So I lent my friend my GPU for a couple of months. It worked fine for me before and worked fine for him too. Now when I installed ti back to my pc it refuses to get recognized- code 31. I tried DDU with no success. GPU-Z displays a couple of details like brand name and device id, but is recognizing it too as microsoft basic display adapter. I dont know what to do now. Can provide any needed files and details. Thanks a lot!
