Hello,
I have a strange issue with the GA-Z87X-UD3H and my Sapphire HD 6950 video card.
With the video card installed in either the PCIEx16 or PCIEx8 slot, the BIOS logo screen will not display and will go straight to booting Windows. So I couldn't adjust the BIOS settings at all.
If the GPU is out of the motherboard, I can see the BIOS logo and go into the UEFI BIOS setup.
The strange thing is that Windows detects the video OK but no video signal is sent through the motherboard to the GPU during POST.
I have updated the BIOS to F5 which is the latest stable one from the Gigabyte UK site. This BIOS still displays this strange behaviour.
I've spent hours playing around with BIOS settings to get it working but no luck.
Is there in incompatibility with my GPU? Is my only solution is to get a new video card?
Any help would be greatly appreciated.
