Crashing on loading screen to computer shutting off

Hi, after an hour to a few hours of playing poe, my game crashes on loading screen and it instantly turns my computer off. No blue screen of death, no game crashing to desktop, but my computer shuts off. Computer starts up normally after I turn it back, but I don't know if this can have negative long term effects on pc parts.

PC Specs: CPU:
AMD Ryzen 7 7800X3D 8-Core Processor 4.20 GHz
32.0 GB (31.2 GB usable)
4080 Super Nvidia
Windows 10 22H2

CPU and GPU temps hover around 52*C while gaming.

Things I have attempted doing, updating windows and nvidia drivers. Problem still persisted after doing this.

The game never crashed while mid-map, but always in loading screen of entering a map. The game never crashed while I was progressing through campaign.

The problem came back again. I haven't had this issue since patch 3.25.3d Hotfix 2.

Few info: I wasn't on patch 3.25.3d Hotfix 4, so maybe the issue will fix itself after updating.
I'm on nvidia driver 572.47 and I'll try updating to 572.70

for clarity: After a couple hours to a few hours of gaming, my game crashes on loading screen and my computer instantly shuts down. There's no blue screen, no crash reports, and computer starts up normally when I power it on again. I have the latest window 10 update.

edit: I've been playing for a little bit after updating my drivers and PoE client and I haven't experienced the issue again. I think it's still too early to tell, but I'll come back and update the post if I experience it again. Note that when I previously experienced the crash for the first time a couple weeks ago, I also made sure to update my drivers and turned down some settings in the options menu. I still continued to experience the crash until the the 3.25.3d hotfix 2. Some people I've talked to have reported that underclocking their cpu seemed to have alleviated the frequency of crashes.
