Maybe you should go in and delete some of the programs you're no longer using as well as clearing your cookies and cache. Some time going through files that you've saved and no longer use or no longer need will clear up space. Also check your processor maybe you need a new one or a just a whole new computer. Example, it's like having a brand new mustang (that you wanna race) but an old engine in it. you wont get the full power because the engine is old and outdated.
Hope that helped.
