I've been rendering videos on my PC when it froze and restarted unexpectedly. This isn't the first time it's happened, and it's becoming a common issue for me. However, what's unusual is that some of my BIOS settings, including the RAM frequency and, most importantly, Secure Boot, got reset after the restart. I've tried re-enabling Secure Boot following all the necessary steps, like disabling Compatibility Support Module (CSM) and configuring the TPM settings, but my PC refuses to boot with Secure Boot enabled. It starts up perfectly fine when Secure Boot is off. I need to have it enabled since I play Valorant, and I could really use some help figuring this out. Here are my specs: Motherboard - ASRock B450m, Processor - Ryzen 5 3600, OS - Windows 11 Pro. So far, I've tried cleaning keys and installing factory keys in the BIOS, using the Bcdboot command, performing an auto repair with a Windows 11 repair tool, and resetting the CMOS. Any thoughts?

It sounds like your Windows installation is having issues with Secure Boot since it wasn't initially set up that way. You might want to try disabling Secure Boot, then performing a Windows repair or reset, and afterward re-enabling Secure Boot. On the flip side, it’s pretty clear that Valorant’s anti-cheat is making a lot of us focus on security issues more than we might have before! Good luck!
Aside from Secure Boot, check if changing from CSM to UEFI is causing the boot problem. When I tried those settings, I was able to get mine booting, but it’s good to know that—according to your experience—disabling CSM doesn't help much here.

Yeah, that’s right! Disabling CSM alone doesn’t change the boot issue; the PC only fails to boot when Secure Boot is on.
