It still may be power supply because every time the power turns off the PSU still makes that hissing sound.. i have the PSU separated from the mobo now so I know for sure that hissing sound is the PSU. Maybe it just does not have enough power to stay on? Although I'm unsure why it stays on continuously when I unplug the CPU power. Maybe because it is defective it does not have enough juice to continually power the CPU and mobo? This would explain why I had absolutely no power when I had everything connected like the hard drive and the DVD drive. The PSU couldn't handle it all. So maybe it is the PSU. I already ordered a new, different PSU from NewEgg (Corsair), they gave me free next day shipping so it is scheduled to be here Friday, but may probably get here on Monday because of the holidays. They are going to refund me on this OCZ.
But if it's not the PSU then what? I tell NewEgg that the mobo may be defected as well? If that doesn't fix it I call NewEgg again and say the CPU is defective?
