    Mac shuts down
    Hello everyone,

    Recently my Mac is misbehaving
    Yesterday the screen went dark-grey and it says the system needs to be shutdown in about 3 to 5 different languages and of course shut itself down. This happened again a month ago.

    Can somebody please tell me what's wrong with my computer?
    Why is it doing that?
    The computer is a G5, Version: 10.4.11.

    Any suggestions please?

    Thank you guys!!

    Do you have an Intel Mac Pro or a PowerMac G5? Have you gone through disk utilities and done a permissions repair?

    You experienced a kernel panic.

    We need more details to be able to help you.

    - Is this an iMac G5 you have?
    - A PowerMac G5?

    Post the complete specs please.

    And did you change anything before this started happening? Like:

    1- Did you install new RAM?
    2- Did you add a peripheral?
    3- Did you change anything in your user account?
    4- Did you install new software? Or an update?
    5- What have you done on your own so far in terms of troubleshooting?

    I had this same problem with my ibook when i first got it, it costantly got the Kernel Panic. After many times of this happening i just tried booting off the installation disc, and going through the os x setup again. Haven't had a problem since.

    Try and give the info MacHaedCase is asking for.

    If it is hardware, then figure out what has changed.

    Also set up a new user account if you haven't already and see if the kernal panics happen in the new user.

    Refer yourself to this Apple Discussions thread, try to read the logs on your Mac and see what these are telling you: they contain what went wrong, the only trouble is trying to make sense of them!

    Here is some info on how to read them from MacFixIt and much more info at Apple's Developer Connection.

    Machead thank you for the links.

    I found out what causing my mac to shut down. It happens when I put it into sleep mode. Only then it shuts itself down.

    Can anybody please tell me why is that, if you know?
