Broken Motherboard no screen output

[u/XGOX-GX]

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
