BF6 causing full PC hard reboot — tried everything, still not fixed after Season 3 update

Hey everyone,
I have been dealing with a frustrating issue where Battlefield 6 causes my PC to completely hard reboot mid-game with zero warning — no BSOD, no error message, no crash dump. The system just instantly cuts power and restarts. This started happening in 2026 after a game update. The game ran perfectly without any issues from launch day up until then.
This is exclusively a BF6 issue. Every other game I play, including Avatar: Frontiers of Pandora at 4K max settings, runs without any problems whatsoever.

WHAT WINDOWS EVENT VIEWER SHOWS
Kernel-Power Event ID 41 with the following:
- BugcheckCode: 0

This confirms a pure hard power cut with zero software involvement. No minidump files are created because Windows never had a chance to write one.

A NOTE ON THE BIOS
I am aware that a BIOS update has been suggested as a fix by some players. I want to mention that I am currently on BIOS version 1807 which has been rock solid and stable since I built this PC. The game worked perfectly on this BIOS version from launch day right up until this issue started, so it is hard to see how the BIOS would suddenly be the cause.
I am also hesitant to update because newer BIOS versions for the ASUS ROG STRIX X670E-F have known reported issues with DDR5 EXPO stability, specifically with kits like the G.Skill Trident Z5 NEO, which is exactly what I am running. I would rather not risk breaking a stable, working system to fix a problem that started on the game side. That said, if anyone has specific experience updating this board to a newer BIOS version without issues on a similar RAM kit, I would be open to hearing about it.

RESULT
After a full Windows reinstall, fresh BF6 install, everything updated, all settings at minimum at 1080p — the issue still persists and my PC reboots consistently within approximately 12 minutes every time.
I have run out of ideas and am not sure what else to try at this point. If anyone has experienced something similar or found a fix I may have missed, I would really appreciate the help. And if the EA team happens to see this, I hope the detail here is useful — I am happy to provide a DxDiag or any additional logs if that would help with investigation.
Thanks in advance
