Have you installed the iTunes programme on your computer? You need iTunes to manage your iPod. Download it from http://www.apple.com/itunes/ and then install it.
Have you copied your music from the old computer to an external hard drive so that you can import it into the new computer? You cannot copy the music from the iPod to a new iTunes Library (or at least, you can't do it easily!)
