your question has confused me, what are you trying to find out, why you dont have full 2 gig usable or why is your computer so slow? If its the slow one i meant to say mabye your using too much space of your harddrive? Even windows 7 slows down when your hard drive starts to get full, it may also be that your running too many applications if it is the case that you think your computers slow and your ram isnt responding.
try defragging and also deleting unessicary items, not alot i can help you with i am not running windows 7 so i cannot trial and error.
But if your questions completely diffrent please explain it more clearly for me
