ipod nano query

[mjulian]

Can anyone help me please? I've got a 4 year Ipod Nano which has suddenly gone berserk! When I switched it on, the screen showed all the tracks whizzing by and I couldn't switch it off. I've recharged the battery and restored it to factory settings BUT I keep getting a message telling me that it is in recovery mode and I need to restore it! I've done this now 4 times - I've switched the ipod and the pc off and on again. The online help menu doesn't explain what to do to get out of this circle. Can anyone suggest anything [not rude!] please. Many thanks.
