When I first got my June 2004 Dual G5, the first thing I did was restore from DVD (10.3). Mostly as an experiment.

Anyway, after that I would get random OS freezes. Usually I could ssh in and kill the process that was consuming the processor and get back, yet it was still very frustrating.

Long story short: It seems my install DVD's were bad, so I got replacements, but what really solved it was Tiger. My machine now never freezes, I have uptimes of more than 30 days, it is rock solid.

One other thing to check is firmware updates.

Also, check the RAM, pull some of it and see if it will wake properly.

Lastly, does he have any USB/Firewire stuff connected?
