Try resetting it by sliding and holding power button for about 15 seconds. Go to http://www.sansa.com/support for more troubleshooting and FAQs. Hope this helps and don't forget to rate the answers.

Try prerssing all the buttons on the Sansa's face at the same time holding it down for a few seconds until the screen shuts down then turn it on again. This should work

If there is a reset button, hold it down for bout a minute, then release it and see what happends

Reset, upgrade firmware:

There may be a pinhole somewhere on it that would reset it. Use a paperclip in the pinhole.

If not mistaken, press and hold the power button for 10 or so seconds and it should cut power to the Sansa. You can then power it back up.
