The PCI controller trains to any device on the bus. It does this to ensure proper communication with the device. If the PCI bus controller is unable to complete this training process then a training error on the device in question will occur. This type of error causes POST to fail.
Normally you would reseat a device that fails to train because most training errors are caused by bad connections. In this case the network interface controller is embedded into the system board, so reseating is not an option. If the controller is failed then the system board will need to be replaced. There are other factors that can cause the NIC to not respond correctly to training, so I would rule those out first before replacing the board.
If the NIC is not receiving enough power then it will not be able to properly initialize. Also, if a device on the PCI bus is disrupting communication then it may not be able to properly communicate. To rule out both of these possibilities you should start disconnecting anything that draws power from the PCI bus such as other PCI cards, and USB devices(Mouse, Keyboard, Thumb Drive, ETC).
If the issue still persists then I would recommend removing all unnecessary components. Anything that draws power or communicates on the PCI bus could cause this issue. This would be taking the system down to minimum to POST. These are the minimal components required for the system to POST:
It doesn't matter ... it is still part of the system's Power On Self Test (POST).

I'm not sure what you mean by this. If this is not what you are talking about, I would suggest clearing the NVRAM using the jumpers on the motherboard.
Aside from that, try removing ALL expansion cards, including the RAID controller and drives. Remove all but a single memory stick in slot 1. Reseat both expansion card (PCIe) risers (must be present for POST, but reseat. And finally, try removing processor 2 (if two are installed), swapping if still experiencing the error.
All of the above are unlikely to help, in my experience, and you will most likely end up replacing the motherboard to fix it.
