    Your saying it's always a chime and black screen now every time your restart?

     

    What happens when you hold down the Shift key  or the Option key when you restart?

    ................................................................................ .................................................................

    Reset the PRAM- Hold down the Command/Option and P  R keys at the same time at startup.

     

    To reset your computer’s PRAM:

    1.   Shut down the computer.
    2.   Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    3.   Turn on the computer.
    4.   Immediately press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.

      Continue holding the keys down until the computer restarts, and you hear the startup sound for the second time.

    5.   Release the keys.

     

     

    Resetting PRAM may change some system settings and preferences. Use System Preferences to restore your settings.
