I was having trouble getting my G3 up and running after changing the mother board battery. 2HD's one with OS9 other OSX.niether would show up on screen. Did a PRAM reset with some minor results, but the motherboard would never get past the disk ICON that shows up during boot up. Found the CUDA reset on the board and pressed and held it for 10 secs. Now I get nothing at all. Not even the chime. I tried CUDA several times to no avail. Is there anything I can do? Or is the thing toast? Ken

Will it boot from a CD?

If I understand you correctly, you were seeing the question mark startup icon. That simply means that the computer couldn't find/use the system software. (There definitely should be an FAQ on this.) You should have booted from a startup CD and investigated further. You likely needed to repair your hard drive(s) and/or reinstall the OS. Remember that software problems are far more likely than hardware ones. I don't know what to tell you about the newest problem you're having, though. Does your machine's power light go on when you attempt to boot? If it does but you hear no tone, it sounds like it's time for some new hardware.

Won't boot up at all. There is a SCSI 2 card in one of the PCI slots. and its lights come on as well as a fan or two, but that's it.
No chime, no power light, no nothing.
I've already looked into buying an eMac 8951LL/A. Looks like it's the one I'll go to next. Fortunatley most of my stuff is on back-up CD. About 6 mos. of stuff will be lost so it's not so bad. But bad enough. I was really hoping that there was something I could do to resurrect the poor old machine before it gets the final send off. I also hoped I could use it as a spare. Oh Well, I anybody has anything else to suggest, I open to options. Ken

I'm not sure how to fix the beige g3. I have the same machine, but if it wont even chime, and resetting the pmu/cuda isn't doing it, then I don't know.

How are you doing it? You're supposed to hit the button, wait 10 seconds, then power on.

Lastly, if you can't get the machine to boot, you don't have to say goodbye to the data on your hard drives. You can pull the drives out and put them in an external enclosure to convert them to firewire.

If they are IDE, that's easy, there are plenty of those kind of boxes. If they are SCSI drives, that might a bit trickier, but I think those converters do exist.
