| G3 B&W not booting |
Posted by: tattar8 on 2013-03-23 13:42:33
As far as I can tell, it's a stock G3, but its not booting. I get a chime on powerup, and that's it. No video, no HD activity, No CD-ROM activity if I stick in an OSX 10.2 disc. Haven't really played around with it yet, what might be the case?

Dust on motherboard, dead spiders in there, bad pram battery, might reseat memory and video card. Moisture gets in there pretty good. Power supply could be going also. They are pretty easy to get a hold of. I may even have one lying around if I look.

Motherboard is clean, and I get no activity with the video card and all but 1 stick of RAM removed. Pressing the power button once shuts off the computer. That leaves the PRAM battery.

After putting in a new battery dont forget to push the button on the motherboard to clear pram data.

The G3's had the jumper block for the processor. It was blue under a label, is it still there? label missing? it may be overclocked, also processor may have been messed with. That would go with reseating things. Sorry as I get ahead of myself. I check for this stuff when it is in front of me I forget everything I check sometimes.

Thanks for all the suggestions. I tried to give it one last go before ordering a new battery, and found that it booted if used a different stick of RAM from the one I had left in there. Turns out that was preventing it from booting. The Mac then happily booted into OS 8.5.1.

Yep that will happen. Sometimes people would grab ram out of a PC and sometimes it will work sometimes not. My cube wont take PC100 marked stuff for 512mb sticks. It just says no way. I have to put in PC133. Just strange, maybe its time for caps in it also.

I have the same problem, the PRAM battery is new, all the case and components are clean, every module of RAM was tested and I've reseted the PRAM/CUDA a hundred times, but the problem persists. Any ideias how to fix this? xx(
