Cannot pwr up IBM pc without unplugging pwr cord
I am working on a IBM pc, machine type 6589-12u, wins 98se. I about had it all going when I tried to pwr the machine up it failed to do so. When I unplugged the pwr cord from the back of the machine, I noticed the fans kicked on for just a micro second. I can get the machine to pwr back up only by plugging/unplugging the pwr cord numerous times until something hits just right and the machine will pwr up. It this a pwr supply problem, switch problem, or something to do with the IBM soft pwr on/off. I have changed pwr cords. Thanks for your help.
