Just to keep you guys posted, it seems whatever happened only took out the PSU's. I have my i7 rig up on a spare PSU now. The q9550 is down for the count until I get a PSU for it, but have other things on the burner first. After I'm 100% sure the i7 rig is stable again it will be back and crunching 100% well I'm not gaming on it.
The electricians that came out didn't find anything wrong, they are just writing it up as a fluke. At least they didn't charge me.... and right now I'm just thankful whatever it was didn't make it's way to the home theater.....
