Zapping the PRAM

Zapping the PRAM (Parameter RAM) resets the PRAM settings back to their default values. Resetting the PRAM may be helpful if your computer is having startup problems, or other miscellaneous problems. For more information on what is stored in the PRAM settings, view the following Apple article:

To reset the PRAM, do the following:

Step1: Shut down the computer
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to use these keys in the following next step.
