My Ipod touch 5th generation does not come up on my computer or my itunes, it won't even charge when it is connected to the computer, I can not sync any of my music.
It was previously on another computer, so i restored factory settings and tried to sync with the new computer and it wont come up.
iOS: Device not recognized in iTunes for Windows
I would start with
Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8
Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP
Run this to help if it identifies the cause
iTunes for Windows: Device Sync Tests
Have you tried on another computer to help determine if you have a computer or iPod problem?
