Alternating light and dark blue screen on trying to start up

Today, on trying to restart after an Intego VirusBarrier update, I got stuck with just a blank blue screen alternating light and dark. I still can't restart on my internal drive, but after starting up from the install disc have managed to restart from a cloned OS 10.5.5 on my external drive. When I try to restart from the internal drive I just get the alternating shades of blue screen and nothing else - no error message, no question mark, just the pulsating blue screen - HELP!!!!

Thanks but that wasn't it. I replaced the battery and reset the PMU, still no luck. I've tried hooking up an external monitor still nothing, in doing all of this the person helping and I noticed that when you push the button on front to power up it doesn't light but I'm also not getting a start up chime, only the click of the hard drive then in pushing the button to power it off the light will blink and I think it is shutting down. Any other suggestions.
Thanks

    If a sad iPod icon or an exclamation point and folder icon appears on your iPod’s screen, or with sounds of clicking or HD whirring, it is usually the sign of a hard drive problem and you have the power to do something about it now. Your silver bullet of resolving your iPod issue – is to restore your iPod to factory settings.
    http://docs.info.apple.com/article.html?artnum=60983
    If you're having trouble, try these steps at different levels one at a time until the issue is resolved. These steps will often whip your iPod back into shape.
    Make sure you do all the following “TRYs”
    A. Try to wait 30 minutes while iPod is charging.
    B. Try another FireWire or USB through Dock Connector cable.
    C. Try another FireWire or USB port on your computer .
    D. Try to disconnect all devices from your computer's FireWire and USB ports.
    E. Try to download and install the latest version of iPod software and iTunes
    http://www.apple.com/itunes/download/
    For old and other versions of iPod updater for window you can get here
    http://www.ipodwizard.net/showthread.php?t=7369
    F. Try these five steps (known as the five Rs) and it would conquer most iPod issues.
    http://www.apple.com/support/ipod/five_rs/
    G. Try to put the iPod into Disk Mode if it fails to appear on the desktop
    http://docs.info.apple.com/article.html?artnum=93651
    If none of these steps address the issue, you may need to go to Intermediate level listed below in logical order. Check from the top of the lists to see if that is what keeping iPod from appearing on your computer in order for doing the Restore.
    Intermediate Level
    A. Try to connect your iPod with another computer with the iPod updater pre-installed.
    B. Still can’t see your iPod, put it in Disk Mode and connect with a computer, instead of doing a Restore on iPod Updater. Go and format the iPod instead.
    For Mac computer
    1. Open the disk utility, hope your iPod appears there (left hand side), highlight it
    2. Go to Tab “Partition”, click either “Delete” or “Partition”, if fails, skip this step and go to 3
    3. Go to Tab “Erase” , choose Volume Format as “MAC OS Extended (Journaled), and click Erase, again if fails, skip it and go to 4
    4. Same as step 3, but open the “Security Options....” and choose “Zero Out Data” before click Erase. It will take 1 to 2 hours to complete.
    5. Eject your iPod and do a Reset
    6. Open the iTunes 7 and click “Restore”
    For Window computer
    Go to folder “My Computer”
    Hope you can see your iPod there and right click on the iPod
    Choose “Format”. Ensure the settings are at “Default” and that “Quick Format” is not checked
    Now select “Format”
    Eject your iPod and do a Reset
    Open the iTunes 7 and click “Restore”
    In case you do not manage to do a “Format” on a window computer, try to use some 3rd party disk utility software, e.g.“HP USB Disk Storage Format Tool”.

    C. Windows users having trouble with their iPods should locate a Mac user. In many cases when an iPod won't show up on a PC that it will show up on the Mac. Then it can be restored. When the PC user returns to his computer the iPod will be recognized by the PC, reformatted for the PC, and usable again. By the way, it works in reverse too. A Mac user often can get his iPod back by connecting it to a PC and restoring it.
    Tips
    a. It does not matter whether the format is completed or not, the key is to erase (or partly) the corrupted firmware files on the Hard Drive of the iPod. After that, when the iPod re-connected with a computer, it will be recognized as an fresh external hard drive, it will show up on the iTunes 7.
    b. It is not a difficult issue for a Mac user to find a window base computer, for a PC user, if they can’t find any Mac user, they can go to a nearest Apple Shop for a favor.
    c. You may need to switch around the PC and Mac, try to do several attempts between “Format” and “Restore”

