ok looks like that didnt quite work the way I wanted it too. I tried this and the computer will just not boot now from the dc-dc power supply. I know its putting out voltage in the pins i tested it as positive. I connected everything but the "fan off" pin. I tried attaching that to ground, ps ok, and 3.3 . I know power is getting to the compaq because I can hear the thing clicking away somewhere (not the hard drive or anywhere else... someplace on the mobo. anyone have any ideas on what to do??
