If you are not experienced in PCs, which I'm assuming you are not, you should not attempt to override a password of any kind. The reprecussions of a bad reset could severly damage your system. With that said, all passwords on a desktop can be reset by a jumper located on the system board. You should not change the state of any jumper on a system board if you are not completely confident on your actions. You could also contact Sony via phone or Website to obtain a manual for your system with detailed instructions.
