OK, many deep breaths later... I realized my processor heatsink wasn't properly seated. Hard to believe, but these things are running so hot (not overclocked) that one improperly set heatsink pin was enough to allow the processor to overheat
Well, its all good now, the system runs like a champ, and I've got enough new parts to make myself a new system. My wife thinks its a conspiracy, but I swear I was just trying to fix the comp
, I also added new thermal compound to the processor and cleaned all the boards and fans. Good luck all!
