My ipod has a picture of the usb cord connecting to itunes frozen on the screen and itunes will not recognize the ipod.
iPhone, iPad, or iPod touch: Device not recognized in iTunes for Windows
Were you doing anything when the iPod went to the screen?
I was trying to update and install the new itunes. My computer will not let me update itunes, it keeps saying invalid signature. Since then the ipod has been frozen.
