My Sansa Fuze won't turn on, even when connected to the computer

I bought the sansa fuze 8 GB in Jan. 2011.  It’s new and one other time, it wouldn’t go off.  I was transferring an audio book and the lcd screen was blank but lit up and wouldn’t go off.  It finally went off and then was okay.  That was about 3 wks ago.  Now I was just getting ready to play it.  I powered it up and it went off.  I figured the battery needed to charge so I hooked it to my computer to charge it and it wouldn’t start charging and wouldn’t power up.  I tried to reset it but nothing happened.  Anyone can help
