Can't run defrag because Chkdsk /f is scheduled. Can't runchkdsk /f because it is in use by another program. How do I find the program so I can defrag my local disk?

My Computer has begun to slow and fragment. I tried to run Degrag form the Assessories, Ssytem Tool, Defragment Program.

Error message say can't do because Chekdsk is receduled to run. Run Chkdsk /f.

Can'trun Chekdsk /f by using command prompt because it is in use by another program.

I ran checkdsk /f at Start Up but still cann't run Degragment or Annalize.

I tried to run it from the Control Panel Task also with the same results.

How can I defragment my local disk?
