Re: Can't update nvidia drivers or do anything graphic wise
Try lowering the clocks on the card. I remember I had troubles very similar to this on my old GTX 285.
Lowering the clocks and adjusting fan speeds. Make sure the card isn't overheating, too.
EDIT: I should read more. So you're saying you can't get the drivers to install at all, even on a brand new installation of Windows 7?
What version are you installing? It might be worth trying the absolute latest beta drivers. If that doesn't work, try older versions of the driver.
