So let me tell you what happened recently, relocated to a new apartment and I transported all of my stuff with my car, my PC Case was placed standing up with all the components inside. After I arrived at the destination and cabled everything... shock! GPU could no longer be detected, had a mini heart attack as the GPU is just 4months OLD (GTX 1060 6GB), and besides, I used the computer literally 1 hour before I left and everything was in working order, it couldn't be the GPU right ? I moved the GPU in the second PCIE X16 slot and voila, everything works as it should ( the only problem being that the GPU is basically touching the sound card which is exactly underneath( and it kinda overheats) Replugged the GPU in the first PCIE X16 slot that ive always used and it still doesnt work, question is, what on earth happened ? I didn't drive on offroad terrain or anything, I just simply don't understand what happened to that slot.
