as a dual 2Ghz G5 I doubt we're talking an iMac...
but yes sounds like either faulty ram or logic board.
the G5 PowerMacs's ram is nice and easy to extract. take out all your
RAM chips and put one back in and see if it boots and stays stable
for an extended period of time, then take that one out and replace it
with another stick repeat until you've had each stick in there by its
self.
One of them _should_ cause the problem if it's faulty, if not it
could be the logic board.

It does sound rammy.
However, if you are game AND you have the iMac that is easy to open,
a few screws has the back off and a quick look will tell you if the
capacitors are bloated, they should look cylindrical with a flat
clean and shiny top surface.
So far I have not seen bloating in the caps that have a 'K' cut in
the top as opposed to an "X".

Not sure if Apple is still happily repairing these iMacs with bloated caps.
Good luck
