There is no need to format the drive. However, as you have the full
version you have the option, as other have said, to upgrade or clean
install. I certainly wouldn't be looking at an upgrade. Do a clean install
instead. If you need any guidance with the installation process you can
find an illustrated guide to installing Vista on my website:

Alternatively you can also find an illustarted guide to upgrading too at:
http://vistasupport.mvps.org/upgrading_to_windows_vista.htm
upgrading does, however, take some hours. The last time i did it it took 4
hours plus.
