I would suggest you read over the http://www.computerforum.com/52038-forum-rules.html before asking these kinds of questions.I just found a backdoor password, I am now on the windows password screen. Now I just have to find a way to get into here so I can turn off the bios password and the windows password because I don't need either one of them.
Unfortunately we can not help you here.
The forum rules will not allow us to give help in this area.
The main reason is because we have absolutely no way to know that this is your computer.
If it was you should know the passwords.

That aside, google it. There are ways arounds passwords, but we can not help you with it.
