30gb Ipod not Working

ok so i've been using windows 7 for a few months now and since i started using it my ipod worked perfectly with it. i recently got a new graphics card for my computer (the only change to my computer since switching to windows 7). my ipod worked even then. butfor the past 2 weeks whenever i try to connect my ipod to my computer, i get a message saying my computer doesn't recognize the device. i look in the device manager and it comes up as unknown device. i run troubleshooting wizards and it gives me this explanation for the device: "Windows has stopped this device because it has reported problems. (Code 43)"
my ipod worked one day earlier this week but once i restarted my computer it wouldn't read it again.

What do i do?
