Pink screen?!?

After playing CSS on my pc i get a pink screen when i watch a video clip or something like that. Not all the videos i have do this but some of them do, and to fix the problem i have to reboot the pc then watch the video clips.

Its like a pink tinge appears over the video clips and they play fine apart from that.

Anyone know how to fix this?

Spec:

amd 64 4400+ dual core
1024mb corsair 400mhz ram
600w psu
7600gt xfx g-card pcie

what are you using to play the videos with (WMP)

Im using quicktime and winamp.

have you tried reinstalling them or uninstalling and reinstalling them, also try redownloading them uninstall then reinstall them

i think if you disable hardware acceleration in quicktime, it should sort it, i’ve tried to locate haw to do this in quicktime but i can’t find it, it will probably be in tools or preferances
