Sansa e260 Problem: When I turn unit on, I get black screen and blue menu wheel light.

I am going crazy with my dumb Sansa e260.  When my computer froze, my Sansa e260 went into a blank white screen.  I turned the unit off (holding power 20 seconds).  I cannot get into Recovery Mode or get my computer to recognize the Sansa.

How can I fix this?  Is my unit fried forever?!

Thanks in advance.
