Thanks for the reply's guys.
Youtube doesn't work the videos area is black without interface buttons.
And xvideos porn site videos are flash/shockwave I just see white, no video at all.
I tried the reset thingy, didn't work.
What exactly do you mean with turn off and on internet explorer? close and open? xD
Isn't there a way to re-install or repair IE8? 
 
Maybe this Hijackthis log helps?
