Whoops.
Seems that was a misdiagnosis. All my system
crashes are due to overheating.

Anything that pushes the ram, like moving graphics
or audio combined with mouse movements were
crashing the computer.

I've upgraded the processor, upgraded the graphics card,
and installed more RAM on my G4. All of this combined
causes the computer to overheat, which in turn causes
the RAM to malfunction and crash the computer.

My G4 (gigabit ethernet) has 2 fans in it, but I suppose
I'm gonna have to buy another one from Maplin.
Cleaning some of the dust off the first fan might have
helped too.

The endless troubleshooting was driving me up the
wall, I've reinstalled the system several times, deleted
corrupted preference files, changed the mouse, etc,
etc. I did feel it had something to do with RAM but
the ram cards themselves are ok as long as it doesn't
get too hot in there.
