you may find that when your computer is booting up its loading a lot of applications as well. If you go to msconfig, you will see from the startup tab what is actually being started by your computer each time you boot.
My advice is to boot the pc into safe mode and then run defrag, this way any programs like antivirus's and firewalls etc will not be loaded, you will have enough free resorces to run defrag.
Defrag will copy amounts of data into memory and then place it back onto the hard drive.
Once bit of advive before you do run defrag is to run scandisk from dos prompt and also scanreg/fix to make sure that the data you are reorganising is clean from errors.
