Computer restarts automatically

During the use of the computer, many friends have encountered the situation that the system restarts automatically for no reason. In fact, there are many causes of computer restart, including the following hardware reasons:

1. Power supply is one of the biggest suspects of automatic system restart. Poor power supply cannot provide enough power. When the number of devices in the system increases and the power consumption increases, the output voltage of poor power supply decreases sharply, leading to unstable system operation and automatic restart. High voltage fluctuations may lead to damage to hard disks and other devices.

2. Memory problems may also cause system restart. Memory Errors cause a relatively high probability of system restart. Excluding poor contact between memory stick and slot, we should suspect that the memory itself has quality problems. In addition, setting the CL value of the memory too small will also cause memory instability, resulting in automatic system restart. A simple solution: If SDRAM is used, set the CL value to 3. if DDR is used, set the CL value to 2.5. If the main board of the VIA chipset is used, we recommend that you disable the memory staggered execution function.

3. If the grid voltage fluctuates too much, the system will restart. In addition, if your computer shares a plug-in board with large power-consuming appliances such as air conditioners and refrigerators, the voltage supply to the computer will be greatly affected when these appliances are started, usually, the system restarts. The best solution is to assign a dedicated UPS power supply to the computer. Note that other appliances will not be connected to the UPS again.

4. Poor contact with power outlets. After the power outlet is used for a period of time, the elasticity of the reed gradually loses, resulting in poor contact between the plug and the reed, constant changes in resistance, and fluctuating current, the system will naturally be unstable, once the current does not meet the minimum requirements for system operation, the computer restarts. The solution is to purchase high-quality sockets.

5. The temperature during system operation is too high. In this case, check whether the CPU fan runs properly and whether the cooling conditions are good. The current motherboard uses a dedicated control chip to detect CPU and system temperature in the BIOS. If the temperature is found to be too high, you should repair or replace the fan in time.

6. hardware compatibility issues. This is generally caused by the compatibility between the motherboard and the memory stick, but I have also encountered examples of constantly restarting the system due to compatibility issues between the video card and the motherboard. So when you buy new accessories, it is best to have enough knowledge of it.
