SetDeviceGammaRamp failed

[Hipshot]

This is odd. I think another application has donw something, so that I can't change the Gamma in Q3 any more. I can use ignoreHWgamma, but that's not the same thing. Problem occured several weeks ago and I don't remember what I was doing, it just appeared. I thought it was the nV driver, I later updated that one, problem not solved. A week ago my 7900GT died for some reason (might be heat), I got a cheap-ass backup card, 6200LE for like ~$30, still the same problem. Now, I got to borough this ATI X1950XTX or something like that, a very good card. The problem still exists, it's ludacris, I don't even have an nV card any more, so It can't be nV related, I had my system cleaned from the nV drivers... help?

check your dxdiag for any errors
