PC won't boot after enabling Secure Boot?

[Loli Pits]

I installed Valorant and it told me to enable secure boot in order to play the game... After I did my pc wont boot anymore...

 

Things I tried:

-removing cmos battery overnight

-unplugged all unnecessary things  (keyboard, mouse, drives etc.)

-tried every combination of ram placement

 

I cant boot to bios... Gpu and ram leds turn on... Gpu fans turns on and off endlessly on a loop...

 

Monitor is blank with an orange led... Its usually blue...

 

I sent the motherboard ram and cpu back to the shop i bought them since theyre still under warranty... They cleared them and it booted to bios...

 

Only suspect left is the gpu... Is it possible for a gpu to not be read by the system just by tinkering with the bios? Isn't removing the cmos battery supposed to fix it since it resets everything?

 

I am yet to try the gpu on anither system since I dont have friends (i mean... look at my name)

 

Assuming the gpu works just fine and is just not read by the motherboard... What do I do to fix it? 

 

Since it booted in the shop im guessing some gpus works on the motherboard and something about mine is the issue...

 

Specs:

Ryzen 5 5600X

Sapphire RX 580 8gb

16gb 3600mhz ddr4

Gigabyte a520m ds3h

You said the shop could boot into BIOS but you still can't ? Have you tried all the ports on your GPU ?

Can you boot into the BIOS when there is no HDD/SSD/NVME connected.

 

Because you would need to re-install Windows if you change to secure boot.

If you have installed the non-secureboot version of the Windows bootmanager.
