How to reset the root password

I forgot the root password of my iMac that I dedicated to my children, for a long time, now, I came to use it and found it very slow and unresponsive, and I need to log in using the terminal and write unix commands to find out the real problem, but could not remember the password to root probably I created seven years ago.

as I remember that I needed to have the CD and reboot the system with the recovery disk, but I couldn't get there, shut up always back to the default disk.

Any help is appreciated?

Thank you

    Unfortunately, business machines such as Probooks or EliteBook have more strict security consumption patterns - they do not produce "stop codes", the password cannot be derived from the serial number and the code is stored in a nonvolatile memory to remove the RTC cell does not reset the password in this case.

    and here you can find an instruction how to use this disk to reset the password:
    http://www.Vistax64.com/tutorials/102005-reset-user-account-password.html
    But note; the password reset disk can be created if you would be able to connect to Windows Vista.

    But if you would not be able to create the password reset disk, then you can try using the three method which is also described in the statement.
