okay I am building a rig for a guy using the b250 version 1 onda.
he wants windows. and I loaded windows 10 did the up date loaded nvidia drivers booted and I am at black screen.
pissed to say the least. any guess at what to do next.
I tried a few tricks but going nowhere fast here.
I had to reboot after adding the drivers. I had connected a monitor to the on-board HDMI to start with. Have you tried removing the card(s) and seeing if you can boot with the on board video?
okay I had loaded every thing using the onboard video.
booted and got black screen I will try your idea
