  • Black Screen, Grey Screen, then flashing question mark, now frozen....

    hi everyone,
    i know i have probably the most common problem - and i've tried to read all about the logic board problems which i'm fairly certain i have.
    I realize i will most likely have to buy a new macbook - but before i do - i need to retrieve files that are on my ibook g3 (bought in early 2003).
    This is what has happened in the past 2 days:
    1. I can hear the power start up (and chimes) but screen is completely black.
    2. Tried resetting PRAM and PMU, now blank grey screen sometimes appears.
    3. Now, grey screen with flashing question mark in the middle alternating with mac face. So i assumed this meant it couldn't locate my hard drive. So i found my ibook install disc and inserted it and restarted while holding down "C" key.
    4. Grey screen - with Apple (thought this was success) - then it turned to a large grey circle with a line through it (a slash). And then suddenly frozen.
    Since then it has just been a lot of lines through the screen alternating with completely grey screen, etc. along with any of the above-mentioned outcomes. I tried pushing on the lower-left-hand corner of the computer and yes, it affects the display - more or less lines, etc.
    How can i get my old files off of it? Do i buy a new macbook and connect them via fire wire cable and try that way? or will that not work if the above is happening? Or is it possible for someone (myself or perhaps IT professionals) to remove the hard drive from my old ibook and place it somewhere where i can copy over the files?
    Any help is appreciated - i know this is a popular topic - i've just had so many weird outcomes in the past 2 days i'm not exactly sure which solution (if any) would work for me right now.
    Thanks so much!

    Hi Ronda -
    I do have access to another mac (mini) with firewire at my work. Or I might go out and buy a new macbook this weekend as well (preferable since I don't really want my personal files on my work computer, etc.) But yes, i need to get my old files off of this one.
    I have never added additional memory or anything to it really since I got it. So it should be the original specs:
    iBook (14.1 LCD 900 MHz 32 VRAM)
    256MB memory
    Combo (DVD-ROM/CD-RW)
    Hard drive: 40GB
    Not a lot of space was remaining if i recall. I did get the 'disk full' notice a few weeks ago, but i did end up deleting a lot of stuff. Needless to say, i'm sure it was quite full, but not at maximum when this happened.
    Update: Last night i tried to start it up again, and it would ONLY go to a black screen this time (ie. no display at all). What do you think i should do?

  • Imac G5 won't start white screen and flashing question mark

    tried every key combo recomended -   erased HD using target mode/firewire with laptop - but won't boot up from install disc...

    The white screen with flashing question mark means that it cannot find a bootable volume.
    The iMac G5 will not boot from just any install disk. Ideally, use the grey restore disks which came with the computer. If you've lost these, you can order them direct from Apple. Alternatively, a Mac OS X 10.5 retail install DVD will work provided the iMac G5 has also 1GB RAM (minimum requirement for 10.5).
    Sometimes, if the internal drive is faulty, it can take a long time for the computer to recognise other disks. I would suggest holding down the option key on the keyboard (labled alt on some keyboards) and turning the computer on, keep holding alt until you get to the early boot menu, insert your DVD/CD, and click the circle arrow to refresh, wait a bit and the DVD/CD will show up and you can click on it to select it and boot from it by pressing the straight arrow.
    After a little while it will get to the install menu, select your language, then on the next screen go through the menus to find "Disk Utility" (it's in different places on different versions of Mac OS X).
    You will want to check that the internal hard drive is detected, and that it doesn't have a SMART error (it might be red, or say that the disk is failing). If you get that far, then (assuming you have erased the disk previously, as this will step really will erase the drive and take all your data with it) partition the drive, making sure that under 'Options' you select Apple Partition Map (this will be the default on earlier versions of Mac OS X, but might not be if you've erase the disk from an intel Mac like a MacBook).
    Once, you done all that, and there haven't been any issues, you should be able to quit Disk Utility, and carry on with the sytem install as usual, and a 30mins to 2 hours and reboot later you should be booting from the internal drive again.

  • Why won't my MacBook Pro start up? White screen and flashing question mark.

