Question I changed some BIOS settings. But now I have no display. How do I fix this?

[bbxpro]

Hey guys I was changing some settings in my brothers BIOS to get Secure Boot running, and I must've changed a weird setting (I think it was something like System PK keys or whatever?)

However, after doing that, it no longer shows a display.

I've tried:

Using HDMI cable,

Using DP cable,

Different monitor,

Different GPU,

Different RAM,

Reset CMOS battery,

Jump CMOS battery,

Replace CMOS battery,

Notes:
All fans spin, all LEDs are on, just "No Display" on monitor.

I suspect that either the motherboard or CPU is cooked, but hopefully the motherboard because that's cheaper to fix. Can someone help me please?

full system spec?

Remove discrete graphics card from system.
Use integrated graphics instead (cpu needs to have iGPU for this).
Boot into BIOS and disable secure boot.

If your cpu has no iGPU, then you're out of luck. You'll have to obtain cpu version with iGPU in it.

Just curious, if the whole purpose of getting an iGPU is to enter the BIOS, why wouldn't resetting the CMOS battery fix my problem too? Wouldn't that reset all settings and disable Secure Boot?

This is a common problem on Gigabyte boards, when enabling secure boot with discrete graphics disables video output completely.
One way of resolving is by using integrated graphics.

Another way, that could work - using BIOS update, if particular board supports BIOS update without cpu installed.
But this is more risky, because borked BIOS update will brick motherboard and then there's no easy way for reviving it.

BTW - why haven't you listed your pc specs yet?

As requested earlier, a complete listing of your installed components (make and model of ALL) would go a long way toward others being able to give advice on how to resolve you problem.
