Lloyd I hade the exact same problem with mine it was because I accidently pulled it out while it was syncing and that corrupted the hardrive on it. So I went and brought it back to where I had bought it (thankfully it was still under warrenty). They took it from me and told me that they would have to send it to the supplier and it would take about a week, the problem was I was going on holiday in a few days, so I gave it to them anyway. 3 weeks later I came back from my holiday and went to collect it, they gave me the same box i had given them but a brand new ipod inside! So I probably suggest you should bring it back to where you bought it
