Thanks to everyone who replied... Unfortunately I sold my old 650, upgraded
to a 7100, so I don't have it to test the PS in anymore...Aside from logic
board damage, I've also read that a "click-click" & no boot can mean that
the PS is being overloaded with too heavy a demand from something.
I tried booting with the hard drive (a half-height 100 MB Conner) detached,
thinking maybe that's it, but still the click-click.
The book where I read this advice also suggested Nubus cards as the culprit
for excess power draw...but this cx had only a mere Toby Card in it, which
turned out to run just fine in my 8100...& it's not like there was an
8*24GC in it or some bad boy like that that's known to overdraw Apple's
recommended allotment.
