PC Completely Restarted Mid-Match

Okay so, I may have posted this in the wrong forum before, so let's try it here. Idk how to delete the old one:


What doesn't make sense to me is that my system says Secure Boot is off, but I was able to play the beta for a few matches for a little over an hour. Then mid match of conquest, my PC flat out restarted. Idk if it's because secure boot wasn't on, but that doesn't make sense because it's supposed to give you an error if it's turned off. I double checked and secure boot is definitely off. I have TPM 2.0 and ready for use, my partition is GPT like it's supposed to, yet I didn't encounter a warning and was able to play for a bit before the hard restart. Could the crash be related to secure boot being off? I have a 13700kf cpu, a 4080, and Z790-C mobo. Game was running just fine on High Settings at a stable 90fps. I'm a little anxious about going in and messing with BIOS settings since I've been reading that some users have been experiencing some major issues like causing their PC to not boot up properly or "bricking" it as some have said. Any help is greatly appreciated to try and narrow down what the cause could be.
