The strange nature of this problem is what is stumping me. I built my computer about 7 months ago using all new parts off of Newegg (not a kit or anything).

One day, I wake up and turn on my computer. I press the power button and it turns on, but then back off after half a second.

I press the power button again, this time nothing. I continue pressing the power button while at the same time turning the power supply on and off (to try and reset things). The power button still does nothing.

But then, after about 5 minutes, WALLAH, it works just fine like nothing was ever wrong.

It goes for an entire week working just fine. Then, one morning, the entire process starts again. I press the power button and it comes on and then right back off. I press the power button several times and nothing happens, and then it works again after a couple minutes of trying.

What is going on with my computer?
