I was playing COD4 when the computer locked and told me to force a restart.

When I try to restart it, it takes forever then the force restart message comes up and it freezes again.

There is computer language on the screen when this happens with the words " Debugger called:panic"

Can anyone help?

Thanks

Brent

    Does it look like this?  http://support.apple.com/kb/TS3742

    If you're able to boot, launch the Console application by entering the first few letters of its name into a Spotlight search, and select the most recent panic log under System Diagnostic Reports. Post the contents -- the text, please, not a screenshot. For privacy’s sake, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header and body of the report, if it’s present (it may not be.) Please don't post "shutdownStall" or "hang" reports.

     

    If you can't boot in the usual way, try a safe boot. The instructions provided by Apple are as follows:

     

    • Be sure your Mac is shut down.
    • Press the power button.
    • Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
    • Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).

     

    During startup, you’ll see a progress bar, and then the login screen, which appears even if you normally log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.

     

    Safe mode is slower than normal, and some things won’t work at all.

    Yes it does. Every time I try to boot it.

    Thanks but I've tried to safe boot it and it doesn't happen.

    It throws those numbers and letters up on the screen then the message to restart comes up again.

    Is there a particular error code I should be looking for on the screen?

    open console in your utilities folder and post what is under kernel.log.

    Have you trie a system re-install? disc repair, permission repair?

    If you're getting the panic in safe mode, you need to reinstall the OS. That's assuming you've backed up your data. If you don't have backups, you need to do that first, if it's still possible.

  • Brent212_uk Level 1 (0 points)

    Unfortunately it will not boot up to do this. The restart message keeps coming up first.

    I managed to boot it in Safe Mode in Bootcamp and it said there was a hardware problem then it wouldn't go any further.

    It will not boot up with any of the 3 options- EFI mode, windows or recovery.

    Is it beyond repair?!! :-(

    I recently installed lion, 3 weeks ago, it has never run smoothly since.

    How do I reinstall the OS? Thanks

  • Linc Davis Level 10 (192,529 points)

    Back up all data, then boot from your recovery partition (command-R at startup) and reinstall the Mac OS. You don't need to erase the boot volume, and you won't need your backup unless something goes wrong. If your Mac didn’t ship with Lion, you’ll need the Apple ID and password you used to upgrade, so make a note of those before you begin.

  • Brent212_uk Level 1 (0 points)

    Thanks for your input. But it's not booting with command-R. I get 3 boot options when I hold the alt button and none of them are allowing me to boot the OS disc that I found when I got the MBPro. Unless I'm going something wrong which is likely!

    My data is backed up with a time capsule so installing the OS again would be a good solution.

    Are there any other ways of getting it in?

  • Linc Davis Level 10 (192,529 points)

    When you installed Lion, a recovery partition should have been installed. The only way it wouldn't have been is if you had an unusual partition scheme on your internal drive, and then you would have gotten a warning.

     

    If you don't have a recovery partition, or if it's corrupt, then your best option would be to create a bootable Lion installer on a USB flash key, which you can do on a working Mac that's running Lion:

     

    OS X Lion: About Lion Recovery Disk Assistant

     

    If that's not possible, then you can make a "Genius" appointment at an Apple Store and ask them to install Lion for you, or make you an installer as above on a flash key you bring with you. I don't know whether they'll do either. Reinstalling 10.6 would be a last resort.

     

    If you can't boot from your installation DVD, then you have a hardware fault. From all you've said, I suspect that anyway.

    Thank you again for all your help. I've booked a Genius Bar appointment for this morning

    Turns out it was a faulty RAM module. Apple replaced it free of charge!
