I'm not sure if his has already been asked, but there is some problem occurring with my login screen, instead of showing my account picture, account name, and the password bar there is just a blank screen. This problem has been occurring for a couple months now so unfortunately I can't recall anything that would have caused it. However, I do know that it hasn't been fixed by the most recent updates because of this. I've read that it has some thing to do with an error in the startup files. I believe it might be something to do with the computers inability to access my account's information to output onto the screen (the account picture and name) and be able to asses the user's credibility (password prompt), but I have no idea how to solve that issue. The problem was avoided by bypassing the login screen but I want the password prompt, it seems rather unsafe without it. How can I fix this?
