Defrag error when running defragmetation

[Steve]

When running defragmentation I get Error
message "DfrgFat.exe - Application Error " "The
instruction at "ox7720685" ref memory at "xxxxxxx" the
memory could not be read"

Any suggestions of the cause

Thanks

defragmentation - req's 15% free space to run - and
first run 'chkdsk.exe/checkdisk - and
you might try this routine - ie
1/
a/
run 'chkdsk.exe' - ie
note
chkdsk.exe/checkdisk- scans/repairs errors/flaws ondisk
defrag.exe/defragmentation - reorganizes files on disk
scandisk - no longer supported/incl in windows xp
now
b/
go start/right click - my computer/open/
go right click - local disk/properties/
go tools tab/
go 'error checking section'/click - 'error chk now'/
click on - 'both options' - on dialog box/
ans 'yes' - to sched reboot/
reboot
2/
run 'defrag.exe' - ie
note
use same section/page as in 1/ above ie
go start/right click - my computer/open/
go right click - local disk/properties/
go tools tab/
go 'defragmentation' section/click - 'defragment now'/
3/
then delete temp files - ie
go start/control panel/network and
internetconnections/
go internet options/general tab/
go 'temporary internet files' - section/
go delete files/
go delete cookies/
4/
follow this routine regularly - weekly at least - and
you should maintain clean disk
and
take it fr there
