based on what you told me, your graphics card is an intel extreme 2 graphics card, it is shared so it wastes 64 meg memory for the graphics display, you can remove the intel extreme graphics card(ask someone in cnet), and install a Real GRAPHICS CARD, because the intel exttreme graphics card isn't a graphics card but it is supposed to be built in to use your memory asa graphics card. I suggest an nvidia go graphics card.
