Menu + center button for a few seconds...or on iPod Touch: Sleep button + home button for a few seconds......couldn't you have google'd this?
I probably should have mentioned that the menu+center didn't work.
There is some sort of switch on top (I think it's called "Hold," haven't used an iPod for a while), hold it until the iPod works.
The word "froze" is offensive to me...By FREEZEEdit: Lol
