My business box, a P133 clone, 64Mb, net card & modem, with a parallel port scanner & no other bells or whistles, runs W98, and a few business apps (WP8, Quicken, Winfax, etc). I also keep System Monitor in the Startup folder, watching available RAM. The RAM slowly decreases, from 31 Mb available after a reboot down to maybe 100Kb, at which time, it runs so slow, I reboot. It will even creep down overnight, when nothing's running (no Taskmon). What's going on?
