After enabling Secure Boot for my system, I ran into a major issue. I turned off CSM and enabled Secure Boot in the BIOS. Then, I followed the prompts to install PK KEYS. Once I saved my changes and attempted to restart my PC, it just entered a POST loop. Now, I can't even access the BIOS. Is there any way to fix this situation, or am I out of luck?

Don't sweat it too much! Just remember to keep your patience for the next stages; you’ll definitely need it. Hopefully, you can resolve the boot loop soon so you can enjoy your games without these technical hiccups!
It sounds like your system might have been in legacy BIOS mode before. What I recommend is first turning off Secure Boot and turning CSM back on. Then, if you can boot into Windows, check out a guide for converting from MBR to GPT (it can be a bit tricky!). After you've done that, you should be able to disable CSM and enable Secure Boot again.

Thanks for the encouragement! Just trying to get this rusty box running smoothly.
