I have risers but tried directly into mobo as well. In bios still nothing. I've checked connectors and have tried with 2 different psu's. Could it be a problem with my new Celeron cpu? That is only part I haven't replaced. Lol! I think I'm missing something windows related but it was still not detecting bios before I installed windows. also the ddr4 4gb ballistic hasn't been changed. sorry if I'm using wrong terminology I'm just excited to be involved.
I am suspecting possible improper installation of GPU here, check your Bios setting, and Board Explorer from there you can check if there is a GPU installed and detected, otherwise check your GPU installation. basically, if its not seen in the BIOS it wont get to seen also in windows.
