I'm guessing you're on a 32 bit operating system. 4GB is the limit. RAM is pretty cheap nowadays. Upgrading should be easy unless you have a 32 bit OS. I think other people posted about the same issue on this board. Most of them moved to a 64 bit OS like Win 7 or SBS Essentials/Standard. You may want to consider upgrading.
