1, let's check the computer's power switch first to see if it won't bounce and is damaged. If the contact is poor, you need to press it several times to turn it on.
2. Replace the power supply on the host with other normal power supply and test it. If it can be turned on normally, there is something wrong with the power supply.
3, open the host to see if the internal plug-ins, memory, etc. are plugged in.
4. If all the above checks are invalid, there is something wrong with the motherboard.
Press the power switch several times repeatedly before the computer can be turned on. The solution is as follows.
1. If there is something wrong with the power switch, switch to another switch.
2. If there is something wrong with the power supply, it needs to be repaired or replaced.
3. Accessories such as memory chips inside the host are loose, just plug them in.
4. There is something wrong with the motherboard, so you can only take out the maintenance point and ask professionals to repair it.
