Common causes and solutions of computer automatic shutdown

Mainly do a few checks. First check the power supply is not enough, recently is not what new hardware added, if it is possible that the power supply voltage is not enough, need to replace the power supply. Second, check the motherboard battery is dead, the motherboard of the battery if the power may also cause this situation, this time need to remove the motherboard battery, or to the computer repair shop to recharge. Finally make sure you don't kick the power cord or the host line yourself. Just look and check if your computer's plug voltage is sufficient. Hardware parts have been tested, if not not, start with the software. Check if you have been poisoned, whether there is software incompatible and so on.

The problem of heat dissipation, we all know CPU, graphics, hard disk, motherboard temperature is too high to cause the computer is always automatic shutdown, to achieve the purpose of protecting the computer, we can use a class of software to detect the temperature, if the temperature is too high, we have to see if the chassis is too dusty, appropriate cleaning up, By the way also can check whether the jumper contact is not real, the memory strip loose and so on.

Specific Solutions

1, automatic shutdown troubleshooting methods:

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, etc. may cause automatic shutdown, can remove the motherboard from the chassis check or test, and then check the CPU fan rotation and CPU temperature is normal, and then check the CPU fan heatsink bottom silicone is dry, If it dries, clean the silicone on the CPU fan and then paint the silicone again. 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. If the display of the graphics card is very easy to occur this kind of phenomenon, even if not panic play 3D game after a period of time will also frequent error, this situation is best to replace the way to change a good video card up to try on the line

2 the circuit or chip of the video card itself is damaged, which leads to the failure, so it is tried to solve with the substitution method.

9. The AGP slot voltage is insufficient. The reason is that the voltage is not stable, so that playing 3D game may instantly cause the AGP slot power shortage and caused the panic, so you should check your power supply power is enough or the power line is stable, or you can try to adjust the BIOS in the AGP voltage, the general height of 0.1V can be adjusted, but not 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 look at the hardware to accelerate whether to open 4 clean up the system of garbage files, it is not really good to try to reinstall the system.

11. Computer suddenly automatic shutdown reason

1, the computer at home ran the shutdown software when the shutdown Wangding, and made the following settings: "Operation Settings"-"Every Day"-"23:59:59"-"Shut down the computer", and set the "shutdown before" no reminders, so every time the computer suddenly shut down automatically.

2, the computer suddenly automatic shutdown solution: It is recommended to set the 1 minutes before the shutdown prompts, the computer will not suddenly automatically shutdown situation.

3, of course, you can also set a specified time to execute a specific program: 2012-3-16 23:59:59 to execute a program.
