Oops PC not posting.

I have a home-built PC, with a b550m gigabyte motherboard. So, I tried to get my pc set up for Windows 11. As I'm sure many people are aware that requires secure boot enabled. Long story short, I didn't do enough research, disabled CSM, and now my PC won't post. I have tried removing the CMOS battery and shorting the CMOS pins to no avail. I have also tried using Q-flash to update my BIOS, but that doesn't seem to be working either. Any suggestions? Or is my board bricked?

Clearing CMOS will revert the board to the default UEFI boot.

 

Take it apart, put it back together with the minimum components.  CPU, cooler, 1 stick of memory, video card only if you have no onboard video/APU.

I've tried that. The CMOS clear doesn't seem to have any effect. I've also tried rebuilding it barebones, but no effect either unfortunately.

If you are using a dedicated GPU as opposed of the integrated iGPU on your processor it won't work. This happens in many motherboards after disabling CSM, but take the CMOS battery should work.

Yeah, that's what I figured, but no luck. Thanks though.

Which connection are you using in the GPU? Is it DP? You might try then HDMI just in case as this has worked for me in some cases or if there was the case where you have an old GPU with a VGA or analog connection you could try that as well.
