I'd changed my PC's "Power Plan" from "Power Saving to High Performance because I'd noticed the framerate on my games had dropped a lot recently. I started up a game and everything was fine for a few minutes but then both my PC tower and monitor shut down. (They're both on a surge protector along with a printer) After I started my PC back up, I noticed my wallpaper from Wallpaper Engine had a single red line down the middle. I changed the wallpaper and noticed that the red line only affected "Video" wallpapers, not Scenes or Apps or any other. When I looked to YouTube for answers, every YT video had the same red line. I'd also noticed that my GFX card (AMD Dual-RX 480) was unusually hot on startup (~70 C instead of 40-50 C). I searched for some kind of crash report for a long time but I couldn't find one.
