running defrag on 98SE, it just keeps restarting over and over (as does scandisk) after about 10 sec. have rebooted etc still won't work. only TSR ( ctrl-atl-del and look in box) are: explorer, systray, fwlink. anyone know what is going on? I found out cos I left it to defrag over the weekend ( only 2Gb disk) and it hadn't done anything when I got back today. Tried scandisk to see if it could fix it, no joy.
