ou lost me here--this is a bit beyond my basic, limited abilities!
"if you can connect the old Mac to the new via Firewire and start the old in Target Disk Mode (start up while pressing T), you can use Disk Utility on the new Mac to erase the old."Should I be considering a sledge hammer?? I can be handy that way!

One of the coolest things about a Mac is that you can, at the press of a button, turn it into nothing more than an external hard drive.
You turn on the computer and hold down the T key on the keyboard. Instead of booting, you will just see the FireWire logo blinking on the screen. Now your computer is not acting like a computer; it's a FireWire drive. Connect one end of a FireWire cable to it, connect the other end to a different computer, and the Mac's hard drive will appear on the other computer. You can reformat it, erase it, copy files off it, or do whatever else you like.
It is very cool...but you do need a functioning logic board to make it happen. I doubt that Sooz has that, given the symptoms she's described.
