Discussions on how to bypass passwords is not allowed on Tom's forums. Google what you need elsewhere.
BTW, if the system is yours, why would the password be different? There is no way we can verify you are the owner of the system in question. If you get the rig back, in one piece, and the system password (BIOS password) has been changed, then contact the vendor and be prepared to proof of ownership.
