My mp3 player is frozen. (by 5 users)

My mp3 player is frozen. Normally when your supposed to turn it on it should say "BenQ" Then it goes to the song, but when I turned it on a few days ago it was stuck on the very beggining. It said "BenQ" and was stuck there, I mean it was frozen there it wouldn't say anything else. Also when you plug it in the computer it doesn't show. I've already checked the USB ports there isn't anything wrong with them. I opened the mp3 player to try to fix it, but there wasnt much I could do. Please try to reply as soon as possible.
