My iMac crashed once and so I held the on/off button and it was fine. It did it again while I wasn't around and my mum unplugged it from the socket.

So my iMac crashed - just left normally with safari while I was listening to music on Pandora and suddenly the screen became full of fray lines and nothing could be seen or done. I then had to force it off by turning it off from the on/off button at the back. I then turned the Mac back on and it was working like normal. I turned it off that night.
My mum then turned it on and was playing spider solitaire like she always have. The same thing then happened to (while I was not around). She does not know much about computers and she couldn't turn it off after a while so she decided to then turn it off by unplugging it from the powerpoint/wall socket. It then would not turn back on.
Whenever I try to turn it on I can hear the usual clicking sound of the CD/DVD side, but nothing happens, it's just a blank screen.
What should I do? I've had this iMac for about 2.5 years almost 3 years now and this only happened last night.
Please help??

Ok so it turned back on, and after leaving it on for less than 30 minutes and was not running any applications and it suddenly turned to a black screen and when I touched the back of it, it was completely boiling. Could it be that something is wrong with the fanning system? If I have purchased this iMac for almost 3 years already. Would I still be able to bring it out to the apple store and have it looked at?
Would I have to pay anything to have it fixed by the apple store?

    Try to reset it by holding the power an home buttons at the same time until you see the Apple logo, then release.  If it won't reset, you'll probably have to force it into recovery mode and restore it, as explained here: http://support.apple.com/kb/ht1808.

    Tom:
    I performed the steps indicated but this morning when I clicked the mouse and hit the space key and clicked the track pad again as before nothing happens.
    I hold the power button for a few seconds and the screen fills as if the computer was normally awakened but it is locked up.
    Then I have to shut it down with the power button  and then power it up as a reboot.
    Not good...SMC reset didn't work....Throughout the day yesterday I put the computer to sleep and woke it up normally.  It seems to be a overnight problem.
    Am I going to have to shut it down everynight?

  • My Macbook will not boot the operating system.  It just goes to a blue screen after the apple logo and the spinning wheel goes off.  I took the battery out and held the on/off button for five seconds and reset the PRAM.  I have the old mac os disk.

    My macbook will not boot.  It goes to a blue screen after the logo and wheel goes off.  I have taken the battery out and held the on/off button for five seconds and reset the PRAM.  I have the the original os disk but have not put it in for fear of losing un backed op data.
    Thanks

    You won't lose any data unless you erase your hard drive.
    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.
    When it does start up, you'll see a panel asking you to choose your language. Choose your language and press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it.When it comes up is your Hard Drive in the list on the left?
    If it is then click on the Mac OS partition of your hard drive in the left hand list. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've selected the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions.

  • I am getting a message in the middle of my imac screen instructing me to hold down the on-off button and turn off the machine. The message is in several foreign languages beside english, and there is not way to get rid of it. The curser is inactive.

    I am getting a message in the middle of my imac screen instructing me to hold down the on-off button and turn off the computer. The message is in several languages and completely takes over the computer disabling the mouse and all other functions. The only option is to unplug the computer or turn it off. I'm concerned that this is a virus. It does not look like it's related to Apple or the imac OS.

    That sounds like a kernel panic. These are generally hardware related, often caused by poorly seated or fauly RAM.

    Try to boot in Safe mode, see if you are able: Hold down shift and then power on. For wireless keyboards, hold down shift after the chime.

  • How to Create a Bootable Flash Drive to do a clean install of Lion.  I have tried to use the InstallESD.dmg but it still will not do a clean install so that I do not have to do a reinstall from the Recovery (That just re downloads and takes over 6 hours)?

    How to Create a Bootable Flash Drive to do a clean install of Lion.  I have tried to use the InstallESD.dmg but it still will not do a clean install so that I do not have to do a reinstall from the Recovery (That just re downloads and takes over 6 hours)?
    The system I'm have is a Mac-mini that had SL on it and no SuperDrive.  I have also call Apple Support and they have really have not been to much help over 1st did my up grade to Lion and Installed the Lion Server.... it lost my SSL that I paid for and kill almost on of my server setting, plus kill all my web servers (using apache vhosts), and not to say the LDAP will even let remote users login to your laptops.
    PS: There is no way that I'm going to buy a Install USB from Apple... They have over billed me over $300.00 because the Apps Store still has bugs (Glad I did not write that App/Service)
    If there is anyone that can give in the information to create a USB install stick, I would be very thinkful.

