My computer is running slowly and in system infromation it usually says i have from 20-40mb of physical memory free. I have no extra items running in the tray thing in the bottom right corner just norton antivirus, spy sweeper, sound effect and sometimes msn messenger. I went in to tun msconfig and foud a list of startup progams and i have no extra ones running. I dont have any extra programs running. My total physical memory is 256 Mb. So how do i free some memory up?
