PC boots to windows 10 but can't boot to bios

[Ekansobi]

Spec list:

Z97 PRO-GAMER

i7-4790k

4x4 GB RAM

GTX 1080

GTX 660ti

 

 

Details:

The computer boots fine to Windows 10 but won't show splash screen or open bios (after clicking f2 or del). If I use those inputs to try to open the bios the computer just black screens (no signal on all monitors) until I restart it. Outside that the computer runs just fine after it boots to Windows.

 

What I've tried:

I've updated the display port drivers, I've swapped around the HDMI cables and display port cables around and plugged them in different combinations on the two different GPUs and also motherboard(iGPU).

Pre built, or home made?

Also, are you running a backlit keyboard with multiple USB plugs?

It's just probably trying to show up on the wrong connector. You could temporarily remove both the GTX-cards, then it'd probably show up on the iGPU's output.

Hold the shift key, go to start, power, restart. Release the shit key and you will be prompted to a menu, select restart in bios

Home made, yes I'm using a backlit keyboard with multiple USB plugs. I'll also remove my gpus and try to boot jt up

I had to remove everything and finally got to see the bios after the only GPU being the integrated one. ty
