Why does Windows computer automatically power off and restart?

1. The power supply is one of the biggest suspects causing the system to automatically restart.

Inferior power supply cannot provide enough power. When the number of devices in the system increases, the power consumption changes. If the power supply is too large, the output voltage of the inferior power supply will drop sharply, eventually causing the system to work unstable and automatically restart. Excessive voltage fluctuations may also cause damage to hard drives and other equipment.

2. Memory problems will also cause system restart

The probability of system restart due to memory errors is relatively high. In addition to ruling out poor contact between the memory module and the slot, you should suspect that there is a quality problem with the memory itself. In addition, setting the CL value of the memory too small can also cause memory instability and cause the system to automatically restart.

3. Excessive fluctuations in the power grid voltage will also cause the system to restart

In addition, if your computer shares a power strip with high-power-consuming appliances such as air conditioners and refrigerators, when these appliances are started, , the voltage supplied to the computer will be greatly affected, which often manifests itself as a system restart. The best solution is to equip the computer with a UPS to provide power, and be careful not to connect other electrical appliances to the UPS.

4. Poor contact of the power socket

After the power socket is used for a period of time, the elasticity of the reed will change. Slowly lost, resulting in poor contact between the plug and the reed, constant changes in resistance, and fluctuations in current, the system will naturally become unstable. Once the current does not meet the minimum requirements for system operation, the computer will restart. The solution is to buy a good socket with acceptable quality.

5. The temperature when the system is running is too high

At this time, you should check whether the CPU fan is operating normally and whether the heat dissipation conditions are good. Today's motherboards have the function of detecting CPU and system temperature in the BIOS through specialized control chips. If the temperature is found to be too high, the fan should be replaced or added.

6. Hardware compatibility issues

are generally caused by the compatibility of the motherboard and the memory module, but the author has also encountered examples of graphics cards causing the system to continuously restart. After hardware modifications, the shield This fault disappeared only after disabling the AGP 4× function of the graphics card. Therefore, when you buy new accessories, it is best to try them before buying them.
