Question PC won't boot after turning on secure boot

[pepik_98]

Hello guys,

recently I've swapped to WINDOWS 11 to try it out. Everything was working just fine but after a few days Vanguard from Valorant kept giving me error for not having TPM 2.0 and Secure boot enabled. TPM was enabled but SB was not so I went to BIOS to enable it and after restart nothing was working. The screen is black, USB's don't work only MB RGB lights are on (they even keep running after turning off PC), CPU and SYS fans work but nothing is happening. Sometimes I can't even turn the PC off with button.

I've tried clearing CMOS, disconnecting everything even turning PC on without button connected but nothing has worked and since I can't get to BIOS or WIN I can't think of anything else. GPU is working, HDMI's are fine and displays aswell. Changing RAM's does not help either.

DRAM, CPU and VGA LED's on MB are flashing slowly.

Thank you for every suggestion.

before activating the secure boot everything worked perfectly, this means that the problem is in the motherboard not in the other components

hello looks like this is an issue with these boards i tried the new bios update f14 hoping that would fix it it did not

from what i can see these boards when you turn of csm and have secure boot it hides your drives that are plugged into the mother board, why? that's what i would love to know it seams to me as a bug but i cant go back to older bois version or windows 11 will no longer be supported im going to ask gigabyte about this and see if they can role out a bios fix its nothing wrong with my parts and its the only thing blocking me from installing windows 11, just seems to be a firmware issue
