    Insert your Mac OS X disc and then power on the computer, once your hear the "bong" sound hold down the "c" key until it presents you with the Mac OS X language selection screen. From there it is pretty straightforward to install the OS :)

    Go to the Utilities menu and open Disk Utility. Your drive should show up on the left. Click it and hit Erase then format with HFS+, journaling doesn't really matter. Format.

    Then try your install.

    What they said ^

    Just boot from the CD, When it boots select erase as HFS+ and then go through the steps for installation. It should take around 20 minutes.

    Load the OS X DVD as already said, and open Disk Utility. If this is a brand new drive you installed, most likely it has no partition scheme, so you will need to set a partition scheme before you can format it. To do this, follow the directions after opening Disk Utility:

    After you complete the these steps, you can close Disk Utility and continue installing OS X.

    Thank you everyone so much. I'm a first time Mac user with little knowledge of the OS besides basic functions so I was really stuck. Now I am happily running my laptop with 4 Gb RAM and a 500Gb HD! Thanks, and happy Mac-ing!
