I recently installed a new ASROCK 939NF4G-SATA2 motherboard with an AMD 64 3200+ processor. I did a fresh install of Windows XP and installed Service Pack 2. I also updated all of the mobo drivers (Audio, LAN, USB, AGP). When I am working in Windows it runs very good with no hicups or any issues. I also ran a burn test and then immediately checked the temperature (112 F). The problem is when I play my game of World of Warcraft. It will play fine and then suddenly my monitor (21" IBM CRT) goes black and then in a few seconds turns back on again. This will happen once or twice and then when it comes back it is locked up and I have CTRL ALT DEL to get back to the Windows screen. I have used a Pentium 1.8 with the same video card (ATI 9800) and it worked perfect with no problems. Any ideas?

I'm guessing it's your psu, but if not it could be your motherboard.

Do you have the latest graphics drivers? Could it be possible that you ahve a cheap PSU? And are you running the graphis too high or overclocking your gfx card too high causing it to overheat.
