The first thing to try is a reset as discussed in http://support.hp.com/lv-en/document/c03546603

I was given a computer for my birthday, as mine is getting old. I've discovered that the computer was sold as being new, but is not, it has apparently been re-furbished. I am having all kinds of problems with the new one, and have decided to return it to the store. How do I eliminate all of my personal info before returning it? I'm not very tech savvy, so I need help with this. I saw something while exploring when I first received it that said it would restore the computer to the state it was in when purchased, but I can't find it now. The computer is an HP Laptop, (not a touch screen)computer with Windows 8.1. Thanks so much for the help!
