You do neet memory for the operating system and other running processes!

Win2K doesn't release 'used' memory in some cases. Not sure if CS2 is as
much a contributing factor, but ... the memory 'pool' shrinks.

You might consider grabbing a copy of XP-Pro before they're gone and you
have to deal with hassle laVista.
