if it's got a G3 upgrade' date=' make sure the settings around right for the CPU.[/quote']G3s have nothing to do with this machine, except that the video card I tried happened to be from a G3 Power Mac.
I'm getting a bit frustrated by this machine. Nothing I do seems to fix it.
I just tried a known working ATX power supply, and it behaves the same way as before: chime, and then nothing. About the only thing the new P/S did was make the machine quieter!
Also, I examined the board near the memory slots, and found a row of small-ish chips where I'd imagine a fourth memory slot would've gone. That must mean that there is some built in memory, which explains why it still chimes when all the slots are empty.
I think I need a new logic board (or some component lever repairs dome on the current one). I highly doubt the CPU card is at fault.
Either that, or maybe I could just sell it and be rid of it? Opinions??
