Hey guys... Today I've had a major issue with my 2900XT. Basically I turned on my PC on stock clocks ( see my system specs ) and I noticed some artifacts on my screen during the post screen. It was working fine until it got to the bit where you have to sign in on Vista. Basically there are tonnes of artifacts all over the screen and to be honest I would of thought this was a overheating issue but it's not. The reason I know it's not is because it works fine in Safemode not a single artifact. So then I uninstalled the drivers for my card rebooted, worked fine. But now of course I can't play any demanding games above minesweeper -.-. Every time I install the ATi drivers for my PC ( Yes they are the correct ones Vista 86x ) it works fine until it tells me I need to restart and once it loads into Vista and gets to the login screen, we're back to square one. If you guys need more info or what ever please post here I need help ASAP as this is affecting my schoolwork. Also I'll post a video of what happens.
