The first thing you should be aware of here is that 32bit systems will not recognize more than 3GB of system ram which you already have. The 4GB limit you may be thinking of includes graphics cards and the like - you could add a 1GB graphics card and still be okay (theoretically) but adding ram modules will accomplish nothing since anything over 3GB will neither be recognized nor used by the system.