    A. Diagnostic mode solution
    If you have tried trouble shooting your iPod to no avail after all the steps above, chances are your iPod has a hardware problem. The iPod's built-in Diagnostic Mode is a quick and easy way to determine if you have a "bad" iPod.
    You need to restart your iPod before putting it into Diagnostic Mode. Check that your hold switch is off by sliding the switch away from the headphone jack. Toggle it on and off to be safe.
    Press and hold the following combination of buttons simultaneously for approximately 10 seconds to reset the iPod.
    iPod 1G to 3G: "Menu" and "Play/Pause"
    iPod 4G+ (includes Photo, Nano, Video, and Mini): "Menu" and "Select"
    The Apple logo will appear and you should feel the hard drive spinning up. Press and hold the following sequence of buttons:
    iPod 1G to 3G: "REW", "FFW" and "Select"
    iPod 4G+ (includes Photo, Nano, Video, and Mini): "Back" and "Select"
    You will hear an audible chirp sound (3G models and higher) and the Apple logo should appear backwards. You are now in Diagnostic Mode. Navigate the list of tests using "REW" and "FFW". The scroll wheel will not function while in diagnostic mode. For further details on Diagnostic mode can be found at http://www.methodshop.com/mp3/ipodsupport/diagnosticmode/
    Try to do the 5in1, HDD R/W and HDD scan tests. Some successful cases have been reported after the running the few tests under the Diagnostic mode. In case it does not work in your case, and the scan tests reports show some errors then it proves your iPod has a hardware problem and it needs a repairing service.
    B. Format your iPod with a start disk
    I have not tried this solution myself, I heard that there were few successful cases that the users managed to get their iPod (you must put your iPod in disk mode before connecting with a computer) mounted by the computer, which was booted by a system startup disk. For Mac, you can use the Disk Utility (on the Tiger OS system disk), for PC user, you can use the window OS system disk. Try to find a way to reformat your iPod, again it does not matter which format (FAT32, NTFS or HFS+) you choose, the key is to erase the corrupted system files on the iPod. Then eject your iPod and do a Reset to switch out from Disk Mode. Reboot your computer at the normal way, connect your iPod back with it, open the iPod updater, and hopefully your iPod will appear there for the Restore.
    If none of these steps address the issue, your iPod may need to be repaired.
    Consider setting up a mail-in repair for your iPod http://depot.info.apple.com/ipod/
    Or visit your local Apple Retail Store http://www.apple.com/retail/
    In case your iPod is no longer covered by the warranty and you want to find a second repairing company, you can try iPodResQ or ifixit at your own risk
    http://www.ipodresq.com/index.php
    http://www.ifixit.com/
    Just in case that you are at the following situation
    Your iPod warranty is expired
    You don’t want to pay any service charges
    You are prepared to buy a new one
    You can’t accept the re-sell value of your broken iPod
    Rather than leave your iPod as paper-weight or throw it away.
    You can try the following, but again, only do it as your last resort and at your own risk.
    Warning !!!! – It may or may not manage to solve your problem, and with a risk that you may further damage your iPod, which end up as an expensive paper weight or you need to pay more higher repairing cost. Therefore, please re-consider again whether you want to try the next level
    Last Resort Level
    1. . Disconnecting the Hard Drive and battery inside the iPod – Warning !! Your iPod warranty will be waived once you open the iPod.
    In Hong Kong there are some electronic shops offering an iPod service for Sad iPod, the first thing they do is to open up the iPod’s case and disconnecting the battery and the Hard Drive from the main board of the iPod. Wait for 5-10 minutes and reconnecting them back. The reason behind which I can think of is to do a fully reset of a processor of the iPod. In case you want do it itself and you believe that you are good on fixing the electronics devices and have experience to deal with small bits of electronic parts, then you can read the following of how to open the iPod case for battery and HDD replacement (with Quicktimes)

    http://discussions.apple.com/thread.jspa?messageID=2438774#2438774
    Have I tried these myself? No, I am afraid to do it myself as I am squeamish about tinkering inside electronic devices, I have few experiences that either I broke the parts (which are normally tiny or fragile) or failed to put the parts back to the main case. Therefore, I agree with suggestion to have it fixed by a Pro.

    I am not suggesting that you should follow as well, but just read them as your reference. You are the person to make the call.
    Finally, I read a fair comments from dwb, regarding of slapping the back of the iPod multiple times
    Quote “This has been discussed numerous times as a 'fix'. It does work, at least for a while. In fact I remember using the same basic trick to revive Seagate and Quantam drives back in the mid to late 1980's. Why these tiny hard drives go bad I don't know - could be the actuator gets stuck in place or misaligned. Could be the platter gets stuck or the motor gets stuck. 'Stiction' was a problem for drives back in the 80's. Unfortunately the fix can cause damage to the platter so we temporarily fix one problem by creating another. But I know of two instances where a little slap onto the table revived the iPods and they are still worked a year or more later.”UnQuote

  • Why does my ipad not work when powered up and screen just lights up dark blue?

    IPad Model A1219 does not respond when powered up, screen barely lights up just a dark blue screen thats it. will not do anything else, why?

