These are the last letters written.......
Last week i became a software update, a security update, so i updated, then i needed to restart......upon restart i got the grey screen with the apple logo and then a whole lot of writting about panic...it goes like this:-

panic(cpu0 caller oOX002EIEC4)-unable to find driver for this platform: "PowerMac12,1"

and more writting in black and then a whole lot of writting in white which ends like this:-

panic: We are hanging here.......

After minutes left like this i believe it is the fan motor, starts whirring loudly.

What t..F..?
It is like matrix relaoded to me..please help
I tried to start up in safe mode after reading several other posts, the computer starts, i get the apple logo, the little circle keeps running under the logo, no writting appears, then after a minute or so the motor starts whirring again..........

    Hi-

    That is a kernel panic.
    Kernel panics are caused by failed or incompatible hardware, an corrupt or incompatible system files/drivers.

    Was the software update completed, or was it interrupted?

    You may need to reinstall the system to get it back if the cause is software.

    Hardware, well, first run the Apple Hardware Test disc.

    Hi thanks for your prompt response.
    I believe the update was finished as i got the window prompt to restart my computer.

    Where do i find the Apple Hardware Test disc?

    And if it is a software problem and i need to reinstall the system:
    Does that mean:
    1. I loose all my documents, work, etc.?
    2. can i do this myself, even if i have limited experience?
    3. I tried to reboot from the installation disc 1 and nothing happened, it just whirred alot and spewed out the disc with no change.
    4. If the fan motor, i believe it is, runns loud alot, what does that mean?

    I am not experienced with this level of computer handling but i am very quick to pick things up and fast at recognising and have patience, is it possible for me to do this myself or should i really go to a apple service repair centre?

    Thanks again
    your a life saver!

    Just to add some more information about my computer an me.

    I have added no other hardware to my computer since i brought it.

    I always add the security updates and most updates recommended by Apple.

    I have not added new software to the computer for a long time. I have Adobe CS2, i have used Skype for a long time.

    On this day and even in the last 6 months i have not added anything new to my computer.

    please help

    Where do i find the Apple Hardware Test disc?

    It is on a disc within the original shipping software disc set.
    Insert the disc, and hold C while starting.
    And if it is a software problem and i need to reinstall the system:
    Does that mean:
    1. I loose all my documents, work, etc.?

    With an Archive and Instal/Preserve User Settings, No.
    This option may not be possible, and an Erase and Install would remove all old files.

    Do you have a backup external drive?
    If a Time Machine (Leopard) backup exists, you could roll back to before the last update, in case of a bad/incompatible item in the update.
    In the case of a Reinstall, the system may be restored using the TM backup.

    If just an external firewire drive, does it have a bootable system copy on it?
    Will the machine boot to the external )use Option key during start to bring up the Startup manager).

    If no backup, well, I won't rub your nose in it.......
    2. can i do this myself, even if i have limited experience?

    Yes.

    3. I tried to reboot from the installation disc 1 and nothing happened, it just whirred alot and spewed out the disc with no change.

    This is not good.
    It may be a hardware issue, which will require a trip to a Mac repair center.
    4. If the fan motor, i believe it is, runns loud alot, what does that mean?

    There is power, and the system defaults to full on fans in the case of system failure, to protect sensitive parts from heat damage.

    For now, follow the steps outlined in this article:
    http://support.apple.com/kb/TS2570

    Perform each step (do it again if that is the case) in order.

    If you cannot boot to the OS install disc, use fsck instead.
    http://support.apple.com/kb/TS1417

    1- Boot to Single User Mode holding Command and S keys while starting.
    2- At the command-line prompt type:

    /sbin/fsck -fy

    3- Press Return.
    fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issue is found:

    *The volume (nameofvolume) appears to be OK*

    If fsck found issues and has altered, repaired, or fixed anything, it will display this message:

    *FILE SYSTEM WAS MODIFIED*
    Important: If this message appears, repeat the fsck command you typed in step 2 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).

    When fsck reports that your volume is OK, type reboot at the prompt and then press Return.
    Your computer should start up normally and allow you to log in.
