My G4 died );
The first time it had issues it just shut down on it's own and I though it was a power glitch at the house.
The second time I figured it was the computer and set up the backup to run but while running it died again.
It won't start at all. No blue screen, no nothing. Buddy says it's the power supply or the processor.

I backed it up to an external hard drive but Filevault won't let me access
the drive.
How do I get into the backup drive (get around Filevault) to salvage my data?
