So now i have purchased a new power supply, a corsair hx750, and I am still having the exact same problem! I am stumped. For the cpu, I set it in the holder, with the notches alligned, closed the holder, applied a pea sized drop of thermal grease, installed the heatsink. Any possible problems with that installation? I am just finding it hard to believe that I would get a bad power supply 2 times in a row, especially since i went with a considerably better power supply the second time...
