I've been using my PC as a workstation, Xeon processors with a Quadro2000 card. I tried installing a new GTX580 3GB that I've had a for a while without using. It doesn't seem to work. The fans run, but no image is generated. The AMI POST Code is 2A "Intialize devices primary". I tried the Quadro card in the same slot, and the PCI-E slot works. Extra power connectors were connected both to the GTX card and to the motherboard. Any suggestions for what I can do to establish what's wrong. I did not get past this initial phase, so have not installed the GTX580 drivers.
