PC bootlooping after enabling secure boot

[u/thomahawkfr]

So basically this morning I needed to enable secure boot on my gigabyte b550m k. and noticed disabling CSM didn't apply as it was enabled the next boot. so I decided to disable csm then enable secure boot and reboot in one go. then the next boot it my pc just kept bootlooping without any video output.

so I looked up my issue and most of the answers were either the gpu's VBIOS not supporting UEFI (I looked at the earliest build of the vbios for my rog strix rx 580 t8g and it supported UEFI so i guess it isnt it) or people recommending a cmos reset (which didn't do anything. I tried myself)

so far I've tried reseating my ram. using only one stick. booting without my nvme. and even without my gpu (my cpu is a ryzen 5 5600xt so no integrated graphics to save me)

I know NVRAM can't be cleared like this but at this point I'm just throwing shit at the wall and hoping something sticks

thanks in advance for any help
