Periodically the computer screen darkens and requests shutdown

Periodically the computer screen darkens and requests shutdown
this problem inturrupts almost everything and it started happening ever since i installed snow leopard
i want to format the computer and reinstall regular leopard because of this problem
Basically what happens is:
•The System freezes and the screen darkens a few shades.
•A message appears requesting that i hold the power button to shut off and restart.
•When i restart a message appears that says, "You shut your computer down because of a problem"
and it requests i report it
so i reported it its happened at least once a day everyday since i installed leopard on the 28th

This is, what they call a "Kernel Panic" - a unrecoverable error encountered by the Operating System during operation.
I assume, that you did a Upgrade Installation from Leopard or Tiger. There is probably some incompatible KernelExtension or Application remaining, which causes the problem.
Can you open Console.app in Applications > Utilities. Inside Console, you go to Diagnostic Information > System Diagnostic Reports. Here's a list of all recent Application / Kernel Crashes. You are interested in the following files: "kernel_<date and time of the Crash>". Click on a few of these. You will find some Information about the crash inside. If you're lucky, there's something like this inside: "BSD process name corresponding to current thread: <APPLICATION NAME>". This can help identify the faulty App.
Also you might want to try starting in Safe Mode. If the Problem does not appear there, it's most certainly some Issue with old Software.

  • A VIRUS? the computer screen darkens like a shade and freezes!

    A curtain of shade comes over my screen and then the computer prompts me to restart my computer. WHAT'S WRONG?!!
    it has happened twice.
    Also, when I am on the internet, my window closes for no reason.

    I don't know anything about computers. What does this mean? Thank you SOOO much for all your help so far.

  • Ipod Touch 1st generation: blank white screen - I tried holding both buttons and connecting it to the computer, restoring it, and still nothing. What else can I do?

    Ipod Touch 1st generation: blank white screen - I tried holding both buttons and connecting it to the computer, restoring it, and still nothing. What else can I do? I did not drop it in water.

    Try:
    - iOS: Not responding or does not turn on
    - Also try DFU mode after try recovery mode
    How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
    - If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
    - If still not successful that indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

  • My daughter disconnected her iPod nano from the lead before ejecting the device.  It no longer syncs and we have re-set the device, but it now only occasionally appears on the computer screen any suggestions please?

    My daughter disconnected her iPod nano from the lead before ejecting the device.  It no longer syncs and we have re-set the device, but it now only occasionally appears on the computer screen any suggestions please?

    Restoring the iPod will do nothing to his iPhone.
    When you restore it wipes the iPod clean no matter what computer you use.
    The only plus to doing it form your home computer is if you have a backup stored there, then you can restore from the backup once it's done wiping.
    If you are away form your home computer, go ahead and use the computer you have to restore it, then when you get home, you can restore form any backup you may find. You can use this to help you do that when you get there: http://support.apple.com/kb/ht1766

  • I have Keynote 6.2 and when my Mac Pro is hooked to a projector I cannot get the presenter notes to show on the computer screen and not on the projected screen. Any ideas?

    I have Keynote 6.2 and when my MacPro is hooked to a projector with a slide presentation I cannot see my presentation notes on the computer screen and not on the projected screen. Any ideas?

    Somethings obviously gone wrong with your installation of Keynote.
    Try this repair for Keynote 6.2,  ensure you complete all the tasks and in the order shown:
    1  delete all the iWork applications if you have them, not just Keynote, using Appcleaner from Mac Update, its a freeware application
    2  empty the trash:  Finder > Empty Trash
    3  Shut down your Mac, wait 30 seconds, then hold down the Shift key while pressing the power button
    When you see the grey Apple symbol and progress indicator (a spinning gear), release the Shift key.
    If you are prompted to log in, type your password, then hold down the Shift key again as you click Log in.
    4   Let the Mac fully boot up, it will take longer as the OS is repairing the drive
    5  when fully booted, go to Applications > Utilities > Disc Utility; click on the boot drive then First Aid tab and click  repair disc permissions
    6  when complete, restart the Mac normally, Apple menu > Restart
    7  install Keynote from the Mac App Store
    let us know if this helped

  • So, after my iPod touch died, i plugged it into the computer to try and charge it, and now it keeps changing between the charging screen, the apple logo, and a blank black screen, still hasn't charged, and its been plugged in for almost an hour now

    So, after my iPod touch died, i plugged it into the computer to try and charge it, and now it keeps changing between the charging screen, the apple logo, and a blank black screen, still hasn't charged, and its been plugged in for almost an hour now

    See the not-charging topic of:
    iPod touch: Hardware troubleshooting
    Have you tried another cable?
    Another charging source? Does iTunes see the iPod when you connect to your computer?
    Look at the dock connector on the iPod. Look for abnormalities like bent or corroded contacts, foreign material and cracked or broken plastic.

  • My macbook pro no longer connects to my TV with the mini dvi to hdmi adapter. A while ago the computer fell down and hit the cable. How can I tell if the computer is working ok. Doesn't show mirroring any more.

    My macbook pro no longer connects to my TV with the mini dvi to hdmi adapter. A while ago the computer fell down and hit the cable. How can I tell if the computer is working ok. Doesn't show mirroring any more. Was working while watching a movie but when I pulled it out from the computer and put it back in the system would no longer mirrorr the screen on the TV.

    The best option is an appointment at an Apple store genius bar.  The evaluation will be for FREE!
