I've got some problems with my graphics card... First I'll tell you the system specs:
ASUS MOBO p5w dh deluxe intel core2duo 6700 XFX Geforce 8800 gtx Windows xp sp2 2 gb of buffalo ram Hiper R 580 W PSU
Is there anything more you need?
Now the problem is especially with half life 2: after a few seconds the screen acts really strange. I don't know exactly how to explain, so I linked 2 screenshots; the 111 is the normal, the 222 is the one after 2 seconds. I hope anybody can help me...
