When I install my Graphic drivers my comp stops working??

Hi, I have this same d..n problem. It started on the 22 Feb after win7 SP1 was installed. Computer became very unstable - screen freezing, graphics intense programmes crashing. I have ended up clean reinstalling windows 3 times to track the problem. I now have SP1 and all important windows updates installed but when I try installing the drivers for the GST450 the screens go black after windows staring up screen and before the login screen. It appears the none of the available drivers for the GTS450 work with SP1. I have tried most of the versions from 260.89 to 266.58. I have uninstalled the drivers and am now running the card on the default VGA settings.

Either microsoft broke something in SP1 or nVidia need to update their drivers to fix this.

Any advice would be helpful.

Cheers
Chris

Have you visited any of the Nvidia forums to see if they have reported problems of this, and what solutions they offer? Might help.

I've sent my card to the company and they are sending me a new one back. hopefully should fix it..
