Q: I have a new computer, how do I sync my Ipod Classic to the new computer

Your iPod is designed to sync with only one iTunes library at a time.  It will recognize the iTunes library on the PC as a new library.  If you sync the iPod with this new library, all content will be erased from the iPod and replaced with what is in the new library.  So what you will want to do is copy everything from the iPod to your new iTunes library on your PC first.

Or better yet, if you still have access to the old computer, use one of the method described in this article copy everything from the old PC to the new one.
