PC wouldnt boot after enabling secure boot windows 11

[NightOwl3010]

sooo i wanted to play valorant but i realised i needa enable secure boot . im pretty sure my nvme is partitioned as gbt. When I enabled secure boot using the custom platform keys , my pc would not boot and instead beeps 5 times. i tried resetting my cmos, taking out the batteries and connecting the two pins with my screwdriver. I knew i should have researched more before enabling secure boot -__---. SSOOO, PLS HELP ME GUYSSS. 

 

my mobo is h370m d3h

cpu is i5 8400

ram 4x4 crucial ballistic sport

hdd : nvme ssd , 2 hdd ( hdd are still mbr as they are quite old and not boot drive so it doesnt matter i guess???)

According to Gigabyte, 5 beeps means there's a CPU error. Do you remember which settings you touched in the BIOS to enable secure boot?

i tried to enable secure boot so i disabled csm. But when i tried to enable it, it said i needed a platform key, so i went to update a custom platform key. restarted my pc and i can finally enable secure boot. After i restarted for the second time, my pc would not boot at all
