  • M-Audio Audiophile 2496 PCI card installed, now computer will not turn off

    I installed Audiophile 2496 card + "live lite 4" software and now my computer will not turn off. It goes through the motions, but than just reboots. I have to hold the start button to kill it. I also have a Firmtek SATA PCI card and a USB 2.0 PCI card. Is there some way to solve this short of pulling the card?

    Hi-
    Do you have the proper driver version installed?

    Sorry, your only alternative is to take it in for repair. While on your way stop at a office supply store and look into a UPS. if you don't want to go to the Apple Store you can use an AASP, you can locate one in your area by clicking AASP Locator.

  • After installing iTunes and iPod, my computer will not turn off

    I am running Windows XP, and have just installed my new iPod nano and iTunes. Now my computer will not turn off. When I select "Turn off computer" in the start menu, the computer goes through the usual process of shutting down -- then it restarts automatically every time! Once it has started up again, it sends an Error report to windows -- but they are not coming forward with a solution for this problem. It appears as a problem created by an "Unknown device driver". I now have to turn my computer off by the wall. Does anyone know how to fix this problem?

    Try running the Combo update first ... OS X Mountain Lion Update v10.8.4 (Combo), and once it is successfully downloaded, then try to download 10.8.5.
    Sometimes the combo will correct any minor glitches in the system and also ensure all necessary updates to that point are included.

  • Hello, My white McBook (2008 or 2009) recently stopped turning on.  When I hook up the Magsafe power adapter, the light shows green, but the computer will not turn on, or make a sound.  I've tried the re-boot option, but nothing works.  Please advise!

    Hello,
    My white McBook (2008 or 2009) recently stopped turning on.  When I hook up the Magsafe power adapter, the light shows green, but the computer will not turn on, or make a sound.  I've tried the re-boot option, but nothing works.  I first thought I needed a new battery because the lights at the back are all off, but shouldn't the computer turn on once the power adapter is hooked up and the light on the Magsafe adapter shows green?  I'm a computer doofus, so please be kind.  Please advise!  Thanks in advance.

  • HT4061 My phone will not turn on. I did a hard reset but all that my screen will show is a picture indicating I should connect the power cord to iTunes (iTunes icon).I don't know my serial # and I do not have acces to my laptop

    My phone will not turn on. I did a hard reset but all that my screen will show is a picture indicating I should connect the power cord to iTunes (power cord symbol with an arrow iTunes icon).I don't know my serial # and I do not have acces to my laptop.

    The serial number has nothing to do with this.
    YOur phone is in recovery mode.
    You will need access to a computer with itunes on it to restore your phone.

    I want to change my Apple ID to what I have as my rescue ID. The system will not let me.Is there a way to do this?

    You'll need to change/remove your rescue email address first :
       1.    Navigate to appleid.apple.com using your web browser.
        2.    Click "Manage your account"
        3.    When prompted, sign in using your Apple ID and password.
        4.    Click Password & Security
        5.    You'll be asked to answer 2 of your 3 security questions before you can make any modifications. If you are unable to remember your answers, you can choose to send an email to your rescue email to reset your security questions.
        6.    After you've validated your identity by correctly answering your security questions, click Edit to the right of your rescue email address.
        7.    Once you've finished editing your rescue email address, click the Save button directly below the email field.

  • CD-R will not eject.  Is there another way to eject besides the eject button?

    I inserted an old CD-R, which would not read and will not eject.  Is there another way to eject a disc?

    You could always try the old Terminal trick...
    drutil eject
    Don't know if it will work, but it may be worth a try.

  • I cleaned my wireless keyboard with a cloth that had a few sprays of windex on it, wiping back and forth and up and down on the keys. Now, various keys are not working. Is there a way to "reset" the keyboard to restore the keys?

    I cleaned my wireless keyboard with a cloth that had a few sprays of windex on it, wiping back and forth and up and down on the keys. Now, various keys are not working. Is there a way to "reset" the keyboard to restore the keys?

    Thanks for replying (thorvsphoenix)
    The windex was sprayed on the cloth, not the keyboard. And only one or two pumps on a hand towel. No liquid seeped between the keys the towel was barely damp. You are saying the ammonia gas created the problem?
    I think It was more an issue of multiple keys being depressed at the same time that screwed up the configuration. That is why I need to "reboot" the keyboard.

