2GB clip freezing, no files, etc.

Okay so my Sansa Clip (That I bought earlier this year) has been acting wonky the last month.  The first problems were that the screen would often flip over at odd intervals and then lock up.  Okay, no problem, hard boot and let it restart and it was usually fine.  Then I got the synchronization problem that a lot of people have complained about.  I downloaded the firmware and that seemed to solve it.  Now, I had synched all the files from my Clip to WMP11 and used the tag editor to update the songs.  When I tried to sync it again back to the Clip, now the clip has no songs on it, keeps locking up and is currently plugged into my notebook with a blank screen but the blue light behind the control panel is lit up.  Can anyone give me some help?  Thanks!
