Ok so let me explain this issue. A few months ago I replaced the motherboard for a unrelated issue and I got a ASUS H87m pro(I think). Here is issue, and it has happened before. When I unplug the power supply for one reason or another, and plug it back in, the computer won't turn on. It will take a few hours to be able to even do anything, until then the motherboard light turns on(as it does upon being plugged in) but nothing happens when the power button is pushed, not even spinning fans. Last time it happened, I had to wait over night, and it worked again. I'm assuming this is what is going to happen again. Ideas? I really wish not to wait a few hours to work.
