I recently got my hands on a gtx titan so I wanted to upgrade to that one from my gtx 1050ti.But whenever I put it on my motherboard it refuses to post on screen.I tried everything from the psu resitting the gpu checking the ram and resetting the cmos also updating to the latest bios version, but nothing worked. I tried the card on my brother's pc and it worked perfectly fine but when I tried his 5700xt on my pc it wouldn't post too. I believe that the pcie slot is faulty on my motherboard(note that the gtx 1050ti works perfectly fine and posts but the other cards don't even though they work on my brother's pc). If so what do you suggest on doing. Thank you very much for your help and time.
