Hey guys. First time im using this forum. Alrite well my problem is that any PC game i play(Doom 3, Stronghold, Call of duty,etc.) basically crashes my computer within 15 minutes. Now i know its not a BSoD. When my computer crashes and i have sound on, the monitor(HP Compaq LA1905 Wide LCD) says it has "No source signal" and the sound freezes. Only thing i can do is shut down my computer. I can surf the web, watch videos, open any program just fine. Only PC games crash my computer. I got no idea why its starting to act like this. Heres DxDiag. If you need any more info please let me know.
