OK, here's the situation. I'm installing a used Compaq MB(PIII 733Mhz) into a friends old Toshiba PC. The power supply is a 200W 20 pin and the MB is a 24 pin. No problem, I get the 20 pin to 24 pin connector, connect the power switch wire to the MB, power to the floppy and HD. Hit the switch...no light, no fan, no beep, no nothing. I took apart the Power supply and checked the fuse, it's OK. Does anyone have a suggestion for me? Please help. Thanks
