The computer suddenly shuts down what's going on

　　Automatic Shutdown Troubleshooting Method:

　　1 There may be a problem with the BIOS setup , enter the BIOS to restore the default settings or the motherboard of the battery to take out, reverse-button discharge, and so on 5 minutes in reverse loading can be. The purpose of the BIOS setting restores defaults, excluding BIOS thermal preset automatically restart or shutdown phenomenon.

　　2. Memory reason. when the memory and the motherboard slot contact loose can also cause the computer to shut down automatically, it is recommended to check the memory and the motherboard plugged in. Then use the elimination method, check memory, video card, CPU CPU fan, motherboard and so on.

　　3. Heat dissipation is not good. due to the effect of weather temperature or the CPU fan is not enough to cause the system overheating, resulting in automatic shutdown of the computer, it is recommended to check the system temperature is normal. By cleaning the dust of the parts in the computer host to troubleshoot the problem. Dust is also can cause computer automatic shutdown failure of one of the factors, dust can cause parts aging, pin oxidation, poor contact and short-circuit and so on. For the dust caused by these failures, the general use of cleaning method is more effective

　　4. Software factors. if the computer in the use of a certain application sequence software occurs automatically shutdown, then the automatic shutdown failure may be caused by this sequential software will generally uninstall the program software. As a result of viruses or trojans caused by computer shutdown also abound especially recently popular shock wave, the virus will lead to the system after the restart and shutdown. If you use the Windows 2000 or Windows XP system, it is recommended that you use antivirus software after the shock wave on the timely patch, the general problem can be solved.

　　5. Power supply problem. the lack of power supply is also an important factor in computer automatic shutdown, power quality is poor, aging or power too small, can not meet the power requirements of computer accessories, can be replaced by high-power high-quality power supply, the problem exists very little possibility.

　　6 Check the motherboard, motherboard aging, capacitor failure or slurry, motherboard power pins, motherboard and chassis backplane and other short circuit may cause automatic shutdown, the motherboard can be removed from the chassis inspection or testing, and then check the CPU fan rotation and CPU temperature is normal, and then check the CPU Fan heatsink Bottom silicone is dry, if dry, the CPU fan on the silica gel clean, and then besmear the good silicone can be. If the fan is not normal, replace the CPU fan.

　　7 May be playing a large game caused the CPU overheating , and the CPU fan cooling will cause the computer automatically shutdown. If it is and often occurs automatically shutdown failure, it is recommended that the replacement of a high quality CPU cooling fan, the bottom of the fan heatsink is dry, if dry, the CPU fan on the silica gel clean, and then besmear the good silicone can be. If it is the game software caused by automatic shutdown, please unload load.

　　8. The problem with the graphics card itself. 1 video memory is damaged. This kind of phenomenon is very easy to happen if the display of the video card is damaged. Even if you do not crash the 3D game after a period of time will also frequent error, this situation is best replaced by the replacement of a good video card to go to try on the line of 2 graphics card itself or chip damage, resulting in failure, this is also a replacement method to try to solve.

　　9. The AGP slot voltage is insufficient. The reason is that the voltage is not stable, so that playing 3D games may instantly cause an AGP slot power supply is not enough to cause the panic, so you should first check your power supply power or whether the power line is stable, or you can try to increase in the BIOS of the AGP voltage, the general increase of 0.1V can, But it can't be too high, or it's going to be dangerous.

　　10. System software problems. 1 Check your motherboard patch and graphics driver is correct, the driver of the graphics card is damaged, if there is a crash problem first try to change a motherboard patch or graphics driver, attention is not the latest is the best try to play with the hardware attached to the disc in the drive or patch. 2 to see if the DirectX file is corrupted or version is too low, run the input dxdia G command to run the DirectX Diagnostic order to see. 3 to see if the hardware acceleration to open the 4 clean up the system of garbage files, it is not really good to try to reinstall the Department
