Well, I don't think that software is causing any problem.. But still give a try..
You can find out defragmentation function >startmenu>Accessories>Syste tools>Disk Deframentor
That's where it is available in windows 7.. In xp also there should be something like this, or try directly searching "defragment" in search of start menu.
