Hey ya, i just recently changed from vista to xp. same computer i just got the windows xp 32-bit version, I have 2 sticks of RAM in my computer(2GB each)=4GB of RAM, but when I open Control Panel> System, it only says I have 3 gb ;o. If I'm not mistaken 32-bit recognizes up to 4 gb RAM? My vista did. Or maybe I'm wrong xD
