Please help.

I was browsing the Device Manager and brought up my hard
drive, an IBM. I was looking to see if there was a new
driver. But I saw a dialog form and a checkbox to
automate my login so I would not need to type in my
password when my machine boots up...or so I thought. I
checked it and entered my password. I use Administrator
as login user.
Sadly, very sadly...I can not get into my computer. There
is no automatic start-up...it asks for password and my old
password and the one I enetered into the dialog form--
checkbox doesnot work. No combination of upper and case
of my password work.
Please someone tell me there is a way to get back in to my
computer....

Thanks
Mike
