I just got a new GTX 465 I installed it into my number one gpu slot. I put my old GTX 280 in the number 2. Powered up installed new drivers for the GTX 465 but windows does not see the GTX 280. I checked all power connections they are hooked up but the fan on the card is not turning.

Anybody have any suggestions for me? I was going to crunch with both cards untill I sell the gtx 280 and replaced it with another gtx 465.
