My itouch sn't workingg!! whyyy?

The hard drive/processor and/or battery is dying. An iTouch's lifespan is only two or three years. With its cramped size, overheating is quite a problem. One or more capacitors have probably failed. It's just going to become more and more useless. Check how long your warranty lasts, maybe they'll send you a new one and you won't have to buy a new one. If your warranty has expired, just throw it out or take it apart or something.
