What Can I Do To Make My Computer Faster???

There are several programs I put on every new system. I put clam win anit-virus, a freeware program found here: http://www.clamwin.com/. I also put Real Alternative and Quicktime Alternative, becuase RealPlayer and Quicktime take up so many resources. They can be found here http://www.free-codecs.com/download/Real_alternative.htm and here http://www.free-codecs.com/download/quicktime_alternative.htm respectively.
