Good day Bob.

Depending on which partition is coming up with problems (I am assuming 
/ is the
problem), you may have to use the Rescue Disk to perform the check.

You are unable to repair (safely) file systems while they are mounted, this
causes problems for the / partition.

Put in your FCx CD 1 and boot from it, then use the rescue mode. When it asks
you to mount your system, you want to say no.

It will then take you to a command prompt, at this point in time you 
want to run
fsck.ext3 -y /dev/<drive and partition when root is held>

This should tell fsck to check that partition assuming it is ext3, and answers
yes to all the questions.

Does this help?
