I starting to think it might not be shorting out. When it shut`s off the led light on the M/B stays on. which makes me think that it might be a connection or the PS.

yes, and I bought it already with the cpu on, and I screwed it in properly. I even tried it without the screws.

another for 12v. the fan is right above the processor. it ran for less then an hour.

I have one plug in I don`t think it has a place for another.

All the LED are ok and when I unplug every thing and plug it back it does the same thing.(and it is an ATX PS)

Ok so I just built this computer and everything was going good. Then It just stopped powering on. I press the power button and nothing happens. Sometimes it starts up but quickly shuts off before...
