Ipod touch Screen wont respond

I just got my ipod touch 2g a couple weeks ago and all of a sudden the ipod froze. So i restarted it and still the ipods frozen i then tryed it again but nothing happened, i then plugged it in my comp but it didnt recognize it as my ipod and said it had to restore, so i did. After it was all said or done it still didnt work. The ipod still works but the touch screen doesnt respond to anything, i cant even unlock it. The volume buttons still work and home and wake still do but the touch screen doesnt. Please can anybody help me?
