Cause of the problem?
Since the problem happens when booted in both OS 9 & OS X, it's
unlikely to be a software issue. You need to be thinking about
hardware problems. Zapping the PRAM isn't always enough, you may need
to reset the NVRAM by booting Cmd-Opt-O-F and typing:
set-defaults<Return>
reset-all<Return>
where <Return> means hit the Return key. Reply should be "ok" to the
1st command, and a restart to the 2nd command.
One thing that dramatically effects speed is the L2 cache. If the L2
cache isn't functional, the speed will be REALLY slow. The Sawtooth
has a 1MB L2 integrated into the G4 module. If the L2 goes bad, you
would normally see a warning when booting OS 9, and in OS X System
Profiler I believe a bad L2 is shown as "no L2" or "0MB"?
Bad RAM, or a bad HD, are other possibilities, but whatever it is,
since it's happening while booted in both OS 9 and OS X, it's highly
likely it's a hardware issue assuming that you've zapped the PRAM and
reset the NVRAM.
