defrag disk will not start,please help

Try this:

Start>>Run

In Run enter the below text one line at a time and click OK after each entry:

regsvr32 dfrgsnap.dll

regsvr32 dfrgui.dll


If defrag still does nothing, open Run again and type "inf" without the quotes and click OK.

In there you will find a file called dfrg.inf right click this file, and select Install

Try using DEFRAGLLER by Piriform.com instead.
It acts more efficient than the built in defragmenter in windows XP.
