So, in an effort to make my system almost silent I bought a new case that could fit my brand new, and huge silent heat sink. I moved all my hardware into the new case, and now it suddenly doesn't work...

I've tried a bare bones boot with the motherboard outside of the case, so the mobo touching metal isn't a possible problem. I also touched the PWR SW pins together, to see if it was a button issue or whatever, and I had the exact same problem.

The fans will spin for about a second, and this seems to be a fairly common problem that can be fixed the ways I've already tried, so I don't really know what to do now.

Could it be a processor problem? That would be awful.

Thanks in advance for your response.
