Recently I bought a 980ti off eBay for a friend's computer. When I put it in his system the board got power from both the PCIe slot and the two 8 pin connectors, but no display. To see if there was some issue with the display adaptors I plugged into the second slot of my computer. Same thing power, but no display. When I went into windows neither device manager nor GPUZ detected a second graphics card. I tried my extra 1650 to see if it was a slot problem, but everything worked perfectly with the 1650. It seems that there is something obviously wrong with the card. I'd like to try and do a DDU but since it doesn't recognize a second card I don't know how to do that. How can I tell if my GPU is beyond repair or is still fixable. Any help would be greatly appreciated.
