GPU HELP!!

[aux9o]

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.

Make sure that you have actually extended the desktop onto that GPU. That's the number one culprit. What is the OS?

Always looking to learn new things. I do not understand what that means so could you explain it to me?

That's an OS-specific question. Basically, you're telling the OS that you want the screen to also be extended to that "other monitor" that is plugged into the second card. [You don't actually NEED another monitor, you just need Windows to think one is there long enough to extend the desktop and 'turn on' that card.]
