Nothing but the blue ring lights up

Ok..idk if this will work but it might...first turn off the sansa...then turn the hold switch on (it should turn red). hold down the record button on the side of the player..then while still holding that hold the power button down...but keep holding them untill a screen shows up saying something about recovory mode..itll say to plug in the usb..u could do that..idk it that will work..it it doesnt instead of plugging in tthe usb in the computer..wait about 15 seconds after the recovory mode screen shows up and then hold down the power button for about 15-20 sec...then itll go all black (including the blue light) press the power button again like u would to turn it on...and everything should be back to normal..hope this helps...:)
