Apple wanted about $1,700 to replace ONE. We said No, as the whole
computer's not even worth that much fully working... We were able to
find a single 2ghz CPU on eBay for about $100, but it didn't work,
even Apple couldn't get it to work after they ran the thermal
calibration, and they said that both CPU's were broken. Just to let
you know... Not to be a harbinger of doom :) You might be able to post
on LEM swap for new processors if re-thermal pasting them. On ours the
thermal paste was, indeed dried up, so that might have happened on
yours, and that could fix the problem, those G5's tend to run hot. Oh,
I just thought of this, (if possible) I would take it to the Apple
store for diagnostic, I think they'll run the thermal calibration at
no cost, which might fix your problem, and the diagnostic tool, also.
That should confirm if you have any bad hardware.
