How do I fix my Dell Desktop with Windows XP I bought at a yard sale?

Okay so I bought it at a garage sale and its a Dell Desktop with windows xp and right when I turn it on it asks for a user name and password. It doesn't even go to the home screen. I tried to set it back to factory settings and it still didn't work. How do I completely restore it back to factory settings without asking for a user name or password?
