Ive just got a nvidia geforce 8600 gt and i put it in and installed the latest drivers for it, then i try to go on something and it my screen went black with lots of coloured dots and the mouse cursor has a square white box around it, then my pc freezes, i cant system restore because it does that when i click on a date to system restore, so i uninstalled my nvidia drivers, worked all fine then when i dloaded direct x it started happening again, and i need direct x to play every single one of my games, is there a way to fix this problem?

thanks
