ok sounds like you have a genuine extension conflict... most likely you know what to do there, but first try trashing the File Exchange pref's and the ASLM pref's
i know they do not seem to be related to this problem and they may not be but it will not hurt to try
be sure to reset the File Exchange control panel after restart, uncheck 'PC Disks: Mount at startup' unless you want that feature because it slows the startup a bit
also, trash the invisible file 'Shutdown Check'
