I recently installed an Nvidia Geforce 7600 GS (512mb, PCI-E) to my computer, which also has an integrated video card.
However, when I start up the computer with the monitor hooked up to the Nvidia card, all I get is a black screen. I've told BIOS to run the PCI Express card, not the Integrated one, and when I go into windows and look at device manager, it shows than an "unspecified vga device" is plugged in. The card turns on, the fan spins, etc., so I know that it is on, but for whatever reason when I download the drivers from the Nvidia site and try to install it, it gives me a message saying that "no drivers could be found that are compatible with current hardware."
Anyone have any suggestions? If necessary I can copy my system specs and motherboard on here, but I've checked and there's no apparent reason why any of it should be incompatible.
