...seems to be the same problem like Happy1´s:

 

Boot process stops when the display is not white anymore but getting blue for a short time (shortly before the user authentification screen appears). Then it goes back to a white screen without apple sign and doing nothing anymore. Starting from another internal HD with OS (10.6.8) is the same. Starting from DVD is not possible, the DVD-Recorder re-opens and gives the DVD back (which is working with another Mac).

 

Internal OS HDs seem to be ok because mouting as external devices via Firewire on another Mac is possible and the data on them is ok. Disc Utility says there are no problems on these HDs (once it said the number of folders is not correct, but it was able to repair this problem). But it also says something like "maybe refresh boot section" (whatever that means...: how if the DVD is not working anymore. The first time I had this it worked after using Disc Utility via another Mac).

 

Is it possible that there may be some problems with the battery? I had that problem on some of my earlier Macs, but I didn´t find something according the battery of the G5 Tower Dual. Somebody knows something about changing the battery? Or another helpful hint?

 

Thanks a lot

    Hi,

     

    What is the 2z691-****-A numbe on the Instal Disc?

     

    Might be time to replace the PRAM Battery, 4 years is close to their lifespan, far less if ever without AC power, & can cause strange startup problems...

     

    See which one your G5 has...

    Snow Leopard/10.6 won't run/work on a G5, nor will gray 10.4 or 10.5 Install Discs.

    You need to find a valid install DVD.  You need to focus on getting a valid DVD. I think you are going to have to do some type of re-install.  I do not know the status of how to get a restore dvd in Europe.

     

    Restore Tiger 10.4 & Leopard 10.5  DVDs are available from Apple by calling 800-767-2775 as of January 20, 2013. Have your serial number ready. Have your credit card ready too.  There is a small fee.

    Booting with alt-key shows the OS-HDs, but not the DVD. I tried an OS 10.6 DVD and an OS 10.5 DVD,

     

    If the DVD isn't bootable by your machine, it will not show up in startup manager.

     

    On the positive side, this is could be a messed up OS on the hd.  Since you are getting most of the way through booting, this greately reduces the probablity of a hardware problem.

     

    Try:

    -- Try a safe boot.

        Shutdown your machine.  Hold down the shift key.  Poweron.  Wait awhile Wait awhile while you harddrive

          is being checked.

    --  Run hardware diagnostics.  It's good for a sanity check.

     

    -- Try getting into single user mode. This page will tell you how to get into single user mode.

    Basically, you hold down the command + s key then  powering on your machine. The command key has a little apple symbol on the lower left. It is between the alt/option key and the space bar. On a PC keyboard, it will be the windows key, I think.

    You might be able to get your old software working on new hardware.  Here is what people are doing.

     

    new hardware like you laptop.

    parallels 8

    10.6 Snow Leopard server.

     

    10.6 includes software to run ppc programs.

    Do you know what is exactly the problem with 10.6 on that machine?

    10.6 only runs on Intel Macs, not any PPC Macs, (G3, G4, G5).

     

    Also, I doubt an Apple Store will even look at a PM G5.

     

    Leopard requirements/10.5.x...

     

        *  Mac computer with an Intel, PowerPC G5, or PowerPC G4 (867MHz or faster) processor

     

    minimum system requirements

     

        * 512MB of memory (I say 1.5GB for PPC at least, 2-3GB minimum for IntelMacs)

        * DVD drive for installation

        * 9GB of available disk space (I say 30GB at least)

    Classic/OS9 Apps no longer supported.

    Trouble is Apple no longer sells it, check eBay & such for the Retail version, not the Gray Discs...

    I'm confused about what machine you are writing about.  Please post specs on this machine.

     

    Query by serial number

    Apple's warrenty database will identify the type of Mac you have.  Your serial number is securely sent, but you get only the name of your machine.

    https://selfsolve.apple.com/agreementWarrantyDynamic.do

     

    This site provides more information, but lacks security.

    "A serial number is a unique, identifying number or group of numbers and letters assigned to an individual piece of hardware or software. It's used for various things depending on the product / brand but what is your Mac's serial number for and more importantly... what is it hiding and what can it do for you ?"

    CPU 4-7 disabled seems to be normal at startup.

    I suspect so, yours is 2 * Dual Core, for CPU0 to CPU3.
