Question After updating Platform keys PC doesnt start

[kayastein]

I was trying to activate the secure boot to meet the requirements with a video game and apparently it asked me to update the PKs, when I updated them, the computer went black and restarted. Since then when I turn on the computer, the BIOS beeps 5 times and there is no way to enter the bios. It would help me a lot if you could help me as soon as possible.

that means your GPU is not compatible with your UEFI bios, GPU vbios updates usualy fix that
in the meantime swith to integrated GPU (if available) or source another GPU

Agreed. Although it'll be more helpful to know what's the CPU and the motherboard to see if it could even boot with modern GPU, I'm seeing more issue where people tried to use old Xeons with 3060Tis to no avail.
