My windows has been crashing recently. But only when I am watching video, it works for about 10 mins then video freezes, windows artefacts and crashes... I have installed new ram recently and I have been messing around with video filters to try and get hd dvd working in media player classic (without success). I don't think its the ram, as just done 5 hours of orthos blend and 2 hours of memtest (at stock). So I think I have screwed up some windows files for playing video...
I also recently installed the latest nvidia drivers, so it could be that... I haven't tested games much recently but cod4 worked for about 10 mins when I tested the new drivers...
re-install time for me after exams