  • My computer will not turn on but the psu light is on.

    My Hp Slimline Will not Turn on. Last Night I Turned It Off And this morning i Turned it on and  about 5 minutes later the computer turned its self off. The Cpu Light is on. But the Power outlet is okay and i Tried Everything. HELP!

    First, what is the model or product number of your pc?
    Next, what exactly happens?
    Turn off your computer and your monitor.
    Disconnect the power cord from the pc and from the wall outlet.
    Disconnect any external devices other than the monitor, keyboard and mouse. Disconnect any printers, cameras, external hard drives, etc.
    Hold in the power button and count to 10. (yes, with no power)
    Plug in the power cord directly into a wall outlet and into the pc.
    Turn on the computer.
    Turn on the monitor.
    What happens?
    Do we have blue lights on the power buttons for the pc and monitor?
    Do any other lights come on?
    Do you hear any sounds?
    Does anything come on the monitor?
    Does the monitor display any message?
    On the back of the computer there should be a small light near the power cord - is it on?
    Also, how is the monitor connected to the pc? VGA cable with blue ends, DVI with white ends, HDMI?

  • While my iPod touch was connected to a speaker dock, I found it very hot. Not it will not turn on. I have tried the reset options and they do not work. Neither iTunes nor any of my computers recognizes it when I plug in the usb. Is there a way to fix?

    Now it will not turn on. I have tried all the reset instructions with no luck. Neither iTunes nor any of my computers will recognize it when I plug it in. Is there any chance to get it working or am I out of luck? Please help if you can since I cannot afford to purchase a new one at this time. Thanks.

    Your iPhone is in recoverty mode at the moment so to possibly get it back up and running you would need to do a restore as you have been trying. Follow the steps in the article below for the specific error messages you have been receiving. If after following all steps the issue remains book an appointment at a local Apple Retail Store to have the iPhone evaluated.

  • HT1430 My 4th Gen iPod touch will not turn, doesnt charge, and i can't reset in computer because it says it is protected by a passcode, but i cant enter pass code because the screen stays black and won't even light up... What do I do

    My 4th gen iPod Touch has had a blank screen for about 3-4 weeks now, it will not turn on, sync, or charge. iTunes recognizes its plugged up, but i cant reset it because it says its passcode protected, but i cant enter passcode due to screen not lighting up or working. How do i fix this?

    Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.
    iOS: Wrong passcode results in red disabled screen
    If recovery mode does not work try DFU mode.

  • 3 beeps after ram upgrade, computer will not turn on, please help!  I have tried everything.

    I have a late 2011 Macbook Pro 15 inches, i recently upgraded the RAM from Crucial 8gb (4gbx2) to Crucial 16gb (8gbx2).  I have done thies before, was er careful, and had antistatic clip, clean work surface, etc. When trying to turn the computer on again, i hear 3 slow beeps, repeated three different times, and the computer does not turn on.  I have been looking around for solutions.
      I have already swapped the memory modules, cleaned them, dusted the whole computer with air can, put the old ram in and still have the 3 beep problem.  It no longer works even with the old ram.  The computer was working perfectly fine before this.
      Am i missin a step?  I saw in a video on youtube that i have to reset the RAM with Alt+P+R+Power button, but nothing happens.
      Please help, i am self employed and my Mac Book Pro is the computer i work with!
      I have Lion operating system, everything updated very recently.  Stock 512 gb hard drive.

    Thanks for the quick reply Allan, i have reseated the ram 4 times, swapping top and bottom Ram modules, and pushing them in firmly and pressing down evenly with both hands. 
    I tried to put the old ram in as well in case the New RAM was bad, and that did not work anymore either.  I am from Mexico and live in Mexico City, and it is not easy to send the RAM back and get an exchange.  I will go to a MAC repair center on monday, but think i am missing some simple step somewhere. As i said this is my work computer and i really need it!
      I have reread what i wrote before, to clarify my computer was working fine with the old 8 gigs of ram, i just wanted it to be faster, and bought 16 gb since they are now much cheaper than a few years ago.
