ok but just this once
ok so turn your computer off, when the first black screen comes up hit a button.. I think it's F8.
Anyway that's going to bring up some options, choose to boot up in safe mode. Now wait, once you get on you should see a new account called admin. Chances are there is no password on it unless you put one there. So log into admin, go into control panel, and from there you can change you normal accounts password.
you're welcome
