How to use Win7 computer graphics card fault detection software

1. Find the root cause of the fault through the blue screen information

If your computer often encounters blue screen problems, it is recommended to search for the information provided on the screen when the blue screen is displayed. The blue screen often shows the crashed driver or the one it encounters. The type of error message, which tells us the problem intuitively, most of the blue screen problems that are encountered in Windows today are most likely caused by hardware failures (memory is more common).

For example, if you find that the blue screen information is displayed due to the blue screen caused by the driver of “NV4_disp.dll”, you will find that this is the NVIDIA graphics driver after Google or Baidu search, so that you only Need to update the N card driver, if this problem still occurs, it is likely that your graphics card is broken.

2, check the SMART status of the hard disk

The hard disk has a built-in S.M.A.R.T. (self-monitoring, analysis and reporting technology) function. With this feature, the drive will self-analyze and detect failures and alert you before it is completely out of work. But this is not perfect, so your hard drive may crash, even though SMART says it's all trouble-free, but it's still very swimming to some extent.

If you see any kind of "SMART error" message, your hard drive will be malfunctioning. You can use the SMART analysis tool CrystalDiskInfo to view the SMART health status information reported by your hard drive.

3, memory test

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

To test your memory and see if it works, it is recommended to use the built-in memory diagnostic tool in Windows. Start menu, directly search for "Windows Memory Diagnostics" tool, after running, the memory diagnostic tool will write data to each area of ​​your RAM and then read and test to ensure that all RAM is working properly.

4, check how hot the computer is

How hot is your computer? If the computer overheats, it will cause the computer to blue screen, the system crashes and suddenly shuts down automatically. Computer overheating is often caused by excessive dust inside the computer, poor ventilation, fan shutdown, etc. When the computer is not well ventilated, running large programs, such as games, is more likely to cause the computer to automatically shut down, crash and blue screen.

You can see the temperature information of each part of the computer in the bios of the computer. Of course, you can also use some software to view it in the system, such as SpeedFan, AIDA64, etc. If the computer finds that the temperature is too high, it is recommended. Disassemble the computer and put it into dust. After cleaning, you will find that the computer runs much faster and won't get stuck so often.

5, stress test the CPU

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

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

6. Stress test the graphics card

Your graphics card can also be stress tested. For example, if your graphics driver crashes while playing a game, the game itself crashes, or you see strange graphics clutter, you can run a graphical benchmarking tool, such as 3DMark. The benchmark will stress test your graphics card. If it overheats or crashes under load, you will see graphics problems, crashes or blue screens while benchmarking.

If the benchmark works fine, but you have problems playing some games, maybe it's just because the game itself might have problems.

7. Diagnosing by replacing hardware

Not every hardware problem is easy to diagnose. If you have a bad motherboard or power supply, their problem may only be detected by matching it with other components. It is more difficult to distinguish 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 graphics card might cause your computer to have a blue screen, then pull out your computer's graphics card and replace it with a new one. If everything works smoothly, chances are that your previous graphics card is bad.

For average home users, there is not so much hardware to replace detection, but it is the best way to solve problems.
