Ipod Nano 4th Gen not recognised in Windows Vista, Windows 7 or Itunes and screen blank

Hello,

I have a quite old (3-4 years old) iPod Nano 4th Gen.

The screen is blank, which means it needs charging. When I plug it into my laptop/computer then it doesn't show up which im assuming is because it needs charging.

When I plug it into my plug charger (plugged into a wall) nothing happens.

I think this is because the cables (I have 3- 2 computer USB cables and one plug charger cable) being too lose and not connecting to the iPhone fully.

I have looked at all the articles, I have done the R's, I have tried to restore it, I have pressed the clickwheel and centre button together and I have toggled the hold switch.

If anyone can help it would be appreciated! (And please save the "take it to apple support" etc... comments for if you can't think of anything else- not being rude but I know this)

Thanks
