I can't seem to solve this issue... It's an i7 11700K (stock settings), 32GB of ram and a Gigabyte 3080. 750W Corsair PSU as well. This ONLY happens when gaming and seems to be random. 2 hours in or 10 hours in.. CPU is liquid cooled.
Event Viewer for critical says "The system has rebooted without cleanly shutting down first."
Seems to only be happening during Lost Ark and Ark at this time.
