Sansa Fuze not working anymore

Question

I turned on my sansa fuze this morning and it stopped working. i tried charging it and it wouldnt even do that. It also wont turn on. What should i do?

I plugged my Sansa Fuze 4GB MP3 player into my computer this morning and it connected. i unplugged and set up the settings like the time and date and then when i plugged it back in it didn't connect or turn on.it said that my usb was malfunctioning, then it did the same this to my laptop. i have no clue if its my mp3 player or if its my computer's USB. please help
