i tried to use the installation DVD to repair it,
Tried? What did the report state?
Please describe in detail all you have attempted to do in order to shut down your computer other than trying to use the installaton dvd? Did you try to shut down through the menu? Did you try the power button?
Have you disconnect all peripherals from your computer?

  • Can't shut down on iMac i7 unless I reboot another HD

    Using 10.6.7 and iMac i7...it refuses to shut down. Only way is to retart another HD and shut computer down from that. Have reinstalled system software several times, but problem remains. At one time I thought it might be due to VMware windows 7. Any help would be appreciated. Thanks

  • Finder can't shut down because copy and trash still running

    I was working in pictures, deleted and moved several . . . or tried to. After about 4 hours, the boxes for each show "Preparing to move to . . ." Set to stop an now below rolling bar it says "Stopping . . " How do I get rid of these functions so I can shut down my computer. Tried escaping, quit, manually shutting down - none work. HELP.

    Open Activity Monitor in the Utilities folder, set the Processes drop down menu to All Processes, locate the Finder, select it and click on the Quit icon in the toolbar, then click on the Force Quit button.

  • Can I shut down my PWP and replace it with a self-built website?

    I'm interested in creating a page at home.comcast.net/~tyler.schultz that redirects users to another website. Is it possible to shut down the PWP, move it, or create a page that the URL goes to instead of the PWP? Or does the PWP support a redirection code in Javascript? Thanks.

Thanks.Your redirect will work until they shut off PWP's and delete all the files. Hopefully you are notifying all who are redirected to your new page for the next few months to BOOKMARK the new address as the old one will soon go "poof" thanks to Comcast once again giving us LESS service for MORE money. May I ask what hosting service you went with and was it a free one or a pay service? Or did you just register a domain name and set up your own site?Thanks.

  • Can't shut down after going on line

    After going on line I am unable to shut down the computer without using the power button. If I start up and don't go on line I am able to shut down with no problem. I have even redone my internet connection. Have a dial up connection. I have done a clean install and after still having the problem I did another install. I have used Preferential Treatment and DiskWarrior but am still having the same problem. Have checked the permissions and trashed some preference files without any luck. When the computer is running I am not having any other problems, just can't shut down.

    You might try launching Activity Monitor from your Utilities folder, click on the Process ID to arrange things in the order in which they were launched. Take a look and see what has started running after Finder was launched. Activity monitor and pmTool will both be running, so too will Spotlight related processes mdimport and mds. Anything else, if you have quit all the programs you launched, is a potential candidate for interfering with shutdown, if it is refusing to let go. Those items with an icon are "regular" programs running, those without an icon are UNIX programs that are running. See if you have anything that might be related to Internet usuage that will not quit. You can force quit from the Activity Monitor.

  • Can't shut down computer. K9A2GM

    Hello!
    I have a strange problem, I can't shut down my computer. What happens is that I turn it off and windows shuts down and the screen says "turning off computer" or something. Then it's like that for like 15 minutes then everything goes black and the graphics card fan turns on at 100% speed. Then I have to press and hold the power button for 4 seconds to force it to shut down. I can't make it go into rest as well, the same thing happens.
    It all started when I bought a new graphics card ,Powercolor HD 4850, and installed it. I forgot to connect the power chord to the mainboard so when I started the computer the it started to beep and warned me that the power chord was disconnected. So I turned it off and connected it. When I started it again I got a message:
    "Warning!!! The previous overclocking had failed , and system will restore its default setting. Press any key to continue..."
    But since I had a USB keyboard that didn't work in BIOS I couldn't press any key. So I removed the battery to clear the BIOS and then it worked...but with this annoying problem instead.
    I have asked in several forums but they didn't know how to solve it. You're the experts I suppose...If you solve this one I'll be very grateful. My electrical bill is skyrocketing at the moment...

    Hi guys!
    I tried your suggestions but none of them worked so I finally reinstalled Windows. And it worked fine at the beginning, I could turn it off with no problem. I was later that night, when I was about to turn the computer off for the day, that the problems started. Windows update had downloaded some updates so it said "Installing updates do not turn off computer." It had 69 updates to install so I let the computer on over night. When I woke up the next day it was still on, back in windows. The problem was back...  What is different from my old problem is that the computer doesn't freeze this time.
    I reinstalled windows once more but the same thing happened.
    What happens is this:
    I turn it off, the screen says "turning off computer" but nothing happens. After like 5-10 minutes a blue screen occurs and it says somewhere on the top DRIVER_POWER_STATUS_FAILURE or something, can't remeber exactly. Then it restarts itself.
    This is starting to get annoying now...

  • The new firefox twitter app is great - except it disappears every time I shut down the computer and I have to remove and then reinstall it every day!?? I am working on an iMac - if that is causing the problem ...? Thanks.

    The new firefox twitter app (mini tab on left of page) is great - except it disappears every time I shut down the computer and I have to remove and then reinstall it every day!?? It won't appear on the page until I do. I am working on an iMac - if that is causing the problem ...? Thanks.

    Eustace, thank you so much for writing back.  I will try what you suggested!!
    thx for your reply - apparently when I went to the Apple store a long time ago, they restore maybe photos and itunes etc from my external hard drive (passport).  I guess at that time they reinstalled an earlier operating system than my macbook came with and that somehow corrupted FileVault.  apparently there was no sparse bundle (whatever that is) for my old admin account and they said that ever since the install of the older OS that it was actually NEVER backing up anything in my admin account.
    Then, I bought Time Capsule and starting backing up to that instead.  I started having problems with it being slow etc and then StartUp Disk full errors and didn't know what to do, so I "Restored" from Time Capsule and that's when I lost everything in my Admin account and was locked out when I tried to log in - it said File Vault error ..."
    anyway - that's THAT sad story.  I was told to create a new admin account and I've basically been trying to start over - even though I have a partial save of my computer in Crash Plan and I DO see a sparse bundle listed in there, but I just don't know enough about computers to know if it's something I can get back or if I am just totally doomed. 
    I'm afraid to reinstall anything because if there is even a remote shot that the other files are still floating around in my computer, I feel like that chance will be shot forever.  I need to hire McGee from NCIS, I just KNOW he could get those files back for me!!!

  • HT5361 I can't shut down my computer because it says mail is open.  It says to close mail and continue shut down.  Problem is I can't open or close mail now.  Can't shut down my computer at all.  What can I do?

    I can't shut down my computer because it says mail is open.  It says to close mail and continue shut down.  Problem is I can't open or close mail now.  Can't shut down my computer at all.  What can I do?

    If you cannot get mail to quit/force quit, you can always remove power from your Mac.
    NOTE: removing power is a bad idea, and can result in data loss, but sometimes it is the only thing left to do.
    Press and hold the power button for 5 to 10 seconds, and the Mac will power off.
    When you power back on, the Mac should reboot.

    I would instead say you have a problem since nearly all IPs work as advertised.  IF you do have a bad phone, take it into an Apple store and get a replacement.  Hope you didn't jailbreak your phone though as Apple probably will tell you, you broke it, you fix it.

  • Why can I not restart or shut down my imac without using the power button?

    why can I not restart or shut down my imac without using the power button?

    Reset the SMC and then try a restart or shutdown from the drop down menus.
    Intel-based Macs: Resetting the System Management Controller (SMC)
    Then if that doesn't work, backup because you have an OS X issue that will require either a repair or reinstall.
