Vertical bars on screen and won't boot up

All of the sudden my MacBook won't boot up.  It has pink and gray verticals bars for a few minutes and then just goes gray and won't boot up. Can anyone help. 

Hey KatInTheHat2,
Thanks for using Apple Support Communities.
Sounds like it might be a screen issue or a computer issue. This first article discusses what to do if your Mac won't turn on.

    Hey Julius62,
    Thanks for the question. After reviewing your post, it sounds like you have a gray screen during startup. I would recommend that you read this article, it may be able to help you resolve or isolate the issue.

  • My iMac has the No sign at the grey screen and won't boot up.

    It's been acting strange lately-- I tried to run DiskWarrior 3 yesterday and it wouldn't boot up from the CD-- I did the hold down the C key as well as going in and clicking off the 'ignore' box.  I thought that it was because I needed a newer version of DiskWarrior-- but now I'm thinking maybe it was something bigger?
    Is there a safe way to make it boot up?  BTW-- I can't remember exactly which OS it has-- I'm 99% sure it's Snow Leopard, if that helps?
    Thanks!!

    Reinstall Snow Leopard:
    Reinstall OS X without erasing the drive
    Do the following:
    1. Repair the Hard Drive and Permissions
    Boot from your Snow Leopard Installer disc. 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 your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    2. Reinstall Snow Leopard
    If the drive is OK then quit DU and return to the installer.  Proceed with reinstalling OS X.  Note that the Snow Leopard installer will not erase your drive or disturb your files.  After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.

  • My late 2006 Black MacBook has a gray screen and won't boot.

    My late 2006 Black MacBook has a gray screen, folder icon, and flashing question mark.  I replaced the HD with a Western Digital 500 GB and had no change.  What's wrong with my MacBook?

    That folder with the question mark icon means that the MacBook can't find the boot directory. That can either mean it can't find the hard drive or the hard drive Operating System data is somehow corrupted.
    Put your install DVD into the optical drive and reboot. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option key until the Install Disk shows up). That will force your MacBook to boot from the install DVD in the optical drive.
    Once it has finished booting and you Choose Your Language and you are at the Install screen launch Disk Utility from the Utilities menu. Is your Hard Drive in the list on the left?
    If it is then select the First Aid Tab run Repair Disk and if that repairs any problems run it again until the green OK appears and then run Repair Permissions.
    If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead.

  • IPod stuck on black reboot screen and won't boot up

    I realize I made a mistake now. I went to Disk Utility and formatted my iPod for UNIX file system. I wanted to be able to plug it into a Linux machine and copy some files over.
    Now the iPod is stuck on the black reboot screen with the dim Apple logo. I can hear the hard drive in it attempting to boot up every few seconds.
    I can't get iTunes to see the iPod when I plug it in the dock. I can't even get my Mac to see the iPod now.
    Any suggestions on how I can Restore it? Or did I kill my poor iPod?

    I think I found the solution:
    http://docs.info.apple.com/article.html?artnum=61584
    Your suggestion is correct but I have to have it in Disk Mode first before I can format it back to HFS+ and then Restore.
    Thanks for the help!

  • Gray Screen and Won't Boot Up

    I posted this problem several weeks ago. Then there was an update. Everything went away until yesterday. Now I when I turn on the IMac 20" I get either a gray screen followed by the loud fan after a few minutes, or, I get folder with a question mark icon flashing on a gray screen. I have rebooted over and over and nothing changes. ANy one have any recommendations how to fix this - this time. Previously, this problem seem to coincide with an Apple update.

    The only thing I can think of short of a hardware or software problem is go into:
    System Preferences > Startup Disk, from here make sure you have the correct location selected, "on Macintosh HD"
    Also, which version of the iMac G5 do you own? Rev A, B, etc. You can go here: http://www.apple.com/support/exchange_repair/ check to see if your machine falls into any of the repair programs...

