I have a dual 2.7 Ghz PPC G5 w/ 4.5 GB ram. The machine recently

Thanks for the help.

The Powersupply can be replaeced by remvoving the CPU not too hard
but be very careful of alignment removing it and replacing it. I can
send you instructions OFF-LIST if you need it.
Check the inside floor for any dampness it can be a leaking heat sink
and when a processor over heats the Dual 2.7's shut down. In my
experience a power supply works or doesn't work. You can unplug all
the connectors and clean. Also make sure system profiler is actually
reporting the 4.5 GB's of RAM. The RAM must be installed in pairs.
