idk what dgc is so you can keep the bounty if I help you resolve your issue
Right now, you have 3 probably points of failure. The PCI-e slot, the Riser cable, or the card itself. You need to swap with known good components, ie Try a riser cable you know works. If nothing, Try a PCI-e slot, you know works. If still nothing, you got a DOA card.,and you should contact the vendor, for an RMA number
Thanks mate. Bad PCI-E 1x to 16x.
