Wow! A huge thanks to all of you so far! I didn't expect this many
replies. Here are some more details about it. I had checked it out to
see
if it was dirty, and it looked pretty clean (also no charred components
when
I glanced around inside). I can try cleaning it out again. All the fans
spool up for a few seconds before it just stops dead in its tracks. The
Apple P/N: 614-0157. It appears that there are no matches for this
machine
out there at the moment (DigAudio, MDD, Sawtooth are all different!).
Also,
the fans are all two wire as well, but if they are all working anyway I
wouldn't suspect that to be the issue. Another issue is that I have been
told it is remotely possible that the logic board is the problem instead.
That is much more expensive, and still difficult to tell which is causing
this strange problem.

I just had a machine come into the shop with the exact same
symptoms.

Try pressing the CUDA button for about 10 seconds with the power
unplugged, then see if it comes back up.
