Well,
I bid on a Power Supply for a B&W G3 on eBay. I swapped out the Power Supply, and it's still not working. The processor is good, ram, everything else, so I've done everything, including taking the ram and processor out. I get not crashing sound. The computer just turns on, nothing more, no chime, nothing. I'm convinced now that the motherboard is bad. Must have been damaged in the move 6 months ago. I may go to eBay and purchase a new motherboard, but I'lll see.
Just a thought - fry pulling the PSU and PRAM battery off the board and leaving it to stand for a few hours (I do mine then go to bed and try them the next morning). A Mac left standing for 6 months is quite likely to have drained the PRAM battery almost completely, and as it died the PRAM becomes unstable under the wrong conditions. I've had no end (well, about 4 to date) instances of PowerMacs doing this at some point or other. Same symptoms, chime, not boot, black screen etc. Curiously despite all the flakey PRAM batteries I've encountered it's never happened on a 68k in my possession...
Anyhoo yank all power and pull the PRAM battery off the board and let it stew. Should do a fairly effective factory reset on the whole PRAM system.