    Here you are bro, courtesy of "softpedia.com"....brilliant site!!!
    If you ever had problems with your Mac OS X installation you know that the first thing you should do is to check the startup volume using Disk Utility.
    After the check has ended and, if the errors exceed a certain level of seriousness, the Disk Utility application will require you to restart your Mac and use its Mac OS X Install disc counterpart.
    Other users may have to reinstall OS X altogether, but will find, or already know, that their SuperDrive (a CD/DVD reader and write combo drive) is not functioning properly and it will not be able to read the Install disc.
    Although this might happen to Mac OS X Leopard users due to faultyhardware, the vast majority of problematic SuperDrives will be encountered inside Snow Leopard running Macs.
    This is due to the updated SuperDrive firmware included in either the Install disc or the software updates one has to install to reach the latest version of OS X, namely 10.6.6.
    This can be fixed by flashing the SuperDrive’s stock firmware using free command line tools that one can find for free online (I will write about this process also, but at a later time because this article only focuses on allowing you to create your own alternative USB boot disc).
    If you are reading this last bit of information with skepticism, than you should know that it happened to me too. Despite all my tries to make it work properly, the SuperDrive kept on munching any inserted DVDs and just popped them out in about twenty seconds.
    The workaround to this issue was to create my own Leopard bootable USB memory stick. I am not suggesting a Snow Leopard bootable stick mainly because there are lots of users that have decided to buy the cheaper, Upgrade version, which I have not tested and, therefore, I’m not sure if it will work properly once written to a USB disk.
    And now, here are the exact steps you should follow in order to obtain a fully bootable Leopard (or Lion) Install disc.
    Step 1 (If you already have the Leopard install disc DMG file you can skip to Step 2)
    Launch Disk Utility (you can find it inside /Applications/Utilities). Here select the Leopard Install disc in the list of drives on the left and click on the New Image menu entry at the top of the window. A save message will appear where you will have to select the Desktop as a destination.
    Step 2
    After Disk Utility has finished creating the Leopard DMG, insert your USB stick and erase all data and reformat the disk. To do this select the USB in the list of drives on the left and, after clicking on the Erase tab on the right side of the window, choose the Mac OS Extended (Journaled) format and click the Erase button beneath.
    Step 3
    After the USB has been reformatted, download the SuperDuper app from HERE and launch it. Once SuperDuper starts, you will only have to select the DMG in the Copy drop-down menu, your USB memory stick on the right and hit the “Copy Now” button.
    One can also use Disk Utility for this task but creating a bootable USB stick failed 2 out 4 times when copying the DMG to the stick (with the exact same settings each time). Creating the bootable stick using SuperDuper proved to be the perfect way to do it because it worked each of the 4 times I tested it.
    The steps above can also be used to create a bootable Mac OS X Lion USB by using the InstallESD.dmg image you can find inside the Lion installer (named “Install Mac OS X Lion.app”) downloaded from the Mac App Store in the /Applications folder.
    To locate the InstallESD.dmg right click the Lion installer, select the “Show Package Contents” entry, go inside the “Contents” folder, and from there into the “SharedSupport” folder. Inside this folder you can find the InstallESD.dmg you can use to create your own bootable Mac OS X Lion USB stick. To do so, go to the third step described above and use the InstallESD.dmg as the DMG to be copied to your USB disc.
    That’s it! Once the process ends you will have a fully bootable Leopard (or Lion) USB disk that you can use as an alternative to the Apple’s DVD Install disc that comes bundled with all Macs.
    To use your newly created bootable disk you will have to restart the Mac, press and hold the OPTION key until the StartupManager appears. Here, select the Mac OS X Install disk using your keyboard arrows and press return to start from the selected drive.

