I have asrock H87M pro4 motherboard updated firmware to 1.70 and when adding my EVGA gtx 580 video I cannot see new card and of coarse and cannot boot to it. Device does not show up in device manager either. I have set primary Intel 4600 to disable and no help, also set video to look at PCI express 1 slot no help and set pci to gen 2 no help as the gtx 580 is PCI E express 2.0, but should work on Auto detect, set to multiple displays no help. Please let me know what else I need to do to see gtx 580 video.
Thank you tech support,
