After resetting PRAM, removing multiple 3rd party S/W and many other S/W fixes, I finally found a solution to this one: the Bluetooth module (H/W) was dead...bought and installed a new one...everything's wonderful.
Yours may be another H/W failure (HD!)... try accessing all in the sys pref.

This sounds correct. What you want to do is immediately launch ACTIVITY MONITOR and see if SystemUIServer is RED. If so, it means that it's hung. I've had problems with this too (and it also took luanchd down with it). IF you ForceQuit SystemUIServer from Activity Monitor it should restart itself.
What you also may want to do, is open Console and go into the system.log and see if this error pops up anywhere:
IOATAController. IF you see this mentioned, it oculd be a faulty hard drive. I just took one of my Macs into the Genius Bar yesterday, and the Genius was like "you're probably 100% right. Let's just swap the drive."
