PC just randomly decides to stop working???

My PC was always working fine didn’t use it yesterday. Today I disconnected my USB headphones from it while shut off, then later turned it on to update Fortnite. While it was updating I got a blue screen and it said it was gonna restart. I thought it was maybe due to downloading Fortnite but even when I’m not running epic games store the PC blue screens after a minute or two of use.

I checked for CPU temps, checked for corrupted files, and now I’m trying to automatic repair it. Issue is when it makes me put in my password after selecting my account it’s not taking it? It says it’s the incorrect password when I know my pc log in password and my Microsoft account password. Not accepting either???? I read that if I use a windows media installer and some other things it’ll make it so the password isn’t necessary. Don’t know how to proceed??? Any help is appreciated
