Hello, and Welcome to DAL.
It's been a while since I've worked on a PB system. I've tried researching the PB website with your posted model number, but it doesn't let you get very far without a system serial number;

I can't remember if there's a hidden setup partition on the hard disk, similar to old Compaq systems. If so, you'll need the setup files to get things back to where they were.
See what information you can come up with at the above site and post back with your results and any further questions.
