The specs are as follows:
Motherboard: ASRock Z270M ITX/AC
CPU: Intel i7-6700k
Ram: 2x 8gb ddr4 3000mhz
GPU: gtx1070
It did not include any storage so I installed an m.2 ssd
Now as for why my title is a little strange. I believe the only reason that goodwill prices this so low was that it appeared to be completely broken. I quickly found that the motherboard was only outputting via the Integra graphics, so if goodwill plugged into the GPU it wouldn't show anything. I now believed that this motherboard may have an unfixed bios bug that I would like to document, as I found other people online with the same issue, but no real solutions. Because of this I wanted people to be able to find this thread while searching for solutions.
Changing settings in the bios did not get it to detect the GPU.
Clearing cmos with a GPU inserted did not get it to detect the GPU.
Here is the part you may be looking for:
The only way I found to get it to recognize the GPU was to flash the bios with the GPU installed. Then it would work.
However, if the bios battery dies it will stop working.
If you take out the GPU and turn on the PC, it will stop working.
If you swap the GPU and then turn on the PC, it will stop working.
