Could I get a little help from those of you who know more about computers than I?

A few days I try to log onto the internet on my laptop and instead of the dialup logon screen and then the Hotmail webpage coming up, a saved webpage (HP.html) in the Windows folder on my C drive came up as my start webpage and didn’t automatically dialup my internet. I can’t for the life of me figure out how it became my start up screen, nor do I know how to get rid of it. I’ve tried going into Internet Options and changing my homepage to hotmail and I’ve tried deleting the HP file, but every time I restart my computer it comes back as my main setting.

Can anyone help me out???
