that you agreed to when you joined, we cannot help you with this. While I understand your problem and frustration with this, it is simply impossible for us in an online capacity to determine that you are indeed the owner of the machine. Sadly, too many people pretend to have similar problems, when in fact they are trying to break into someone else's computer. Therefore, we respectfully decline to help anyone to recover a password, so that we don't accidentally help someone commit a crime.
I suggest you contact your computer's manufacturer, or take the machine to a local computer repair person for help.
Thank you for your cooperation and understanding.
