Computer 1: Asus P4C800-E Deluxe, P4C 2.8 GHz, 500 watt PSU Computer 2: Asus P4P800, P4C 2.8 GHz, 400 watt PSU I plug the iPod Nano into PC1 and nothing happens. Restart the computer and go into the bios. In the bios it recognizes the iPod Nano. Go back into windows. Still nothing. Nothing in control panel, nothing detected through iTunes, etc. I plug it into PC2 and it detects automatically and asks me if I want to synch. Problem is all my music is on PC1. What could be the problem?
