I have tried multiple times and every way possible to prevent my screen from going into black screen every time I turned on secure boot but nothing seemed to work. I have tried:
- updating bios
- using mobo graphics
I am no tech savvy but I know that every time I turn on secure boot I made sure to have TPM enabled, UEFI and have GPT instead of MBR.
Every time my screen turns black I unplug and plug my cmos battery to force bios to reset which is why I can use my pc but can't play games that requires secure boot.
Any help will do. Here are my specs:

If you unplug the boot drive and other storage drives, does it boot to BIOS when Secure Boot is enabled?
Also, can you list full hardware configuration? >>Posting Guide<<

I don't know how it is today, but Windows definitely didn't like this kind of messing around with turning Secure Boot on and off... Back in the day, if it was installed without Secure Boot enabled, it wouldn't boot up once Secure Boot was turned on. And vice versa. Especially if you're running Windows 10...
The only thing that helped was a complete reinstallation of Windows. Of course, after turning Secure Boot on first...
But as I said, that was back in the day. Today, there might be a way to fix it without reinstalling Windows.

At the same time, though, Secure Boot is enabled by default in the BIOS these days... So I was wondering how it happened that you have it disabled.

Hardware banned? Not saying this is the case but you should eliminate as much as possible. So yeah, try without any drive connected, try with the bare minimum.

Same for you, check the NVIDIA updater first. If that says that an update is available, then that has a chance of helping.
Example screen:

NVIDIA FW update 2.jpg

In the BIOS, try setting Secure Boot to Custom. Then go to Key Management and select "Enroll all Factory Default Keys". Press F10 to save and reboot.
Immediately enter the BIOS again and set it to Standard this time.

What OS are you using (both of you), still Win10?

It's probably something about the Secure Boot keys and/or certificates.

Normally you can check it here in Windows, https://www.windowslatest.com/2026/...-boot-2023-certificate-is-applied-to-your-pc/

But that's not an option if you can't even boot Windows when it's enabled. Basically, what I think could be happening here, that Secure Boot has somehow turned against you on this system, with maybe outdated keys/certificates preventing Windows from booting, as if it was a malicious attempt to bypass it or something. I believe I recently had this on a notebook, where I had to disable Secure Boot to be able to boot again, I don't remember what I did before, probably updated to Windows 11 or something. On there it was a viable workaround to disable it, since there were no games or anything depending on Secure Boot (Win11 works fine with it disabled). But you are between a rock and a hard place if a game absolutely requires it. Blame the cheaters, I guess, but yeah, unfortunate situation, and I don't have a good idea how to solve it, other than trying around with Key Management in the BIOS.
