Clean out your damn computers. Use spybot, it's free, to get rid of all the spyware and addware. Then, clean out your registry with the cleaner of your choice. Next, make sure your hard drive is defragged often if you are constantly installing/uninstalling software. Now, when you say your computer is slowing down when running video or games, then it could be as simple as you needing a newer card. You need to always post your system specs when you ask an IT question, or you will get no positive answers.
