Should this card work in a non-Dell PC? I installed it in my tower and the auto-detect on the nVidia site doesn't detect it. It came with a long frame extension, which I removed so it would fit in my home-grown PC. It doesn't show up in Device Manager, either.
Motherboard: Intel Desktop Board DG965WH

It happens often the nVidia site won't detect your vga card it is usually a Java issue you can manually go thru the menu and download your driver. It is strange your DM doesn't see it. Did you go into the bios and turn off the on-board video?
