Sansa Fuze freezing problem

I have just turned on my Sansa Fuze, and it has just frozen, it doesn’t respond to anything, the blue light is on, and the screen is lit, I have pressed basically every button, plugged it into the computer, heck, I have plugged it into the wall plug, Nothing, unresponsive, and even tried the slide on/off switch, the worse thing is, I can’t even take out the battery. Help.
