Why wont my 5th generation iPod respond?

So i was listening to my ipod 5th generation, it was working fine, no battery issues, ive never dropped it or split anything on it its pristine basically. Then it suddenly stopped playback, I could here the click wheel but the screen was black/off. It now wont turn on and I cant hear the click wheel. Ive tried plugging it into my windows laptop, its not recognised in my computer or itunes and isn't charging but when I plug/unplug it the comp makes the 'budump' noise that windows does. Doesn't sound like its battery related from reading other reports as its not got steadily worse just suddenly stopped. Would it turn on when attached to the computer if it was a battery fault? Anyone got any ideas what it could be.

Cheers!!!!!!!!!
