Probably the board or the PSU it self is faulty. And I'm not talking about the amount of Watts aren't enough but that the PSU has an internal issue.

Next time explain your case better. Does it turn off when you open an app or game, or just while in windows doing nothing?

The pc is not turning on, and also the current is flowing outside the box. I think the psu is the reason.
