Also now getting the problem. Game plays for 5 mins or so then atrefacts before CTD.
Spec is:
AMD X2 4200+
2GB RAM
Geforce 7900GT 256MB
Oddly, I was getting a falling frame rate, then I cleaned all my fans thinking it could be an overheating problem, now the FPS is maintained but the game crashes.
This only happens in ArmA. Nvidia's stress test works fine.
Strange.
