I wear a lot of hats LVL Eoin OSullivan Consultant Commented: Sounds like a hardware error.. They look identical although one RAM slot is slighty damaged on the corner. I replaced it because the system was taking a long time to power up and would not pick up its internal hard drive. Some of the motherboards compastors appeared to be swollen on the old logic board.

Try leaving the damaged RAM slot empty.. LVL 4. Definitely a hardware error.

The only question is, is it bad RAM, or a bad logic board? Reset the SMC. After major hardware changes this is always a good idea: Depending on which iMac G5, this may help: Any chance the logic board you got is in fact bad?

  • Ebay, or other questionable source? I can't imagine there are many good ones out there for sale, given the demand. Apple charges so much for new replacements, I would recommend a differnt machine instead. The Intel Imacs are so much better, it isn't even close When there is no ram in the system it will beep only once.

    Does this help? On the up side, Apple had a three year extended warranty on G5 iMacs. Perhaps yours is still covered. If no. Experts Exchange Solution brought to you by Your issues matter to us.

I turned it on again and this time got 2 beeps.

    I looked at more stuff online and then tried pressing the SMU reset button, with no change. It sounds like I should next try replacing those RAM strips, which is what I'm about to start working on next.

    This means going out and finding a store that sells them, etc. In the meantime I thought I would post this and see if I get any good insight. I am in a tight spot here because while I do have most of my important files backed up I have a project I've been working on about 14 hours a day for the past week, which is not done yet, and which I need to present on Friday. I tried starting it in target mode but apparently this is not possible when the computer is in this state.

    PowerMac G5 Won't Start? Why?

    Dec 31, 1: Bad banks may mean that the memory modules installed are bad or that the slots in which they are installed are no longer working. Dec 31, 2: Then I came home and read this. Luckily my wife doesn't like to dry her hair with a towel. I applied a hair drier to the banks for a few minutes, then put the RAM back in and it booted up. I immediately backed up my project online.

    But that looks like a really useful set of references for problems even beyond what mine turned out to be, so I'd recommend people make note of it.
