    Default Imac G5- Blue Screen.

    Hi all,
    I posted this before, but in another thread.
    Sorry
    Imac G5 17'
    Purchased on ebay as Refurbished by Apple,
    Ram was maxed etc.
    No Paperwork, has worked great for 1 1/2 years.
    Now always boots to the dreaded blue screen.
    First tried a known good boot CD,
    Then a FW back-up.
    It chimes and attempts to start , the screen looks fine with the boot circle spinning.
    It will also boot into safe mode,
    and will boot to Applejack,
    Have also zapped PRAM,
    Unplugged it and let it sit for days...
    any ideas ????

    So...blue screen from DVD too?

    Any other bootable Macs around of a similar vintage that you could use to boot this machine to TDM?

    If it is a first gen G5 iMac (no camera) you can open it and press the SMC button pretty easily.

    Open it up and check for leaking/swelled capacitors. This was a common problem for the G5 iMac (and dozens of other similar era computers) even the replacement logic boards had the issue.

    If you do find leaking/swelled caps remove the hard drive and ram and sell the rest for scrap.

    If you don't find this issue, reseat all ram plugs etc and hit the reset button. Close it up and hope.
    Damien,

    Is there a Take apart PDF available for this iMac?
    A bit daunting but if it is considered scrap I suppose I don't have much to lose.
    Thanks to Uncle's post I have read about the capacitor issues.
    Relativity inexpensive to replace with higher quality caps.
    Thanks due.
    Thank you also Damien.
    A bit harsh but I'll accept your advice.

    Unfortunately another computer is not in my near future,
    and the little G4 laptop I am using and nursing along now is barely adequate and getting long in the tooth also.
    Phew...If I need a newer machine what is most reliable?
    Depressed,
    David

    If you have to move up, I whole heartedly recommend anything Intel based. Overall, they have been really solid.....expecting better life than the G5s as a group. Even a mid range used Mini, like a dual 1.83 or dual 2.0 would be a good replacement......unless you have to have lots of really fast storage. The internal 2.5 HD is the big limit there.

    For the first gen iMacs, start on page 42.

    Here's the process once you have the pizza box open.

    Long shot but worth a try.
