So about half of the time I close World of Warcraft after playin it for a couple hours, the damn computer has been restarting. Not like a slow, Windows restart, it turns right off, and then starts up again. It only happens when i shut down Wow too, never when I'm playing it. I have a 6600gt and use the latest drivers and have reinstalled Wow, and it still does it. Any ideas of waht to do? If i should give more info on my system I will.
