Doby - Yes, it was the PSU. A new 650W Thermaltake Toughpower is already on its way. The dead Enermax is still under warranty, so I figure I'll try to get a replacement to have on hand as a better-quality spare than the Ultra.

lazareth1 - My computer was plugged into a surge protector, which is part of the UPS/battery backup. I've always been maniacal about surge suppression, since we have so many brownouts here on the Cape. It turns out that the problem originated with the wiring in my apartment - I've learned that some of the outlets aren't properly grounded. My building is 100+ years old in a small town that used to be run with the, "wink, nod & look the other way system," as the electrician phrased it. Thankfully, codes are better enforced now + my landlord is usually reliable - he promised to have the electrician back to make the repairs by the end of the week.

In the meantime, I'll probably just keep using my old laptop since the 400W PSU is definitely underpowered for my main PC. Besides, I'm now even more afraid to even leave it plugged in - even in the "safe" outlets, since I'd have to use extension cords.
