The computer can't be turned on, but it can be turned on normally after being heated by a hair dryer. What is the reason?

1, change the filter capacitor, because it is not impossible to start the capacitor repeatedly. Repeated startup is to charge the broken capacitor. When the capacitor reaches the capacity, the computer can be started. It is recommended to send the power supply for repair or replacement.

The filter capacitors in the motherboard and power box should be replaced, because the fault capacitor has small capacity at low temperature and large capacity at high temperature.

2. The board of directors has poor contact. The quality of the motherboard is not up to standard.

3. The environment is humid, and it is easy to get wet if there is too much dust on the computer accessories. Everyone knows that dust absorbs water. As long as the weather is bad and the humidity in the air is high, the dust will absorb the moisture in the air. If there is too much dust, the computer will get damp and won't start. Just blow dry with a hair dryer.
