Everything on my computer is zoomed bsod

Hello,

So I've been having this problem on and off for a while now and basically what happens is that everything on my computer gets really big (it used to also get really small something but that hasn't happened in awhile) and it's not because of the resolution or anything with how zoomed in my computer is, which seems to be the only solution that people have suggested on forums. Also for a while, when this would happen it would stay like that for a while, then I would try to play a game or something and then I would get the blue screen of death and it would say that there was a "critical structure corruption" or something like that, but that hasn't happened for a long time. One thing that I did that fixed this for a while was I turned off fast startup, and that worked for a while but the problem as re-surfaced and I have no idea what to do.