    Hi,
    I've had my MacBook Pro for almost 2 years now and I installed OS X 10.8 about 4 months ago.
    Today I turned the MacBook Pro on and a white screen with a flashing question mark appeared. I tried then getting the startup manager up: turning on the laptop and immediately holding in alt (option). But nothing appeared for about 25 seconds until a rotating Earth labelled 'Internet recovery' appeared that gave me options to join wireless connections. However, my internet wasn't in the options and when I tried typing in the information required to join my internet the laptop would just load and never find it.
    I then tried putting in my Mac OS X install DVD (10.6.7) and help in C until the apple logo appeared on the screen and the little rotating loading circle appeared. That then disappeared and a cicle with a cross through it appeared (similar to a no entry sign). Then after about 30 seconds a blue screen followed by a grey screen appeared until eventually the disc ran properly. I then went into Disk Utility but there was no option called Macintosh HD, only the discs content. It wouldn't let me first aid, erase or repair anything.
    I'm totally stumped and have 4 exams at university within the next 2 weeks. I'd really appreciate it if anyone could help me out here?
    Thanks,
    Best wishes,
    Connor

    The support article linked below is somewhat outdated. Where it refers to starting up from an installation disc, you should instead start up in Recovery by holding down the key combination command-R at the chime. Release the keys when you see a gray screen with a spinning dial.
    If you don't have a current backup of all the data on the startup volume, and you want to preserve that data, then you must try to back up before you do anything else. Ask for instructions if you need them.
    Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to reinstall OS X from Recovery, if necessary. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.

  • Assistance with Disk Warrior and Flashing Question Mark

    Hello, guys!
    I need a help. My computer was not booting and kept flashing question mark. I've tried First Aid, didn't help. Then I've checked with Apple store technicians, after all they reccommentd me to run Disk Warrior v.4. I did, but it couldn't create a directory for the files. What does it mean? What would be next step?
    Thank you very much for any advice.

    Hi, Olimpia. If your hard drive's directory is very, very badly damaged, DiskWarrior may not be able to reconstruct it. Did you see an error message in Diskwarrior that said something like that? If so, you have no choice but to use something like Data Rescue II to recover what files it can, and then erase and zero the hard drive and start over.
    If you didn't see any error message, but Diskwarrior seemed to be taking a very long time and didn't appear to be doing anything, it was probably still working and just needed time and patience. I've seen several reports of Diskwarrior successfully rebuilding badly damaged directories but taking several days to do it, and one instance when it successfully completed a rebuild after *14 days* of continuous work. If it doesn't show any error message, just let it keep on working.

    If you are running Snow Leopard:
    Reinstall OS X without erasing the drive
    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.
    Download and install Mac OS X 10.6.8 Update Combo v1.1.
    If you are running Lion or later:
    Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Repair
    When the recovery menu appears select Disk Utility. 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.

If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.

    OS X Mavericks- Reinstall OS X
    OS X Mountain Lion- Reinstall OS X
    OS X Lion- Reinstall Mac OS X

  • White screen with a folder and a question mark in the Folder

    Hi,
    My daughter's Desktop Mac Pro won't reboot. On reboot, it shows a white screen with a folder and a question mark within, It just stays there and nothing happens. Is this a problem with a dead hard drive, dead processor, faulty USB connection, problem with airport.? We need advise and help, please!
    effie imperio

    Hi, Anonymoustache, thanks for responding.
    Yes, I think it is "a flashing question mark". If it is flashing, you think it is a hardware problem like a dead hard drive? I had a flashing question mark with my Power book G4 and Apple replaced a dead hard drive.
    Thanks Hatter, I will convey your response to my daughter and see if it will help.

    Can you still boot to the Recovery partition using Command and R whilst booting? Or did you wipe the Recovery partition as well?
    If your Recovery partition is still intact, you can simply boot to it and reinstall the OS via the Internet. If you wiped the Recovery partition, you can hold down Command, option and R keys whilst booting and boot into true Internet Recovery mode. You'll be able to reformat the hard drive, erasing all partitions (format it as "Mac OS Extended (Journaled)" with a dingle GUID partition) and then reinstall the OS that shipped with your machine.
    Note that you should use a physical Ethernet connection when restoring over the Internet - it's three times slower if you use wifi.
    Try your Recovery partition first and if that doesn't work, use Internet Recovery.
