It does sound as though it's a motherboard issue. What errors do you see when the system is stripped down? Are the riser errors still there? When you stripped the system did you also clear the error logs from the iDRAC before restarting the system? Did you try draining power completely - remove the mains cable and hold in the power button for 30 seconds?
I receive the following errors when the system is stripped down:
"Critical", "System Boot", "System board voltage is out of range"
"Critical","System Boot","CPU 2 has a thermal trip (over-temperature) event."
As you can see, the riser errors do disappear but a new "voltage is out of range" error appears and the CPU2 thermal trip is still present. The R7910 has been stripped down to only one CPU (always present), one stick of 16GB DDR4 RAM, no riser cards, no mezzanine cards, HDDs, and one PSU. The logs are cleared every time I make a change and try to start the machine, and yes I do drain the power completely prior everytime to nil effect

Definitely sounds like the motherboard then. Can you PM me the service tag? I'll look into your options. Thanks.
