I am trying to boot up my old PIII 700 to fold. When I start it up, the screen jsut stays blank, light doesn't clock green. I can hear the HD booting and everything looks and sounds normal. I have tried different HD's, different video cards, different monitors, different variations of wiring, even the RAM, oh ya and the keyboard. Nothing changes so any ideas as to why this happens? There is a jumper on the mobo to clear the cmos, would that help? I really don't know much about it all. Any help most welcome.
