I built my current setup back in January of this year, all new parts, and I've begun seeing this message after my computer restarts itself without warning. It typically occurs when playing Final Fantasy XIV, but sometimes it happens with something as simple as online browsing. I'm not sure if the problem is that my husband's kept it on the tile floor, and not cleaned the dust from it once, if the PSU is no longer stable, or if the motherboard is just over-sensitive as I've seen in some posts. I tested the wall outlet and power strip/surge protector with a multimeter, and everything read fine except for two outlets, which I've told him to avoid.
Here's the part list if it helps:
Intel Core i5-3470 3.2GHz Quad-Core
Corsair Vengeance 8GB DDR3-1600
Mushkin Chronos 60GB 2.5" SSD
Western Digital Caviar Black 1TB
PNY GeForce GTX 660 2GB
Corsair 600W Builder Series ATX12V
The Corsair Builder Series is actually supposed to be pretty reliable from what I read, so I'm fairly certain that's not the problem, but I can't be sure with how nasty he let the vents get. Inside the case wasn't too gross, but there is a light layer of dust over the components. Not enough to cause a problem, I would think, but I wouldn't be asking if I knew for certain.
I've read some things saying to just disable the anti-surge feature, but if he's borked the power supply, I don't want to risk ruining the motherboard.
