    3 ways to go...

     

      1. Insert the Mac OS X Install disc that came with your computer, 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. (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 Erase tab.

       4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.

       5. Select your Mac OS X volume.

       6. Highlight the drive, select Partition Tab, then Format type... MacOS Extended Journalled, select the Security Options button, choose Zero Out Data, Erase... after completion do a new install.

     

     

    Or...

     

    Open System Preferences>Accounts, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.

    In the same pref pane highlight your old account, click the little minus icon, then use Disk Utility to Secure Erase Free Space.

     

     

    Or...

     

    If 10.7.0 or later...

     

    Bootup holding CMD+r, or the Option/alt key to boot from the Restore partitiion & use Disk Utility from there to erase & reinstall.
