Help! My 8gb fuze has locked up on me.

As the title says, my Fuze is on and locked up.  It got past the first splash screen and has stopped on the Sansa logo screen and is now stuck there.  I cannot get it to do anything.  It won’t turn off or go to any other screen.  What do I need to do?  Any help is appreciated.  Thanks.

I figured it out.  I held the power button in the “On” position until it tirned off and now it’s fine.  That’s the first time it’s done that and it freaked me out a little bit.
