:( New computer as of last year. No fans are running on anything, have about 4 or 5 inside. The led is on the motherboard not near the powersupply. Not sure about that 4pin thing. I don't think the front power switch is off because I'm not even getting the green led light in the front. Seems the only thing working is a mysterious little red light way down low in the tower. sigh I'll come back on with more details of the components in case that'll help. I just wish there was a breaker switch that I could just flip. I'll be back. Thanks guys.
