Login Screen not appearing until multiple restarts

[ErinOsborne]

I went into my BIOS and changed it so the function key would work only when I pressed Fn. As soon as I exited BIOS my laptop starts up like normal but once you get to the start screen and click to go to the login screen it just goes to a blank screen with restart and shutdown options. If I restart it usually comes up eventually but I can have to restart it 3 or more times before I can login. 

The laptop is only about 2 months old and I don't have a installation disc or USB so haven't been able to follow other forums advice. Also when I exited the BIOS my Pin wasn't working and I haven't been allowed to set one up since then, I click on Add Pin and it just has a loading symbol and then stops.

Thanks for your reply! I haven't done what you asked because a few hours after I posted the question the Computer updated itself and everything seems to be completely fixed now! 

However if I do start to notice any issues within the next few days I'll follow your advice and see if it works. 

Thanks very much
