Fuze will not charge

I hook up my Fuze with the USB to my computer for it to charge. 

 I had it charging proximately two days ago.

I turned it on today and in 5  minutes it turned off.

I tried plugging it back in my computer so it would charge up but now it’s not doing anything.

Usually when I plug it up to charge the screen will come on or my computer will say  “San Disk has been connected”  but now my computer doesn’t even notice it was plugged in; nor will my mp3 light up. 

Do I need to replace the battery or buy a new USB cable? Thanks for the answers.
