Windows 10: I can't login into my PC and don't understand why?

I was on my pc when it suddenly wasn't responding so I turned it off. once on again i tried to sign in but the sign in to put my pin isn't showing up. I've tried to do advanced settings and everything but once i get there and it asks for the password to my account and i type it in, it says it's incorrect. I've changed my microsoft password and typed in the new one and it still says incorrect password. I've tried opening in safe mode to no avail and everything won't work. I don't understand how i can go from playing games on my pc to not being able to even get in, in a matter of minutes. Help w

:)
