Had my new upgrade since November. Acer 4K G-sync monitor and a MSI GTX 980 to power it. Has worked like a charm till last night. Was playing Sunless sea and suddenly got 3 vertical stripes the full height of the screen. The center one moved with the center of the screen. So I quit, restarted the game, still there. Still there on the desktop as well. Fired up 3 other games, still there. Checked the temp and it was 30C. CPU was also 30C, so it wasn't that. Checked the fans and had a moment of panic when I saw the GPU fans weren't spinning. But I quickly discovered it was because the GPU was at 30C-duh. When I switched to manual I could spin the fans right up. I have not overclocked the card. I even installed new nvidia drivers. Rebooted the computer-still there. Shut down the computer and unplugged it. Brought it back up and it was still there. It was late at night so I just turned it all off and planned on testing different monitors and card today, but when I fired it back up this AM it was all gone. Any thoughts as to why it was going on? Sorry if I was to wordy.
