I just built my first computer, installed Ubuntu, and now whenever I open a program or folder, whether it's firefox or my files, etc. I get a bunch of vertical lines or everything is ineligible. If I try to change the wallpaper or take a screenshot it just freezes. I'm having a hard time searching for an answer because I don't really know how to explain so here's a picture.
