please help if anyone know whats wrong

I've never known Defrag to scramble any files. But your first step should be to reinstall your graphics drivers, I'd say.

if you've already tried this, perhaps you could describe in greater detail what "purple pixel" meands. One pixel only?

a purple pixel? does it always show in the same place? how about POST does it appear there?

sorry guys, one of the problem is that i dont know how to discribe it... its like my pc is unable to render the graphics install come up with a whole screen of purple squares... I have tried reinstalling drivers, games and use all kind of thing to try to fixes it but nothing worked it has happen to all the game apart from overload... NFSC, Bioshock, Lost planet and i not sure what else but those are the ones that i know have been affected