  • Mac Pro gets stuck on the grey screen and won't finish booting

    I have a Mac Pro 1, 1 recently (successfully) upgraded to snow leopard that gets stuck on the grey screen with the spinning rainbow cursor (after the apple logo and brief blue screen) and won't finish booting up. This happened after my computer froze up and I had to force quit.  I checked out the forums and I tried all the all the suggestions (like disconnecting peripherals) and appropriate disk utilities, saw no errors with the HD reported, and had no trouble doing a safe boot  (everything works o.k. there) or starting up from the software disk to perform the repairs.  I did notice that during the repair permissions command, it gets stuck in the last few minutes, the CD starts to chug along, and everything freezes and I have to force quit.  This happens every time I try it.  I eventually backed everything up, erased the HD and reinstalled the OS, reset PRAM and NVRAM, but I'm still getting the grey screen on restart.  Tech tool deluxe reports a "fail" on the video RAM, but everything else seems to check out.  Could it be a graphics card issue?   I did notice some funky visual glitches occurring prior to the breakdown.  Any other ideas?

    I wouldn't trust Apple Disk Utility to do a hard drive repair, but I would go with TechTool Pro 5/6 if you have that instead of Disk Warrior from Alsoft.
    Clone the drive, though you should have some bootable backup clones already; repair the clone; then boot and work from that drive. Always have a working copy of the system.
    And off load all your data to other drives.

  • My MacBook Pro has 10.5.8 but came with 10.5.7 install disc and won't boot up and can't reinstall

    My MacBook Pro has 10.5.8 but came with 10.5.7 install disc and won't boot up and can't reinstall.
    the disc is spinning and I see the apple on the screen with the spinning gear and after a while it just turns off OR the few times it does get past that point when I go into disc utility it tells me that it can not install on this machine!
    It's driving me crazy, please help!!!

    Welcome to the Apple community.
    I'm not entirely sure I follow you here, home sharing comes with iTunes 10.2, so far as I am aware even iTunes 10.6.1 only requires OS X 10.5.8 or better. On that basis I'm not sure why you think you have a problem.

  • IPod has a blank screen and won't do anything?

    I took out my iPod 5th gen to check the time and it was fine. Then I took it out 5 minutes later and it had a black screen so i clicked the home button. Nothing happened. I've tried the power button, the home button, holding down the power button, and plugging it into a charger and nothing has helped. It's still on a black screen and won't respond to anything I do. What should I do?

    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.
    - Try on another computer
    - If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

  • My iPhone 5c has a broken screen and won't let me swipe. I got a new iPhone 5c, but want my stuff to backup to it. I haven't backed my old one up in over a year because the storage is full. How would I back it up to iCloud on a Dell or Toshiba computer?

    Hi Linda Loo Loo,
    If you have backed up previously to iTunes on a specific computer, even if it has been a while, you may be able to still backup even if you are unable enter the passcode on your iPhone due to a damaged screen. You may find the following article helpful:
    If you have previously synced your device with iTunes, you may be able to reset the passcode by restoring the device:
    Connect the device to the computer with which you normally sync and open iTunes.
    Note: If iTunes asks you to enter the passcode, try another computer that you have synced with. Otherwise, go to "If you have never synced your device with iTunes, or you do not have access to a computer" section below.
    If the device is still disabled, or if iTunes does not automatically sync your device, sync the device with iTunes.
    When the backup and sync is complete, restore your device.
    When iOS Setup Assistant asks to set up your device, choose "Restore from iTunes backup".
    Select your device in iTunes and choose the most recent backup of your device.
    iOS: Forgotten passcode or device disabled after entering wrong passcode

  • When I'm on youtube and I'm watching a video, and I switch tabs or look at something else, the video from youtube will appear in the corner of my screen and won't leave.

    Alright, lets say I'm watching a video on youtube. If I switch tabs, the video from youtube will appear in my top left screen and won't go away. Or if I go to any other site or program and try to open a file from my computer, the video will pop up in the corner again and I won't be able to see anything I need to. This sounds like a glitch or something. I just need to know how to fix it.

    Does this only happen on specific pages?
    Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Firefox/Tools > Add-ons > Appearance).

  • My husband(less technologically inclined than I am), decided to delete programs from our iMac, now it has a grey screen and won't get past it. If I insert the Application Install DVD, to repair the disk, will I loose all my pictures and music?

    With a corrupt disk, the install procedure is most likely going to fail.
    How old it the disk?
    You might be able to reformat it to fix the problem. Of course that means you lose all of your data.
    The other alternative is to get a new disk drive and put that in your Mac and install OS X
    Then put the old disk drive in an enclosure and see what can be recovered from it.
