After three weaks or so without problems I have some stange issues with my 208X royalQueen card: After a cold boot (and only when the PC was switched off for more than a few hours) i’m getting artifacts durning boot (even in BIOS, so i can say this isn’t a driver issue)… vertical lines and white squares. The artifcacts are still present in windows, but most of the time windows goes straight to a BSOD or won’t show any picture at all. After a few hard resets the problems are gone, and then everthing is finde… good performance, even in high-demanding games or stuff like Furmark and 3DMark there are no artifacts at all.
In fact, in never encountered artifacts in a game (even on high) setting, the problem occures only at a cold boot and in low demanding enviroments.
What could be the cause of the problem? Is the card defect or could there other issues?
