I am rebuilding an old PC. When trying to boot the first time the motherboard onboard power led lights up and nothing else happens.
The power supply fan doesn't start
The CPU fan doesn't start
The chassi fan doesn't start
No reaction from the screen
No reaction from the mouse
No reaction from the keyvoard
My setup is:
Motherboard: ASUS M4A785TD-V EVO, Socket-AM3
CPU: AMD Phenom II X4 945
Memory: 2 matched pairs Corsair XMS 4096MB DDR3 PC3-10666 1333MHz (9-9-9-24) (2x2048MB) (TW3X4G1333C9)
Power: 500W Seasonic nätdel, ATX, EPS12V, BTX *
Disk: Western Digital Caviar Green 1TB (IntelliPower / 64MB Cache / SATA II / NCQ)
I have done the following checks:
Tested the power supply, measuring all voltages. All values OK.
Took the mb out of PC, put it on antistatic, added power, shorted powe switch terminals to eliminate faulty frontside powerswitch.
Cleared CMOS
Turned onboard battery upside down (changing polarity, recommended by Asus) then returning to correct polarity
Removed all connections to disks and dvd
Still no effect. Only the onboard power lights lights up.
I have been building systems as a hobby for over 20 years now, but never encountered a new faulty mb.
Do I have one now?
