I have been having problems with games crashing on my computer lately. I mainly play World of Warcraft. Whenever I start WoW my comp will run for 10 min or so and then I will get a VPU recover error. WoW will continue running for anywhere from 30 min to a few hours longer and at that point the monitor will flicker off but the computer will continue running. At this point I have to restart the comp to get the monitor to work again. I have the latest video card and chipset drivers along with completely upgaded win 2K OS. The only weird part is that this problem is intermittent, my comp may work fine for a week or so and then it starts crashing. I have reformatted numerous times and it seems to work ok immediately, but the problems always come back in a week or so. Forgot to mention I have a 420W raidmax power supply that came with the case. Any help to remedy this problem would be appreciated, thanks.
