[SOLVED] Graphics card not working after disabling CSM support and enabling custom secure boot

[kanirou1x]

I recently upgraded to Windows 11 and a few days after the update I installed Valorant and every time I booted the game It would tell me that I needed to enable TPM 2.0 and Secure Boot in my systems BIOS. I went into BIOS to enable those settings and I did that but it didn't fix the issue. I read somewhere that disabling CSM support would fix it so i tried and now my graphics card isn't displaying to my monitor.

I tried resetting CMOS two different ways, Using different PCIe for my GPU. Reseating and moving around RAM sticks, I've removed and reinstalled every connector and part on my motherboard except for my CPU. Im wondering if booting BIOS from a flash drive would help but I doubt it since I wouldn't be able to see it anyway. Im pretty sure the graphics card still works since the fans on it are spinning. I read in this forum that if you have an integrated graphics on your CPU then you can use that but I dont have integrated graphics on my CPU so i dont know what to do. How do I disable CSM support without a GPU?

Edit:
PC Specs are as followss:
MOBO: Gygabyte B550M Gaming X V2
CPU: Ryzen 5 5600x
RAM: Teamgroup T-Create 3200mhz 16gb ddr4
GPU: ZOTAC GAMING RTX 3060 Twin Edge
SSD: 250gb WD Blue NVME
PSU: EVGA BQ Bronze 80+ 850w

So, to install Windows 11 in the first place you are supposed to already have disabled CSM, enabled Secure boot, and enabled whatever is required for that particular platform to enable Trusted platform module support and it is different for each camp, and occasionally even for each generation of platform.

I would attach your license to a MS account if you haven't already, and do a clean install of Windows 11. There are myriad reasons for doing this but primarily it's because Windows is incredibly bad, and so are most BIOS, at forgetting what was installed BEFORE and ONLY worrying about what is installed NOW.

So, try taking the card COMPLETELY out of the system.

Then do a hard reset and then reinstall the card, and power on, and hopefully be back into BIOS access by then.

BIOS Hard Reset procedure

Power off the unit, switch the PSU off and unplug the PSU cord from either the wall or the power supply.

Remove the motherboard CMOS battery for about three to five minutes. In some cases it may be necessary to remove the graphics card to access the CMOS battery.

During that five minutes while the CMOS battery is out of the motherboard, press the power button on the case, continuously, for 15-30 seconds, in order to deplete any residual charge that might be present in the CMOS circuit. After the five minutes is up, reinstall the CMOS battery making sure to insert it with the correct side up just as it came out.

If you had to remove the graphics card you can now reinstall it, but remember to reconnect your power cables if there were any attached to it as well as your display cable.

Now, plug the power supply cable back in, switch the PSU back on and power up the system. It should display the POST screen and the options to enter CMOS/BIOS setup. Enter the bios setup program and reconfigure the boot settings for either the Windows boot manager or for legacy systems, the drive your OS is installed on if necessary.

Save settings and exit. If the system will POST and boot then you can move forward from there including going back into the bios and configuring any other custom settings you may need to configure such as Memory XMP, A-XMP or D.O.C.P profile settings, custom fan profile settings or other specific settings you may have previously had configured that were wiped out by resetting the CMOS.

In some cases it may be necessary when you go into the BIOS after a reset, to load the Optimal default or Default values and then save settings, to actually get the hardware tables to reset in the boot manager.

It is probably also worth mentioning that for anything that might require an attempt to DO a hard reset in the first place, IF the problem is related to a lack of video signal, it is a GOOD IDEA to try a different type of display as many systems will not work properly for some reason with displayport configurations. It is worth trying HDMI if you are having no display or lack of visual ability to enter the BIOS, or no signal messages.

Trying a different monitor as well, if possible, is also a good idea if there is a lack of display. It happens.

it seems to me updates aren't enforcing the tpm and secure boot rules Darkbreeze.
Clean installs probably need all that on but updates? seems its getting a little lenient.
if PC can turn them on, that seems to be all they care about.

Valorant meanwhile is a pain.

if secure boot means its not booting, he probably also has drives as MBR still.
Turning CSM off and having mbr drives isn't going to work.

I have seen a number of people with same story.
Vanguard thinks it owns the pc - Vanguard being Valorants anti cheat.

1. User updates to 11
2. Valorant demands user turn off CSM and turn on Secure boot
3. user does
4. PC shows black screen on startup

Somewhere in process user should be shown what to do properly. Its currently a hole in the instructions.

Answer is normally to flash bios with newest version or if its a Dual bios model, boot off the backup bios and then once it boots and everything again, run https://it-infrastructure.solutions/how-to-switch-from-legacy-to-uefi-boot-mode-mbr2gpt-convertion/ and do it in the right order

its probably not the GPU playing up, its probably the black screen after enforcing secure bug thing Gigabyte motherboards do.

Note: If you are just enabling it to install Windows 11, its is not necessary. Windows 11 just needs PC to be able to run Secure boot, it doesn't enforce it. Valorant is a different story credit to COLGeek for instructions Steps to enable (all AMD-based Gigabyte mobos) Secure Boot. Make sure...

I've done all of that except for reinstalling my OS altogether which i'd rather not do but the rest of that is what I've been hearing from different articles and youtube videos. None of it has worked though, but thanks for the suggestion

Just tried this and it worked
The problem was that I didn't have a small capacity USB 2.0, all i have are 64gb or more USB 3.0 flash drives and thats what I used when i tried flashing bios the first time (a few days ago) but that didn't work so I went out just now and bought a 16gb 2.0 and it worked. Thank you so much for that suggestion because I woudn't have bought a small capacity 2.0 if I hadnt read that article. You saved me so much time and money you have no idea. Was almost just gonna buy a new mobo
