I've been experiencing some random shutdowns with my gaming PC setup, which includes a Ryzen 9 5950X, 64GB of RAM, a 3090 GPU, and an Asus 1200W power supply. It seems to happen mainly when I try to boot up PUBG. The computer shuts down completely without showing a Blue Screen of Death (BSOD) and doesn't restart on its own; I have to manually press the power button to turn it back on. Strangely, it never remembers the BIOS settings after turning off.
I even tried moving the PC to a different room, and when I boot it up there, it works perfectly fine without needing to go into the BIOS. However, the next morning when I return it to my room, I'm back to the same weird issues. I'm really confused about what's causing this problem!

That's an interesting issue, especially since it works fine in another room. Have you checked if there's any interference in your original setup? Double-check if there are other devices or appliances that might be affecting the power delivery when it’s in that room. Sometimes, poor power quality can cause weird shutdowns.
It sounds like there might be an issue with your power supply (PSU). Make sure all power connections are secure, especially the one to your GPU. Another possibility is that your motherboard could be faulty since it’s losing BIOS settings. Try changing the CMOS battery and see if that helps. Updating the BIOS to the latest version could also make a difference. If you have access to another power supply, testing with that would be ideal, and checking another GPU could also help rule out hardware issues.
