So over the past week or so I've been having problems with my display. The screen would be split and the left half would be on the right side of the screen and vice versa, this usually happened when I was watching videos. I would reboot and it would be okay for a while, but now when I login to windows I get vertical blue lines everywhere or just a black screen, the login and boot screens are fine though, and I can boot into safe mode which is how I'm posting this.
I was thinking it might be the heat, but my GPU temp never went above 70C. and was usually at 55-60. My apartment is kind of hot, but the computer feels cool when I put my hand near it and the temps seem fine, usually never go over 65C and the fans don't even go above 33% speed on auto.
I don't have an extra video card to swap out to see if that's the issue and since I can boot into safe mode I'm hoping there is a more simple and cheaper fix. Would very much appreciate any help with this issue, thanks.
