  • PowerMac G5 Boot Up Issues

    Yes, I realize this machine is past its prime; however, I still need to keep it going if at all possible.

    When I attempted to boot up a couple of days ago, the white light would illuminate and then flash three times - no chime, nothing. Upon doing some research, three flashes indicated a RAM issue so I replaced all the RAM. Still nothing.

    Someone on the Mac Users Group suggested replacing the PRAM battery and since the original one was past its suggested lifespan, I tried that. Booted up on the first try.

    However, this morning it was back to three flashes again. On the second attempt it actually booted.

    All in all, kinda weird. If the issue were actually resolved, shouldn't it reliably boot up every time?

    Anyone else have any experience with this or suggestions (other than buying a brand new box)?

    I have not experienced what you describe. Do you recall if the startup chime was audible during these failed startup attempts that ended in the three flashes?

      But like you, I have not had that particular problem either so I wouldn't be quite sure of what to suggest.

      Perhaps something going south on the logic board?? For his sake, I certainly hope not.

        No audible chime - just three flashes, then a brief pause and then three flashes again and again.

        It WILL boot up now but not on the first attempt when cold. Sometimes it requires up to around ten attempts just to get to the point where the chime is audible.

        Definitely has me puzzled.

          Check to see if it will boot from the System DVD that came with your system, by inserting the disk, and booting with C key depressed.

          If it does boot up, run the hardware test, there should be instructions on the system DVD.

            The Powermac G5 was notorious for having the logic board go bad on it, as it did on mine. Eventually I couldn't get the damn thing to boot anymore, and a Mac Mini was cheaper than a new logic board for the Powermac. Good luck!

              Were you having similar symptoms to those being experienced by CKT?

              Hell, I'm certainly no expert on it either but is it even remotely possible that it could be a failing hard drive?

                After numerous attempts yesterday, I finally managed to get the damned thing to boot and it remained running all night in sleep mode. Thought I'd try to leave it powered up as I have a couple of jobs coming up for which I need this machine to complete. Unfortunately, it experienced a kernel panic while I was simply trying to check my emails.

                I have found a few used Powermac G5 2Gb machines for under $400 so I am thinking my next step will be to go that route. Sounds like a working spare machine is far cheaper than a logic board replacement and it would also buy me some much-needed time. Hopefully I can simply put my original hard drive in the newly-acquired box, boot up and go from there.

                Any thoughts on this approach (other than buyer beware)?

                  A quick update:

                  I went ahead and purchased a used but well-working G5 2Gb dual-processor machine from DV Warehouse in Hollywood this morning for $264 plus sales tax. It even had 3Gb of memory already installed making it an even more appealing value. I drove up to their facility from Orange County so I could evaluate the G5 before committing to the purchase. Their machine had a 40Gb hard drive which paled in comparison to the already paltry 160Gb drive from my old machine; however, I brought my old hard drive with me and installed it into their machine and everything booted up flawlessly. I then disconnected their drive so the G5 would boot directly from my drive and lo and behold - it was a perfect clone of my old machine!!

                  Guess now I just need to figure out what I'm going to do with the retired G5. I've come to the conclusion that the issue is with the logic board and replacing that component would cost me even more than the price I just paid for the refurbished machine. Looks like it's time to do some recycling.

                    yup, sounds like logic board fail. Good move on the ebay replacement tactic. I've helped a few clients go that route when they don't want to purchase on outright new mac. Superb deals on old macs are always around.

                      While I have no doubt believing that CKT experienced a logic board fail, what I don't understand is how on earth can a logic board even fail?? Especially one that has been reliable for years??

                      It's not like it has moving parts such as a hard drive does.

                      Can anyone here enlighten me on why this type of thing even occurs??

                        As with all electronic devices (i.e.; synths) parts are subject to failure, especially over time, usage, climate changes, electrical fluctuations. These things happen. Could be a cap blows up, a resistor busts, solder point becomes unattached. Things happen.

                          I remember replacing the battery on my old G4 Tower. I had to hold down a little button on the logic board to clear the PRAM. I can't remember how long to hold it for but I believe you hold it whilst booting the machine, or there again, maybe you hit it when the machine was on?!? Instructions somewhere on the net..

                          I know you have the new machine though but it's worth a go all the same. You might find it fixes the problem then you'll have a spare..!
