I used to work in an office with about 50 or so Macs and two of them had
this same problem and finally died of power supply failure, one with quite
a bit of smoke.  I have another two friends who have had theirs fail in
a similar way, again the problem was with the power supply.  A friend of 
mine who used to work at Apple indicated this symptom usually is an
indicator of impending powersupply failure.  I would be careful.  One of 
my friends said it took months to get his machine repaired after the
unit blew.
