UPDATE:
Best google search I've found was somone with the same issue that solved there problem but forgot to state what drivers they used.
» 8600 GT XXX Driver problem
I've tried nvidias newest witch is 186.18,then 185.85, then 175.19 and all achieve same result. A black screen after vista loading bar. I know the OS is active in the background because of my G11 keyboard and activity light on desktop tower.
Thanks again.
