My iPod classic 80GB crashes when either i push my headphones down too far and (the most annoying) plugging in the charger. It still charges my iPod but it means I cannot sync it with my computer. It is driving me mad. Is there any way I can fix this? Also it doesn't mind having the power connecter in but as long as there is no power in it. I.e. i can put it in and it will work but when i plug it into my computer it crashes. Thanks.
