Been having issues with my computer since April. Just got back from vacation and attempted to fix it. Reinstalled windows, had it working until the same exact issue it had before popped up. The screen has blue and green flickering lines in the background, what I think is artifacting. Once everything started going on I tried to change the resolution but the highest it will go to is 1280 x 1024 on a 1080p monitor. After a few minutes on desktop with the screen messed up it will go to a permanent black screen without the system turning off. Is something in the computer failing or what can I do to fix it?
