8 gig clip wont turn on

i was listening to my clip the other day and during a song it just turned off.When i went to turn it back on it wouldnt.so i just left it.The next day i tried it again and it turned on.It worked perfectly for about 2 days then it did the same thing again.i have left it plugged into the computer over night and it still wont turn on.It doesnt even trun on when i connect it to the computer. Is it dead or does someone know whats wrong with it? 

I tried that and nothing happened.

If it’s still under warranty, contact SanDisk Tech Support about getting a replacement.

thanks, i will try that!

i have tried everything. : ( i think its gone for good.I am going to get one of the new ones i think.thanks for all your help though!

I tried it again today and it works.what is up with that?when it comes back on it stays on the logo for a while then it says low battery even though when it went dead it had half a charge (on both occasions). how do you know if its still under warranty? i got it a little over a year ago.
