Hi, thanks again for your help.
I have already tried multiple troubleshooting steps (including EA AntiCheat repair, system file checks, reinstalling the game, and updating drivers/BIOS), but the issue still persists.
I have also tested several demanding games, and everything works normally. For example, Battlefield 6 runs stable online for hours, and all other games work without any crashes or restarts.
The BIOS and all system/game-related software are fully updated. The game also worked normally when I first installed it.
The issue is very specific: only FC 26 causes an instant PC restart while playing, with no crash, no freeze, and no BSOD. The system simply restarts immediately.
Because everything else works fine, this seems to be specific to FC 26 or its anti-cheat/system interaction.
I would appreciate any advanced logs or deeper troubleshooting steps for this type of issue.
