For example, if your graphics driver crashes when you play a game, the game itself crashes, or you see strange graphics disorders, you can run a graphical benchmark tool, such as 3DMark. The benchmark will give you a stress test on your graphics card, and if it is overheating or crashes under load, you will see a graphics problem, crash, or blue screen in the benchmarking test.

If the benchmark is working correctly, but you are having trouble playing some games, it may be because the game itself may be problematic.

7, through the replacement of hardware to diagnose

Not every hardware problem is easy to diagnose. If you have a bad motherboard or power supply, their problem may be detected only by pairing with other components. It is more difficult to tell which parts directly, unless you replace them completely.

The best way to determine if a component is faulty is to replace it. For example, if you think your video card may cause your computer to be a blue screen, unplug your computer's video card and replace it with a new video card. If everything works smoothly, it's likely your previous video card is bad.

For ordinary home users, there is not so much hardware to replace detection, but it is the most ideal way to solve the problem.
