I am having the same problem with a NV9200 PCI DVR card for CCTV and a DH67BL. This card works in an older system. I updated the bios to 156 but the problem still remains. I also set the onboard graphics to primary but the problem persists. Due to the cost of this PCI card I cannot just scrap it. PLEASE HELP!
PS: I also tried a sound card in the PCI slot and that works - So the PCI slot is working.
