PC crash

I've been unable to play in the past 24 hours. After launching the game, after the gear grinds and the ember/fire shows up, PC just reboots. Found similar posts about going into the affinity via task manager and unselecting CPU 0 and 1, took me about 15 boots to get that far, but it doesn't fix the problem.

I've also tried reinstalling the game (was doubtful and rightfully so), same issue. What is there left to fix? Playing since hour 1 of launch and only had this type of crash in the past 24 hours.

PC specs for reference

win 11
i9-12900k
3080 Ti
samsung 1TB SSD

Forgot to add this is only POE2. every other game doesn't crash or reboot PC, including POE1.
