[SOLVED] Computer won't boot up after I updated system keys

[Vilqx]

I have a Gigabyte B450m DS3H. I updated my system keys to the default one, so I could enable secure boot. Now, my computer won't boot. I press the power button, then the light comes on, fan spins, but nothing else. Anyone got help?

I updated my system keys to the default one, so I could enable secure boot. Now, my computer won't boot.

If enabling secure boot causes problems, then disable it.

I wanted to use the Windows 11 Preview version, which requireds UEFI Secure Boot to be on. And in my BIOS, in order to turn on secured boot, I didn't have the right keys. So I went into my key manager, and I pressed update and got the default platform keys. I saved and exited the BIOS, and now the computer wont turn on, so I can access my BIOS to revert the changes.

Reset BIOS settings with onboard jumper.
Read manual of your motherboard for instructions, how to use clear cmos jumper.

Okay. I seems like a lot of other people with Gigabyte mobos are having this same issue. I had also changed some other settings in BIOS to UEFI Only, but I don't think that is the issue because the computer was able to boot after doing that.

I removed my GPU, used my jumper to clear, and then when I put my GPU back into it's slot and plugged the HDMI in, the computer booted again. Thanks for your help!

Did you try to clear cmos without unblug the GPU?

Did you really fix it?

I reset cmos multiple times by jumper and also tried removing battery for 5-10 minutes but it still only gives black screen. I also tried with different gpu. Any tips?
