emo problem

maybe you are a cartoon instead of a real person

someone stole all ur colours :o
rebellion! xD

hm i think it is a driver problem, many many people had this shit. Try search on google :x

reinstalling<? settings default<?

there is a cvar for that, but forgot it :x

download this http://www.nvidia.com/object/winxp_169.21_whql.html

or

Try using alt-tab keys or try via the taskbar to switch back from windows-to-game-to-windows-to-game multiple times.
After a couple of times it works, in sli mode too ! <- The graphics are restored ! No more black stuff

or

r_altModelLighting variable to 0

If drivers don't work, try flashing your hardware.

nice

you are such an emo :(

get new drivers np

Built-in-hax !

there was an ati driver ones with which you could change the colors of a game and invert the colors etc.

maybe that was your problem

Cutting helps!
