I recently had to replace my mobo and now my Radeon X 800 PCI-e works fine while in Windows XP or surfing, or reading emails, etc. but as soon as I open up a game software (doesn't seem to matter which one) or my DVD player the screen goes garbled and even sometimes hangs the computer, I have to reboot to fix the issue. Yet I don't seem to have any problems streaming video over the internet. Anybody have any suggestions??
I've updated everydriver I can think of, I have run dxdiag and everything seems to be working fine.
