Why does the computer always restart automatically?

1. The computer automatically restarts, 60% of which is caused by the power supply problem: the leakage of the large capacitor of the power supply is caused by the lack of power supply, which should be solved immediately after replacing the battery; 2. Poor contact between the memory stick and the memory on the motherboard: you can pull out your current memory, then rub it back and forth with an eraser where the golden finger is located (that is, where there is copper), blow off the dust, and then plug in the wire or plug it back into the memory stick; 3. There is something wrong with your CPU fan, or the clip of the radiator is loose: the CPU fan is stuck and the CPU cannot dissipate heat. When the temperature reaches the set temperature of the motherboard, the motherboard will start protection, automatically restart, and the electric fan can be replaced; 4. The video memory integrated block of the video card has virtual welding, which leads to poor contact with the motherboard after booting: welding the video memory can be solved, or changing the video card. 5. The voltage is unstable, which can't reach the starting voltage and exceeds the specified voltage: the computer will be restarted, and a UPS, also called an uninterruptible power supply, can be stabilized for 30 minutes to save data; 6. Computer poisoning has destroyed the boot area and system, and the boot area can't be found when it is turned on: repair the boot area and reinstall the system (one-click restore is also acceptable). Another thing you need to do is to restore BLOS to factory value. BLOS can also be discharged;
