And if you have integrated graphics, it is likely another portion is sealed off just for the graphics. Open up the start menu and type "resource monitor" and open the program. Go to the Memory tab. It will give a little graphic on how your memory is being utilized. m 0 l ex_bubblehead a b \ Driver a b $ Windows 7 September 21, 2012 4:06:33 AM Maximum address space for a 32-bit OS is 4GB.
