The reason why the computer can t turn on when the master enters the machine??

In fact, there are many reasons why it can't be turned on, such as no power and memory sticks, which need to be checked one by one, if there are no problems, you need to take it to the repair shop to check.

There is a high probability that the power supply will be broken. Although you say that the power supply is good.

Test the computer's DC output cable to make sure there are 12V and 5V outputs.

If you are sure that it is a motherboard problem, just replace it directly, no matter which one is broken, there is no need to repair it.

The luckiest case is when the BIOS information is flushed out by the current to see if you can reflash the BIOS

If you are struck by lightning, you still directly see what hardware is broken, just replace it.

Returning to the factory is the best. You're not going to tell me it's been three years since the motherboard, are you?
