I have a huge RENDER problem! HELP!

When i rendered an animation with this model some strange lines appeared on it and it looked like noise. Does anyone know how to fix it? I can send the video showing the strange noise in action in HQ and the .blend file!

Heres the video where you can see that the blue colour of the torso has moving noise - http://tinypic.com/player.php?v=34y6uc4&s=6
