What should I do on this? This card worked fine for years in my machine and it was packed good in original packing. He told me it had the correct lights on it for working but he isn't getting any display from it. He tried to sli it with another card and then by itself. Now he is upset it doesn't work. Now it's not my fault he screwed up my card which is highly possible. But him saying he has a blue and yellow light on tells me it's working. Not sure what else to tell him as I said sold as is and no refunds. I am afraid he might slam my perfect 11 year eBay profile of 100% with bad feedback and hit paypal with a refund.
