Hi @Kent36 

 

Welcome to the HP Forum.

 

Your PC is about six years old.

 

I can't say for sure this fixes the problem but you might try replacing the CR2032 MB battery. This battery usually needs replacing around five years or so.

 

You might want to do this BIOS update for your MB if you haven't done it.

 

Regards
