Hi David,
if you Google for the mainboard Asus M3A78-EMH HDMI you will see in product listings that's from 2008.

I upgraded my Windows 7 Pro license to Windows 10 Pro using 1511.
Nevertheless Windows 10 Pro is running well on this HW with 1611, 1607 and 1703.
I don't know what has been changed in 1709 so that I get problems now.
I could do a new installation on a new disk.
Any more Ideas?
And for the 2nd machine from my friend he has more or less the same machine with the difference that it has a Nvidia Quadro (PCIe ?) instead of Onboard Intel and 3 GB instead of 2 GB RAM and no problems while upgrading to 1709.
Thank you in advance.
