Hey, so recently I got a new gtx 1060 3gb about 2 weeks ago. I first installed it and it did not work. At the time it seemed like it was a loose contact and that pushing the graphics card in the pcie slot solved the problem. The card worked perfectly fine for a week until today. The computer suddenly shut down. Now when I try to start the computer, it is stuck on the loading screen as if it was a stiff image. It has been an hour and it is still stuck on that same screen. Also, there seems to be a thin rainbowish line going across the top of my screen. When I tried this with my old graphics card, that line was not visible. This is a acer prebuilt computer and I have no clue on whats going on. Please help!
