No POST, when i press the power buttom turns on, power buttom led comes amber for a while then turns off, the pc continue on, fans and psu ON, in the panel no error code, only nerwork and hdd leds on, if I hold down the power buttom its doesnt turn off.
All parts were checked in other machine, video card, memory, pci-x NIC, hard drives, sas controller, and all are ok.
I also tried to power on only with memory, motherboard, cpu, no beep code, no error code in front panel.
Psu checked with the button on it back, it´s ok, solid green when pressed.
I couldnt found in the manual this conbination of power led buttom and front panel. (Power Led off, 1=off,2=off,3=off,4=off) but the pc continues on, with no activity, no video, no beeps, nothing.
I have to discconect the power cable to power off.
Also i tried to clear the bios with no luck, same behavor. (the only difference its that turn on automatically when i connect the power cable)
Someone knows what else can i try? or which is the faulty component, psu or motheboard??
Any ideas??
Thanks
