Asus M4A78LT-M LE Black Screen

[passete]

Hello Guys,
I have this mobo Asus M4A78LT-M LE with a wierd issue?
When i turn ON, there is nothing working, no usb, keyboard, mouse, ethernet leds, ... only the fan is running with the Onboard led.
I have tried 3 different bios from asus site, same result?
Tested 4 different rams and also with 3 different PSU's
Wierd things :
I can turn On even with the bios Chip removed
It also turns On without any ram

Any Clues guys ?
Thanks

I think that i found the culprit, some components are missing on the southbridge.
I just don't understand how this is possible, this bga is with it's own heatsink and mostly this mobo come from a 68 years Pappy ....
