I recently installed a MSI K8T8000 board with a Athlon 64 3500+ proccessor and 1gig of 3200 RAM. Here is my problem. Everytime I run a graphic program like 3dmark5 or UT2004 the screen goes black and the computer locks up. I have a 480W power supply and I am only running one hard drive. I have flashed the video card, upgraded the bios and tried everything I know. I replaced the video card and tried that and I didn't have a problem, but I was wondering if anyon had any idea why my 9700 Pro will not work.
