Reset The Password To The Administrator Account
If you have lost the password to the original administrator account, than you will need an OS X disk to reset the password. More than likely it will be "install disk 1" that should have came with your computer when you purchased it.
Insert the disk into the drive and restart the computer. As soon as you hear the chime when your computer is booting up, hold down the "C" key. If the "C" key does not boot from the disk, than try holding down the "option" key instead.
Once you have booted from disk, the OS X installer window should be on screen. Go ahead and click continue in the first box that pops up. Next, look at the toolbar located at the very top of the screen. You will see numerous options. Choose either installer menu, or the apple menu (depending on which OS disk version you are using). Under one of the top menus, you should find an option to reset your password. After you have selected reset password, it will ask you to select your hard drive. Select the hard drive and select your administer account name from the dropdown menu. Enter your new password, verify and click reset.
