Game Booster is a great program that allows you to close out all the unnecessary tools that your computer uses in the background. It is also customizable to close out things that you have opened in the background that you feel it is not necessary. Of course you will lose all the good looks on your computer (Temporarily) but get the gameplay and FPS, and better ping you deserve. (Oh yeah, this is free, but you can buy premium or undergo some other way of obtaining it. And I am not suggesting anything O_O)
Step 2: (Download Link) Advanced System Care If you want a little more help then you can get another free iObit service called advance system care it is free and can automatically fix problems on your computer and for registered users there is turbo boost (Not suggesting anything! O_O) So if you feel your computer is bad then go ahead and get this and run it to fix the problems your computer is having. Then if advanced system care tells you that you have viruses (even 1) then search for good anti viruses to attack that son of a btch virus.
