Problem with computer randomly restarting! PSU?

I have the Intel monitoring software for my motherboard, and it's popping up warnings about my CPU core voltage being out of range, plus the +3.3, +5 and +12 being out of range, and my fans running unusually slow, 700rpm.

I just installed a new Antec 550 neo HE.

My system is:
Intel Prescott 551 3.4Ghz
1Gb DDr400
120 gb IDE HD
3 Fans(2 case, 1CPU)

Also, I had a power supply literally explode in my machine while maxed out on quake 4, and that was with a 450W generic supply. I replaced with the Antec, and I'm still getting random reboots, and these power discrepancy messages.

Is it possible that I simply damaged the motherboard? I've inspected each component, and everything looks fine. Heat is fine right now, so I don't believe that is an issue.

My question is what could be causing these errors? Is it the new PSU? Is it the Mobo? Help please!

  1. its not the powersupply.

    Im running an OC'ed Opty 146 w/ an X1900XT and a bunch fans on a NeoHE 500w/
  2. Any suggestions as to what may be the cause? Can heat cause voltage variations? What about the power strip my PC is plugged into? I know this is going to sound lame, but I also have a window unit air conditioner plugged into the same outlet, although it isn't plugged into the power strip where my computer is. Any thoughts?
