Do a single user boot (hold command S on start-up) at the system prompt enter "fsck -f" this will force a file system clean up. you may have to repeat till you get a " The volume appears to be OK" message then type "reboot" to restart your machine. If this doesn't work try moving all of the files out of your user>your account>preferences folder into a another folder and reboot. then begin the laborious process of of swapping in an old preference file one at time until you find the offender.
