In your post title you refer to screen speakers but later in the post you say keyboard speakers? Can you clarify?
What could you have done:
1. You could have used one of the many boot discs available that allow to remove passwords to get into the system (Active@ Boot Disk would be my choice and it can be got from the same place you got your *cough*).
2. You could have caddied their hard drive & connected it to your PC and backed up all the drivers using a free program called Double Driver This neat little Prog lets you backup & restore drivers from the system you run it on but it also has a "Browse" button which allows you to backup drivers from any source. I love it too because it's portable so doesn't need to be installed.
