My Ipod restarts when I plug into my PC.

I've got an Ipod Classic (120Gb) and I recently dropped it while it was connected to my PC. It disconnected from the PC when it was dropped and now when I plug it into my PC it just restarts. Whenever the Ipod connects to the PC it keep restarting. I cannot play any music or podcasts now either. Is there any way to do a factory reset or reformat without connecting the Ipod to the PC? I don't care if I lose any info on the Ipod itself as I just want to get it working again.
