So I have this problem where whenever I power on my computer it does not respond immedietly, also I tried unplugging the power cable and power on won't turn on also, But whenever I wait couple minutes it turns on. It also randomly shut down it happens randomly with load and no load. Also I encountered overvoltage warning, and back then it does not have this problem. What seems to be the solution to this problem.
