Get it seen to. Frozen is not good, trust me. Turn it off, let it sit by itself, switched off, overnight and then, try to turn it on the next day. If that doesn't work, you have a problem. If it is less than a year old, and you have the sales receipt, you can take it to where you bought it, and you will be offered a refund, repair, or replacement (which happened to me when my classic froze - ie died - a few months ago; but it died within warranty, so I was able to get a replacement).
Cheers and good luck
