I've got a 20" iMac G5 2Ghz that is behaving oddly.

When you turn it on, it starts up, chime and all, finds the system
folder, and proceeds to the gray Apple screen where the start-up
animation spins for a few seconds like normal, then the screen turns
blue and the finder refuses to load.  The cursor usually comes up and
I can move it around with the mouse, until the start-up animation
shows up again and start spinning, and spinning, and spinning...

If I leave it on long enough, sometimes the fan will kick on in high
gear, but not always.

I tried booting from a DVD, and I get the same behavior.  Zapping the
PRAM had no effect at all.  I opened the case, blew out the dust
bunnies and checked for bad capacitors.  The capacitors all look
healthy.  I've had enough of these particular iMacs have caps go all
bulgy, so I was pretty sure I'd find the problem there, and was
surprised when I did not.  I did not notice any odor coming from the
power source, but I did not remove it to look for evidence of bad caps
in the power source.  I'm not getting the usual symptoms of a bad
power source (won't turn on , turns itself off intermittently, fans
blowing loudly ALL the time), I just can't finish the startup
sequence.

Any ideas?
