Screen is black except a small strip at the top (Pictures)

I don't go on my Pc very often since its quite old and slow. I have a laptop so I only really need to go on my Pc when I wanna play one of my Steam games or something.

I set it up earlier with the intention of trying to speed it up a bit when I had a pop up telling me nvidia wanted updating so I clicked yes. The update failed and made my screen go weird (Screen was smaller and the little preview windows weren't coming up on the task bar) so I figured I'd turn it off and on again before trying a system restore.

Now it's on the password screen except I can only see this thin line at the top of the screen. The windows startup bit is fine and shows, but nothing after its working. I tried starting in safe mode and even managed to type my password in but nothing helped.





Any ideas on how to fix this?
