Hi guys, this morning I was just viewing thumbnails of some videos on my XPS when suddenly the screen went bonkers! white background with vertical lines moving around the screen. I did a reboot and everything was fine, Tried to view the videos again via thumbnail view and it happened again! I play games on it and it never gave ma a problem. Any ideas whats wrong with it? Should i do a clean installation of nvidia drivers? I think when i installed dell drivers, i never used drive cleaner, I just installed it and that was it but it never gave me problems before. 






I really don't know what to do now.
It seems to happen only in a specific folder when im viewing videos in thumbnails. I tried to view video thumbnails in my external hard drive and it was all fine. Is there like a nvidia gpu hardware diagnostics software that I can use to check if it is a hardware fault? Did a 3dmark 03 and it scored 20000+ is that normal? Cheers.