    I think the subVI is working just fine when called from the main. I think what you're expecting is an indicator on the main VI to update as the subVI runs. What you will see on the main front panel is just the last value that a subVI has. That is the intended behavior of subVIs and function calls in all other languages. If you want to to update a front panel indicator while a subVI runs, pass a reference to the indicator into the subVI and update that reference instead of the indicator on the subVI. The other way is via a global variable. I've attached a modified version of your porgram.

  • After getting the dreaded gray/blue screen, I tried to run disk repair on the internal disk. I got an error message saying "Disk Utility can't repair this disk and restore your backed-up files. The volume Macintosh HD could not be verified completely

    After getting the dreaded gray/blue screen, I tried to run disk repair on the internal disk. I got an error message saying "Disk Utility can't repair this disk and restore your backed-up files. The volume Macintosh HD could not be verified completely." What do I do now? This is an iMac and I'm running 10.6.8.

    Clean Install of Snow Leopard
    Be sure to make a backup first because the following procedure will erase
    the drive and everything on it. See below for how to clone a drive.
         1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
             with your computer.  Insert the disc into the optical drive and restart the computer.
             After the chime press and hold down the  "C" key.  Release the key when you see
             a small spinning gear appear below the dark gray Apple logo.
         2. After the installer loads select your language and click on the Continue
             button. When the menu bar appears select Disk Utility from the Utilities menu.
             After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
             size.)  Click on the Partition tab in the DU main window.  Set the number of
             partitions to one (1) from the Partitions drop down menu, click on Options button
             and select GUID, click on OK, then set the format type to MacOS Extended
             (Journaled, if supported), then click on the Apply button.
         3. When the formatting has completed quit DU and return to the installer.  Proceed
             with the OS X installation and follow the directions included with the installer.
         4. When the installation has completed your computer will Restart into the Setup
             Assistant. Be sure you configure your initial admin account with the exact same
             username and password that you used on your old drive. After you finish Setup
             Assistant will complete the installation after which you will be running a fresh
             install of OS X.  You can now begin the update process by opening Software
             Update and installing all recommended updates to bring your installation current.
    Download and install Mac OS X 10.6.8 Update Combo v1.1.
    You may be able to backup your data if you have an erased external drive you can use. Before you do the above but after you have opened Disk Utility you can try to clone your drive:
    Clone using Restore Option of Disk Utility
      1. Open Disk Utility.
      2. Select the destination volume from the left side list.
      3. Click on the Restore tab in the DU main window.
      4. Select the destination volume from the left side list and drag
           it to the Destination entry field.
      5. Select the source volume from the left side list and drag it to
          the Source entry field.
      6. Double-check you got it right, then click on the Restore button.
    Destination means the external backup drive. Source means the internal startup drive.
    Now this will only work if the drive is accessible and can be cloned by Disk Utility. Otherwise, you would need to access your drive from another Mac that you can connect via Firewire - Target Disk Mode.

If it doesn't work take back to Apple Store. Cheers Brian

  • Light and dark solid grey vertical lines appear randomly on screen

    This has happened about 4 times in the last couple of months, when these light and dark solid grey lines appear on my screen, I have to turn my computer off by holding down the power button and rebooting it, it fixes the problem for the time being. These lines appear randomly, they have appeared when using Photoshop CS6, also when just using the internet, listening to Pandora. 1 out of the 4 times these lines appeared, there was a ticking/clicking noise... I took it to the local computer shop and they did tests on it twice and found nothing.
    Processor:
         2.66 GHz Intel Core 2 Duo
    Memory:
         4 GB 800 MHz DDR2 SDRAM
    Hard Drive:
      Capacity:    319.73 GB
      Available:    144.87 GB

    Run Apple Hardware Test in extended mode a minimum of 3x back to back. If errors appear this confirms a hardware issue that can only be fixed by taking the machine in for repair.

  • My i860 canon printer is suddenly printing color pictures with light blue and darker blue horizontal

    My i860 canon printer is suddenly printing color pictures with light blue and darker blue horizontal lines.  I have changed the cyan blue cartridge and the problem still exists.  Does anyone know what the problem is?  Thanks.

    Hi CSM,
    We can perform a print head cleaning and alignment on the printer to try and resolve the issue.  To do this, please follow the steps below:
    PRINT HEAD CLEANING
    With the printer powered on, press and hold the <Resume/Cancel> button. 
    <1> Resume/Cancel button
    When the power lamp blinks once, release the button.
    Note:  The power lamp will blink and print head cleaning will start. The cleaning completes when the power lamp stops blinking.  (It will take about 30 seconds to a minute for the power lamp to stop blinking and remain lit solid green.)
    PRINT HEAD ALIGNMENT
    Confirm that the printer is powered on, and load Letter-sized white plain paper in the sheet feeder.  
    Note:  If paper other than Letter-sized white plain paper is loaded, print head alignment cannot be performed properly.  The automatic print head alignment must be performed from the Automatic Sheet Feeder on the top of the printer.  It cannot be performed from the cassette.
    Press and hold the <Resume/Cancel> button, and release it when the Power lamp blinks four times.  (The Power lamp will start blinking and pattern printing will start.)  
    Print head alignment will start automatically as the following pattern is printed.  
    Note:  Please wait approx. three minutes until printing is completed.
    Hope this helps!