  • HT4410 I have just installed Windows 7 64-bit full version Home Premium using Bootcamp and cannot get access to the internet. I installed on a Macbook Air Mid 2012 with Mountain Lion. Are there some drivers that are missing from the Windows 7

    Dear Apple. I have just installed Windows 7 64-bit full version Home Premium using Bootcamp and cannot get access to the internet. I installed on a Macbook Air Mid 2012 with Mountain Lion. Are there some drivers that are missing from the Windows 7 bootcamp install download from Apple

    It is a Total Misconception that the Support files are installed when you are installing Windows, even if the USB drive that holds them is inserted in the system when doing the Windows install.
    You must always Run the Setup.exe files from the support files or run the drivers individually once Windows has finished installing and booted to the desktop.
    Also you really need to run the Boot Camp Control Panel Applet and check for updates as not all the newest drivers for full function of all the hardware is included with the original support download. That download is basically a generic version to get the system working and without doing the updates not everything will work properly.

  • IMac freezes.  Can only start up through on/off button

    I have an iMac (2006) the white one.  For the past month or so, I've noted a horizontal line across opened pages (safari) and more often with videos.  The computer freezes during the loading of some videos and the only way to restart the computer is by holding the on/off button.  The control-alt-delete doesn't work.
    Sometimes the mouse freezes too and the circular rainbow cursor just keeps going and going.
    The problem started about a month ago and I have since updated to Snow Leopard hoping it would resolve it, but it hasn't.
    Any thoughts?
    Thank you.

    do you have the discs that came with the imac still?  if so run the apple hardware test.  you could be having an issue with some bad ram or a video problem.

  • How can I assign a function to the on/off button on my imac?

    The on/off button on my imac used to turn the computer off. After a re-install, now the button just turns the computer to sleep mode. I don't remember how I had reassigned the function to the on/off-button on my imac. Any solutions? Thank you very much!

  • I cant get my i pad off. when i hold the on/off button and swipe it off it acts like it is in a loop. it wont do anything.

    I can't get iPad off. It is like in a loop. When I held the on/off button and swipe it just does nothing.

    Try rebooting your iPad.  Press and hold BOTH the power and home buttons at the SAME time for at least 10 seconds (ignore the red slider to shut down) until the Apple Logo appears, then let go of both buttons and your iPad will restart.  See if you can shut down then......

    All I can suggest is that you open that file on the MBA and save it as a new file, then see if you can open the new one on the iMac.

  • TA44551 My 1-year ipod nano locked up and would not start overnight. The on/off button will not work and stopped holding charge. No water damage, no fall, nothing unusual. I restored it (twice) but it will still not hold charge and on/off does not work.

    My 1-year ipod nano locked up and would not start overnight. The on/off button will not work and stopped holding charge. No water damage, no fall, nothing unusual. I restored it (twice) but it will still not hold charge and on/off does not work. I tried to restore it again and charged it in three different locations with different cables. etc but nothing. Suggestions?

    - After charging for 1/2 hour or so, does iTunes see the iPod?  If yes, restore the iPod from backup.
    - If no, se if placing the iPod in recovery mode will make it visible so you can restore the iPod.  For recovery mode see:
    iPhone and iPod touch: Unable to update or restore

  • My home screen is gigantic. As a result I cannot see the keypad for entering in my passcode. Somehow, everything on my home screen has expanded to gigantic size. I've tried to reset the phone by holding the home button and the on off button...

    My home screen is gigantic… So much so that 1/200 of the normal screen display now fills up the entire screen. As a result, I cannot even see my keypad to enter in my passcode. I've tried a hard reset a few times (holding the home button and the on off button at the same time until the iPhone restarts). This has not resulted in any changes. Any ideas?

    Thank you Lawrence. that worked! I have another question for you as well. I just got this 6 Plus and it is already saying that I am nearing the end of my storage. My  iCloud is apparently 20gb and I have 6gb left. I'm attaching a screen shot. Any thoughts on how I can make available some more storage?
    I Also wanted to get an enhanced quality Speech voice Alex, but it is saying I don't have enough Memory (I think it says memory because I can't read the message fully). Lastly, in your opinion does Grayscale really improve battery life above and beyond what can be achieved by closing out all apps etc. Thank you.
