The computer turns on fine, but after the login screen it goes black. I can still see and use the mouse icon, but there is no desktop. The screen is even blank when I try to go into safe mode! None of the fixes I find online are working, and a good portion of them go over my head. I'm not a computer wizard, I have no idea what I'm doing. If anyone knows how to fix it, if even temporarily, I would be grateful for any assistance.
