Problems Syncing iPod to XP

> I have a 40 GB (third generation) iPod and a PC upgraded from Windows
> 2000 to XP. I'm connecting via firewire, using a card that I installed
> myself. It worked fine with 2000, but since I upgraded, I've had
> frequent problems syncing. I'll put the iPod in the cradle and iTunes
> will open, but then freeze up. If I run the iPod disk repair, it works
> fine, but then a few days later it starts freezing again, when all
> I've done in the meantime is listen to music.
>
> My iPod, XP, and iTunes all have the latest software. I've tried
> wiping the ipod and restoring the software, but that doesn't seem to
> help.

> Any thoughts?
