Green Screen while watching YouTube or other movies

Hi ppl
Everything was cool, I could watch movies in Windows Media Player, on youtube and other sites until today.

I was cleaning my PC from some stuff that I didn't need anymore.
I dud uninstall on couple things and after that I wanted to look a clip on youtube and
the screen just turned green. I checked other site same thing happened.

I tried uninstalling flash player, java and it didn't work.

What should I do
Please help
Thanks

Re-installing sorry*
Forgot to mention that the sound keeps going while the screen is green.
I clicked uninstall on DivX player, winamp with his toolbars, curse client( that was for my
World of Warcraft game that I stopped playing)
