Asus P5K Pro
Intel Core 2 Duo 3ghz
nVidia 8800 GT 512mb
Windows Xp SP2

I can play with no problems every new game (from GTA4 to FarCry2 or Crysis).
Raven Shield works fine until the system crashes (black screen with looped sound, hard restart needed). It happens with RvS, Swat4 and America's Army... I suppose the problem it's with the 8800 GT.
Does anyone know a solution?
Thanks

Hmm, the only connection I see is that all the 3 games you have problems with are running on unreal engine 2.0.

I assume you have the lastest drivers installed. Maybe try some earlier versions of the latest driver?
