"Every time I play a 3d game, my computer crashes! I am depressed dead! Can someone help?" -- Williams

For some players like to play 3D games, it's a very painful thing if the computer crashes frequently when they playing 3D games. Well, here I summarize the causes and solutions for such failures.

1. Video card problems - Cause of computer crashes when playing 3d games

(1) Video card is damaged. If the video card is damaged, this phenomenon will easily happen. Even if it does not crash when playing 3D games, it will frequently prompt errors after playing for a while. If this happens, you'd better replace the video card with a good one and have a try.

(2) The line or the chip of the video card is damaged, leading to failures. You can also solve it with a substitution like above.

2. Voltage of AGP slot is insufficient - Cause of computer crashes when playing 3d games

This reason is voltage instability which causes instant power supply shortage of AGP slot and makes the computer crash. Therefore, you should first check whether the power or the power lie is stable enough or not, or you can try to raise the AGP voltage. Generally raise 0.1V. You should not raise it too high, otherwise it will be very dangerous.

3. The video card's material and compatibility issues - Cause of computer crashes when playing 3d games

Some video card of no-name brand or small and medium brand is made insufficient in material which reduces the compatibility. When running the 8X video card at 8X will result in frequent crashes when playing 3D games. However, after you adjust the AGP in bios to 4X, the problem can be solved. This is because that 8X requires a higher electrical compatibility. If the materials is not good, this problem can easily rises.

4. Heat dissipation problem - Cause of computer crashes when playing 3d games

Check the CPU temperature and see if it is normal, and then check the heat dissipation of the video card to see if it is abnormal.

5. System software problems - Cause of computer crashes when playing 3d games

(1). Check your motherboard patch and video card driver to see if they are the right ones. If the computer crashes, you can replace the motherboard patch and video card driver with the best and newest ones. You can install the driver or patch in the disc which attaches to the hardware.
Tips: If your driver disc is missing and you don't know where to download drivers with the latest version, you can use a driver updater like Driver Robot, click here to free download it. If you don't know how to use it, here is the guide: how to use driver robot.

(2). Check the directx file to see if it is damaged or outdated -- you can type "Dxdiag" in the "Run" open box to run the directx diagnostic program.

(3). See if the hardware acceleration is open.

(4). Clean up system junk files. If it still has the problem, try to reinstall the system.

6. Less video memory - Cause of computer crashes when playing 3d games

If it is integrated video card, you need to check the memory. For the video memory is divided from the memory.
