Please help me to help you,
I need to know if you connect the iPod to the PC, or wall charger, did the iPod screen shows any life, like
- the Battery Charging icon
- Do Not Disconnect sign
If you don't get any of these display while connected to the PC it could be
- The USB Cable is no good (but then you also used the wall charger)
- The iPod dock connector at the bottom, is fouled up with lint or dirt (try to clean it up)
- The iPod LCD display is dead
- The iPod is dead, maybe when it went for a swim.
But do bring it in to Apple store for the Genius to have a look, since it is slightly older than 1 year.
With the limited info from you,
I can only suggest you to do a Hard Reset
- Charge your Ipod for at least 2 hours
- Toggle the Hold switch, make sure you dont see the Red mark when you do the next step
- Reset the iPod -> Press Menu and Center button simultaneously for about10 secs till the Apple Logo comes ON
- Then release the buttons
- Select your preferred language.
