Dell Inspiron Problem

I have a dell Insprion 4000 notebook with suse 7.3 running on it. Everthing works great excpet every time I shut down or reboot it say's file system was not cleanly unmounted and then runs file check. It seems to shut properly and I don't get any error messages when shuting down. Any Ideas? Thanks --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).
