Art, You mentioned in your response to my question about memory problems that "NOTE:   BE CAREFUL WHAT YOU CHOSE TO STOP FROM STARTING.   Many of those are system files that need to be running!" Can you give me some tips to know what kinds of things are important? I know systray is important on my 98 machine. What others? What should I definitely keep on my xp machine? Where can I find out such trivia? How do you know it? Thanks, Lisa upstate NY
