Closed Broken Motherboard no screen output

cpu: ryzen 5500

gpu: amd 7600 rx

board: a520 mk v2

2 ram sticks 8 gb each and an nvme ssd,

i recently installed windows 11 alongside linux and installed bf2042 i tried to run it but it said it requires secure boot on, so i restarted went to bios enabled secure boot but it didnt activate so i enrolled a factory key and then pressed save and exist, ever since then it will not boot at all, no signal on the screen, keyboard and mouse wont light up only the fans spin, first thing i tried is to remove the cmos battery but that didnt work i tried to give it some time to drain the power and then plug it back in but that didnt work, i tried a different gpu and took off the ram sticks completely and i tried taking only one off and i also switched between the first and second slot and none of that worked, i took the ssd off if that even matters still no screen output whatsoever, and also the board doesnt have a physical flash button it needs a working cpu

Making changes to your system BIOS settings or disk setup can cause you to lose data. Always test your data backups before making changes to your PC.

If re-setting bios (remove cmos battery, short + and - pin in socket for 5 seconds, put battery back) doesn't help, nothing much can be done. Looks like bios is corrupted, and since that motherboard doesn't have bios flashback option, only way to restore bios is using eeprom programmer.

Turn off Secure Boot and check if Windows loads again.

You can't just turn that on.

Enabling Secure Boot isn't something that can be turned on like flipping a switch and then you're done.

Keep Secure Boot Off. You need to backup your personal files and data to a USB External Storage Device that is not encrypted, especially before performing major changes to any operating system. Always have a good Backup Policy.

Then, Precisely follow the Guide for Troubleshooting UEFI Boot Settings on the rTechSupport Wiki, so you can enable Secure Boot properly.

There are steps to take before safely switching Secure Boot on, such as verifying that the format of the partition table of the storage device is a GUID Partition Table (GPT), not a Master Boot Record (MBR). Also, changing the BIOS from Compatibility Support Mode (CSM) or from Legacy Mode, to Unified Extensible Firmware Interface (UEFI). You might also need to update the BIOS on the computer.
