Hi guys am having a problem with my Asus P5B mobo.
When i start motherboard with no cpu, it starts with no problems.
Now, when i put cpu in socket the motherboard spins coolers for 3 seconds and turn off.
Also when i have cpu in the socket and i DON"T plug in the 1x4 cpu power connector it
also spins coolers for 3 seconds and turn off.

I don't think its mosfet-shim controller cause am getting around 0.5v with out cpu.
There's no short to ground in power mosfets or 1x4 cpu pow. conector.

Also when i measure cpu voltage in that 3 seconds it's showing me around 1.4v.

Can anyone tell me pls where to look regarding this motherboard/

Is anyone having schematic for this board (am having a boardview but no schematic)

Thanks in advanced!
