My first guess would be that because the RAM is shared between the graphics and the rest of the system (Onboard Shared Graphics) and the fact that XP Pro has a lot of extra processes installed when compared to Home edition, the RAM is being eaten more then it was, this is only IF you are actually using the onboard graphics, if you have a card installed then this will not be the problem.

When i mentioned Pagefile above, i actually mean Virtual Memory, here is a better explanation than i can give: http://aumha.org/win5/a/xpvm.php i was wondering if it is controlled by Windows, or if it has been set by you.
