Hi, as the title says i have just installed more ram to get it up to 4gb but my windows xp only see's 2.99gb of it, i know the reasons for it is because some of the hardware is taking up that space. What i want to know is my graphics card using up that space, its a 1gb graphics card, also is their a way to find out what is using that space and i'm posting this here because my question is more to do with memory than my graphics card.
