Hi, I have a gaming PC running a AS Rock 970 Pro3 motherboard. This has stopped working - when the PC is powered up, the LEDs flash once for half a second and the PSU switches off therafter.
I have replaced the PSU with a new unit, and the result is the same.
During faultfinding, the tripping disappears when the 8 pin ATX 12V Connector on the motherboard is not plugged in. This connector apparently supplies more power to the CPU according to the manual.
We have also unplugged the cooling fans on the ECU cooler (Cooler Master) with no change - the fans do run if the PC powers up without the 8 pin connector plugged in.
A concern that I have is that we can damage the motherboard if we switch on and off while testing with this plug not plugged in. We have not yet removed and re-seated the CPU, and not sure if this would help?
Any suggestions for faultfinding welcomed.
