Michael, did you do a self-test on it?  (opt-apple down while turning on
the computer).  Do you have a zipgs or Transwarp in it?  If so, you'll get
an error, but if you can, take it out and put in the original cpu chip and
self-test it.  It DOES, however, sound like a flakey power supply, the
demise of which can do real bizarre things with a IIGS, including giving
you harddrive errors (like partitions being damaged, etc.)  Even a failing
battery can do wierd things...

With the symptoms you describe, I'd highly suspect a power supply
(especially the dead fan and LEDs).  If you have access to another IIGS,
maybe you could borrow the p/s and give it a try first.  If nothing else,
I have a good power supply, but a bad esoniq chip on a rom 01 IIGS.  my
