My imac is stuck at the loading screen and wont start up...

My 2006(ish) Intel core 2duo 2.16 mhz 20"  imac wont start up, it only stays at the loading screen, how can i fix this?

Since you purchased your iMac long before the Lion OS was released your system should have come with a set of DVD's that can be used to reinstall the OS and applications. If you can locate those disks then stick the Install DVD into the optical drive, then power on the system while holding down the option key. Your system should boot with a menu showing the bootable volumes. After a few seconds you should hear the optical drive whirr and then see the Install DVD appear in the menu. Select the Install DVD and boot the system. Once booted you will have to select your language. Normally this disk is used to reinstall the OS, however for this exercise I would like you to pull down the Utilities menu in the menu bar and select Disk Utility. You can use the Disk Utility to check whether your hard drive is OK. If it fails the SMART (Self Monitoring Analysis, and Reporting Technology) status then you will need to replace the hard drive. You should also run the 'Verify Disk' and 'Repair Permissions' options if the SMART status indicates the drive is passing.

  • My White Macbook is stuck at the loading screen, and disk utility, safe mode doesn't work either. What should I do?

    I went on vacation a few days ago and in El Salvador, they have this mobile broadband sticks. Well, I was using one until it gave me a network error. After that, it shut down my computer entirely. The first time it happened, I didn't think much of it. I took the battery out and put it back in for it could work. It happened another two times, and after the third time, my MacBook stays stuck at the loading screen, and it will take 5-10 minutes on that screen, before it shuts down, or it wouldn't turn on at all. I've tried booting into safe mode, but it appears to not boot into it. I've tried resetting the Pram, and using disk utility, but that still won't work. I don't know what else to do to make it boot into  OS X  Lion.
    I'm an AP student, and the majority of my work is in that computer, and it is very important! What can I do? Not only that, but I enter school in a few weeks and I need the AP work by the time I enter.
    What can I do? Can someone help?
    Thanks

    Reinstalling Lion Without the Installer
    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. Alterhatively, 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 the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
    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. (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 main menu.
    Reinstall Lion: Select Reinstall Lion and click on the Continue button.
    Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.

  • My MacBook Pro is stuck on the loading screen and sounds as if its about the take off?!

    Hi everyone. About 3 hours ago my laptop suddenly became very unresponsive and began freezing a lot. I cleared the cookies on Firefox, but the problem carried on so I tried rebooting. Now it has been stuck on the loading screen for about half an hour, sounding like a rocket ready to take off.. I brought it second hand and I don't have an installation CD, at least if I do it's not here at uni with me anyway.. Any ideas?! Thanks

    Not knowing what your os is very difficult regarding offering troubleshooting solutions.  Most if not all the system discs are machine specific. 
    Replacement System Discs can be obtained from Apple's Customer Support - US (800) 767-2775 for a nominal fee. You'll need to have the model and serial number of your Mac available. 
    If you're not in the US, you may need to go through the regional Apple Store that serves your location to find the contact number - http://store.apple.com/Catalog/US/Images/intlstoreroutingpage.html

  • Updated 5c to 8.1.3 but its stuck on the loading screen and has been for hours

    I updated my iphone 5c to the 8.1.3 and its been stuck on the loading page for hours now. I've tried pressing buttons and unplugging it but it won't do anything.

    "Pressing buttons" is vague, make sure you've tried a reset:
    Hold both the home and power buttons at the same time until the Apple boot logo appears.
    If that does not work you may need to restore the phone: see http://support.apple.com/kb/HT1808

    Try:
    - Reset the iOS device. Nothing will be lost
    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Restore from backup. See:                                                
    iOS: How to back up                                                                                     
    - Restore to factory settings/new iOS device.             
    If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.
    Apple Retail Store - Genius Bar                                      
    If necessary try the remaining items of:
    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 another cable
    - 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 is now stuck on the loading screen and keeps blinking. I dont know if this is because of the new update but is there anyway I can fix it?

    Yes can someone please HELP!!

    Try plugging it up to your computer and launching iTunes and either resetting it to factory settings or resetting to last sync. Hopefully it just noticing it's plugged up to iTunes will fix it. This happened to my friend once and all she had to do was plug it into her computer and that fixed it.

  • I tried to update my iphone 4 to i07 but it's now just stuck at half way on the loading screen and I cannot get it to do anything

    So like a moron, I made the mistake of finally updating my Iphone 4's OS to the new one that Apple has been bugging the crap out of me about for months now. The problem is, my phone is now stuck on the loading screen and I cannot get it to do *ANYTHING*. It won't connect to my PC, Itunes won't let me get on it without the pin lock being entered on the phone which I CANNOT do because the phone is stuck on the update screen.. and Apple won't talk to me for help because I cannot get them the serial number which I CANNOT do because my phone is stuck on the update screen!
    Is there no way to just take the battery out or something? I looked for screws but they seem to be proprietary (because of course they are, because Apple) How do I force it to get off the update screen?!

    If you open it to take out the battery from the iPhone then you forfeit all service for whatever reason from Apple in the future.
    Have you attempt to connect it to your computer and then restore it from iTunes on your computer?

  • My Macbook is stuck at the loading screen (the apple with the spinning circle beneath it). I went to Best Buy, they told me to call Apple Help and ask them to restore my unit. But Apple help wont help me without charging me. Help please !!

    My Macbook Pro is stuck at the loading screen (the apple with the spinning circle underneath). I went to Best Buy to get help, and they told me to call Apple Help and ask them to 'restore my unit', which he said is a matter of only about 4 mouse clicks. If it was so easy, I didn't understand why he couldn't do it for me. But he said that even though I have a 3 year warranty and protection plan with them, they were not responsible for this type of problem. Whatever.
    Anyway, so I called Apple Help, and even though he was familiar with my problem, it's been more than 90 days since I purchased the laptop, therefore I'd have to set up a service agreement to get his assistance, meaning I'd have to PAY him. So now i'm stuck, and I'm just hoping somebody knows what to do to help me
    I don't have any disc that I apparently need, and I don't remember ever getting one. However, if there is some other way to fix this issue, please let me know. Thanks for your time and assistance
