Lock Screen resetting repeatedly


New Member
Hey all!
I'm working on a computer atm. It boots just fine, but once it gets to the lock screen it will go to the sign-in, flash the theme color, then reset back to the lock screen. If i mash enter I can usually force it to sign in properly, but I suspect t the computer will be unusable if anyone adds a password. Ive run SFC and DISM, tried running startup repair, and at this point I suspect I just have to reinstall windows. Any ideas?
