    Is your brightness too low?

    I doubt this is the advice that Linc gave, but you could try an SMC and PRAM reset:

    iMac SMC and PRAM reset

     

    Also, you could try a Safe Boot: restart holding down the Shift key until you see a grey progress bar, input your Admin password when prompted and let it fully boot. Once booted restart as normal from the Apple menu and test.

    This worked: Although this has happened before and I am frustrated...Do you think there is a problem with my computer???

     

     

     

    For those that the quick fix couldn't help.

     

    Shut down the computer, wait ten seconds. Boot up holding down Command and S.

     

    Release the keys once you see a black screen with white text. When the text stops, the bottom line should be

    root#

     

    Type in the following lines, after each line hit the return key.

     

    mount -uw /

     

    cd /Library/Preferences                                 

     

    mv com.apple.loginwindow.plist oldlogin

     

    reboot

     

    Once computer is rebooted, wait a few seconds if you are still getting the black screen, click around with your cursor.
