I just built a new computer. I have an ASrock Fatal1ty z170 Gaming k4, an i5 6400, and an XFX R9 380(4gb). I haven't installed an operating system yet. When I turn on the system, I can get into the default UEFI(1.40) with the HDMI cable connected to the graphics card. When I try to update the UEFI to L2.23 using instant flash, I no longer get any reading on the display when I press f2 and try to enter the BIOS. However, when I remove the graphics card and switch the HDMI cable to the motherboard using integrated graphics, I can enter the BIOS without any problems. I've tried switching the graphics card to the lower PCIE slot but that didn't change anything. Could it be that I don't have drivers or an operating installed?
Thanks for your time.
**Update** I have now installed windows 10 and all the drivers I need, however, I still cannot successfully enter the new bios with discrete graphics. Instead, when I hit f2 to enter the bios, it displays a black screen and weird white/yellow lines that follow the cursor when I move it. I am at a loss for what to do.
***Update 2*** I thought it might be a problem with the BIOS, considering that it is a beta BIOS version. However, when I tried to flash a newer, non-beta bios version(P2.50), I get the same results.
