I have an issue. Just happened yesterday. When I click on the button behind my iMac to power it on, it doesn't go on. First it made that chime sound it does when it powers on. Then the apple icon came on with that circular timer turning. Then I saw a picture of a hard drive with a little arrow under it, so I can click. Then all of a sudden the screen turned off. Went black. I click on the power button again and it makes the chime sound again. Apple icon comes out with timer spinning then the screen goes off again. Computer turns off. What can this be?

    Do you have an installer DVD for the machine? If you do then see if you can boot from it without the same thing happening.

     

    If you have a machine with Lion or Mountain Lion pre-installed then try booting from the Recovery HD.

     

    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.

    I have no disks at all. When I bought the iMac at Best Buy it didn't include any disks. Maybe because they pre installed it so I can basically get home, plug and play. But this computer is about 2 years old.

    And, what version of OS X is installed?

    I can't remember now. ****! See I can't turn it on to check. To be honest I don't recall. I guess I have the one it came with originally 2 years ago. I know this isn't much help.

    If you never upgraded it, then most likely it came with Snow Leopard. Two years ago makes it a 2010 model, I'm guessing. In that case you should have received a set of two DVDs. One would have been the OS installer disc. The other contained the bundled iLife applications. Best Buy must have sold you a demo or floor model on sale but didn't give you the discs for it. They owe you those discs. Otherwise, you will have to purchase replacements from Apple - Contacting Apple for support and service - this includes international calling numbers.

     

    Meanwhile you can take the computer to Best Buy for repair because without the installer disc there isn't a whole log you can do. Do you happen to have a recent functioning backup?

    OK just called Best Buy and they said I bought in January 2011. Will it still have that Snow Leopard? If that makes a difference. The Geek Squad guy said it sounds like it could be the motherboard but he isn't 100% sure because I need to take it in for a check up. Functioning back up? No. I never did that =(

    Well, that would make it a 2010 model, so if you haven't upgraded, then you would be running Snow Leopard - 10.6.3 or 10.6.4. Naturally, they will say it's the motherboard without testing in order to prepare you for the worst case scenario.

     

    The first thing to do is take it in because you don't have an installer disc. Be sure they first try booting it from an installer disc. If it does the same thing, then there's a hardware malfunction. I assume you did not buy the extended warranty, so if it is a motherboard replacement, then be prepared for a hefty repair bill.

    Yeah the guy scared me a bit saying that it could run up to $700 or $800. That's pretty scary considering that a couple of  hundred dollars more I can get a brand new one "/

    If you still have your original box then you may still have the install discs and not even realize it. The install discs are stuffed behind the tiny little 5" X 5" 'Everything Mac' user guide that is dropped into the cutout on the top of the foam block that you had to remove. Unless you are specifically looking for the discs they can be easy to miss.

     

    Here's an article that may be helpful, although you really need either a bootable external hard drive or install DVD to troubleshoot further. Disconnecting all attached peripherals besides the keyboard and mouse is also a good idea in case one of them is causing the issue.

    I actually do still have the box in my garage. I'm going to take a look in there and post here what to do in case I do find it. The mouse and keyboard are Bluetooth. Will that cause an issue as well?

    Having a wireless mouse and keyboard should not cause any issues of the type you are experiencing. I do suggest temporarily disconnecting any other devices you have attached just long enough to rule out whether they are contributing to the issue.

     

    If you locate the install discs in the box then you can attempt to boot from the install disc by powering on the system, then immediately hold down the option key to bring up a list of bootable devices. The install DVD should appear. Another option is to hold down the 'C' key which will attempt to boot directly from the optical drive instead of bringing up a list of bootable devices.
