If you have the 64 bit version of the Install DVD, you will need to reinstall the OS. You cannot upgrade over a 32 bit install with a 64 bit one.

Make sure and backup all of your personal data you can since the drive will be formatted and all of your programs will have to be reinstalled, unless they are on an OEM type install.

If you have specific questions, please post back.
