Why does my computer crash or restart when playing big games?

For some players who like to play 3D games, if it is a painful thing to freeze frequently while playing 3D games, hehe, here I will summarize the common causes of such failures.

1 Problems with the graphics card itself. (1) Video memory is damaged. If the graphics card's video memory is damaged, this kind of phenomenon is very likely to occur, even if it doesn't crash, it will frequently report errors after playing 3D games for a while, and in this case, it's best to replace a good graphics card with a replacement method to try it.

2) The circuit or chip of the graphics card itself is damaged, resulting in a failure, so try to solve it by replacing it.

2 The voltage of the AGP slot is insufficient. The reason is that the voltage is unstable, so that when playing 3D games, it may instantly cause insufficient power supply to the AGP slot and cause a crash, so you should first check whether your power supply is enough or whether the power supply line is stable, or you can try to increase the voltage of AGP in the BIOS, generally increase it, but not too high, otherwise it will be very dangerous.

3.Graphics card workmanship materials and compatibility issues. Some miscellaneous or small and medium-sized brands of graphics cards will greatly reduce the electrical compatibility of the graphics card if the materials are insufficient, which is manifested as when the 8X graphics card runs at 8X, which will cause frequent crashes in 3D games, and when the AGP is adjusted to 4X in the BIOS, it will be no problem, this is because 8X has high requirements for the electrical compatibility of the graphics card, and it is easy to have problems if the materials are not well made.

4.Heat dissipation issues. Check whether the CPU temperature is normal in the BIOS, and then check whether the heat dissipation of the graphics card is abnormal.

5.System software issues. (1) Check whether your motherboard patch and graphics card driver are correct, whether the graphics card driver is damaged, if there is a crash problem, try to change a motherboard patch or graphics card driver, note that it is not the latest or the best, try to play the driver or patch in the disc that comes with the hardware.

2) Check to see if the DirectX file is corrupt or the version is too low, and run the DirectX diagnostics with the dxdiag command in Runtime. (3) Check whether hardware acceleration is enabled. (4) Clean up the junk files of the system, and try to reinstall the system if it really doesn't work.

6 If it is an integrated graphics card, the memory should also be checked, because the video memory used by the integrated graphics card is divided into a part of the memory to the integrated graphics card chip.

The common causes of failures and solutions are the above, when the failure occurs in line with the principle of soft and hard step by step, I believe you will find out the cause.
