NEW UPDATE ON THIS ISSUE:
I had this happen again and yes this does lock the computer up.
It finally occured to me that maybe the STEREOPLAYERV10.3  system files may be corrupted.
I recopied those and then so far this problem has no come up again but I think this was the issue
and so it may not be the SUPER CPU causing the problem.
