[SOLVED] [SOLVED] Secure boot = no display... (My bad)

[rabi0ne]

Hello everyone!
Gigabyte b450m ds3h
R5 5600x
4x8gb ddr4 2666mhz
Rx6600xt
PNY 500gb nvme

My dumb mind tried to enable secure boot on this mobo to play faceit (for cs2).

I didn't google before, thinking it is as simple as enabling most things in BIOS (been playing with PCs since x486 yet still dumb af)

fTPM was ON.
CSM was ON.
I enabled personal key (if i'm not mistaken), then enabled Secure Boot and restarted.
Didn't get a signal after that... Ofc clearing CMOS didn't work with both methods.
Kb and mouse don't light up.

Is there a solution except RMA ? Or my mobo is bricked?

Help plz!

Secure boot works with UEFI, Reset CMOS by removing battery.

This is Gigabyte board so you are screwed. If you have access to CPU with integrated graphics it would be worth a shot to install it see if it helps, but otherwise if you can RMA the board just do it.

 

[rabi0ne]

It was already on UEFI... Removing the battery for more than 10min AND shorting CLR CMOS jumper didn't do nothing...
As @DRagor said, i'll have to try an APU... The problem is that the kb and mouse don't light and the PC can't even be shut down unless i push the on off button for 5sec...

 

[DRagor]

The problem is that the kb and mouse don't light

Quite likely bricked BIOS causing this. Common issue on old Gigabyte boards. The newer ones have Secure boot enabled on default (which comes with its own problems btw but at least you don't risk bricking board).

Damn :/ So i have to change the mobo then...
I guess the bios chip can be changed by soldering?
Thank's for your replies man. Despite it being a lost cause...

It should be possible to just re-program BIOS chip without having to resort to soldering. Unless it is bricked beyond repair that is. It is a 15 mins work for someone with right equipment.

You THE BEST !

Using cpu with integrated graphics is the correct way for solving this.
The board does not get bricked by enabling secure boot.

Ok i'll try it!!

replacing cpu should trigger ftmp/secureboot reset, throw in some random am4 low end apu which is still supported by your bios (see mainboard cpu support page), then return it once youre finished with setting up secureboot on gigabyte mobo

YOU SAVED MY LIFE DEAR BROTHER!

I found a 2400G at a friends computer shop.
It asked to reset fTPM.
Did it.
Found in the BIOS that CSM was disabled.
Continued steps to activate Secure Boot (standard, reset etc...) and put back my 5600X. It asked me again to reset fTPM and it works now!!

Thank you for everyone involved!!
