It\'s not an old computer, roughly 2.5 years old.
I starting cleaning out a whole bunch of programs I don\'t use anymore.  I also did a McAfee VirusScan, which I will follow up with a disk defragmentation.  
Can anyone else offer any suggestions for making my computer run better?  I run AdAware every once in a while, I don\'t have to do it dialy anymore ever since I switched to Firefox.  But other than that, I really don\'t know what to do.  I don\'t want to reformat, thats way to extreme for me.
It\'s just that Half-Life 2 comes out in a few days and I want my computer in tiptop condition for its release, any help is appreciated.
