well i have a problem with my computer. i noticed it just happens when im playing. when i start to play everything seems to be ok. but after a few minutes my screen turns black and i cant see the game anymore. happens for a few seconds then the game comes back for like 2 secs and it turns black again. it happened in css and l4d.
smurf said it could be the video card but hes not 100% sure about it. ill install some other games tomorrow and see if its also on those games.
maybe one of you guys can help me out and tell me if its rly the vid card.
thanks

Saj.
