Past few weeks my imac has been playing up, every so often during the day the spinning colour whell appears and locks me out for a few seconds, annoying but to busy ti investigate as it goes away and returns at random, today it stayed and I had no alternative than to turn machine off and reboot, the white screnn appeared with the apple logo and the alternating segment timer but then the logo was repalced with a circle with aline through, the timer is still doing laps but nothing changes, the mahine was bought new 18 months ago but I'm not sure of exact spec? can anyone help?

Regards

Steve

    Hi Steve,

     

    "Try Disk Utility

     

    1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.

    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)

    *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*

    3. Click the First Aid tab.

    4. Select your Mac OS X volume.

    5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."

     

    http://docs.info.apple.com/article.html?artnum=106214

     

    Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.

     

    (Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)

     

    If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.

     

     

    If 10.7.0 or later...

     

    Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.

    The next time you have the problem, note the exact time: hour, minute, second.

     

    If you have more than one user account, these instructions must be carried out as an administrator.

     

    Launch the Console application in any of the following ways:

     

    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

     

    ☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

     

    ☞ Open LaunchPad. Click Utilities, then Console in the icon grid.

     

    Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select

    View Show Log List

    from the menu bar.

    Scroll back in the log to the time you noted above. Select any messages timestamped from then until the end of the episode. Copy them (command-C) to the Clipboard. Paste (command-V) into a reply to this message.

     

    When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.

    Please do not indiscriminately dump thousands of lines from the log into this discussion.

     

    Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
