I am running windows ME on a Pentium III 700 mhz with 192 mb ram. About a half hour after I start up my computer it slows down considerably. At this point the amount of physical ram avaiable is less than 1 mb. It seems as if I have a memory leak somewhere and I don't know how to find it or what to do about it. Also when I run defrag, I have to close down almost everything running in order for it to work. Please help.