  • HT201263 I am getting a dark blue screen on my ipad 2. it would not turn on

    Since last Thursday, I noticed that when I went to turn on my ipad only a dark grey screen appeared. I then charged it over night and tried to turn it on the next morning. It turned on. Last night I tried to turn it on again and it only showed me a dark blue screen this time.  I put it on charge again overnight. this morning I ried to turn it on and still there is that blue screen. I went online to reseach what to do next. It was suggested that I restore the device.  I followed th instructions and did that. There is still a blue screen.  PLEASE HELP.

    Reset iPad
    Hold down the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears
    Note: Data will not be affected.

  • Stuck on dark blue screen on boot up Macbook Pro

    I was opening emails and my computer froze and a dark blue screen came up with no words. Then I tried rebutting in safe mode, while holding command r, and in recovery mode. Nothing will boot.  Every time the computer gets past the gray screen with the apple logo it goes back to the dark blue screen. I was able to use a lightning cable to get the data i need off the computer in target mode. Any ideas?

    How full is your HD? I had this same problem and the Genius Bar guy thought that the lack of space on the HD led to file corruption during virtual memory swapping. After deleting ~10 GB of files (backed up, of course), I re-installed the OS from the install disk and everything seems fine now.

  • Skype video crashes my GPU driver and causes blue screen.

    Hello,
    Installed a new copy of windows and got the latest version of skype for my PC (on wich skype worked just fine, video calls, voice calls, but it was an older version. No hardware changes)
    With the new skype, I , for the least, get driver crashes, and for the most, a blue screen, when I just go to options to set up my webcam.As soon as I see the square "loading" my webcam in the options, everything freezes and I get a driver crash or a blue screen.
    Current specs:
    i5 4440, stock clocks
    2x8gb 1333 ddr3 1.5v ram, stock
    R7 260x, stock
    500w PSU, not the best quality, But I also tried a 1000w platinum PSU, and same resaults.
    last error code I remeber from the blue screen was: 0x00000116
    I know it is related to the GPU, but it doesn't have power deficiency, since I manage to run heavy games just fine.By the way, my webcam works just fine on different web sites, so it's not the webcam.
    What I tried:
    -Degrading to the oldest supported version by skype
    -Degrading video drivers
    -Using different webcams
    -Installed all windows 7 64 bit updates
    edit:
    skype 6.14 works, but newer versions crash my GPU drivers and cause blue screen

    I would suggest uninstalling Droidcam as it could be the source of some delays assisting in causing the problem.  TDR problems occur when your videocard is unable to respond in 2 seconds for a variety of reasons (heat, tweaks), forcefully resetting the card.  Some people increase this delay in their registry from 2 to up to 10 seconds to give the card time to catch up so that a reset doesn't occur.  You can try this MS fix it which increases this delay. https://support.microsoft.com/en-us/kb/2665946

  • Phone is stuck on Dark blue screen

    How can I, if it is possible, get my iPhone 5C out of this dark blue screen that its stuck on. The phone is definitely on and I have it plugged into my computer but the screen isn't showing up- just a dark blue screen.

    Turn your phone off and connect your cable to the computer, but not the device just yet. Start up iTunes. Now, hold down the home button on your phone and plug it in to the cable - don't let go of the button until iTunes tells you it's detected a phone in recovery mode. Now you can restore to factory settings.

    When i take a photo or a video using the camera on my ipod touch, the computer (windows xp) shuts down and a blue screen comes up saying "an error has occured" and a heap of oth stuff in white. It doesn't wipe the memory or anything off the ipod. Whenever i sync my ipod without photos or videos it works fine. It also doesn't mind me taking photos off itunes to put on the ipod. I have had a look around and a couple of people say reinstall itunes, but i don't know if i will lose all my songs and apps. Any suggestions of help?

    Removing all Apple related software and reinstalling iTunes should bring all needed drivers back: Removing iTunes, QuickTime, and other software components for Windows XP
    Also check for new driver updates for Windows, especially if you have a webcam installed.
    iTunes Store purchases or songs imported from CDs are saved in your My Music folder by default and are not deleted by removing iTunes. While it is highly unlikely that you will lose any contents of your iTunes Library when following these steps, it is always a good idea to ensure that your iTunes library is backed up. If you're unsure how to backup, see iTunes: Back up your iTunes library by copying to an external hard drive.
