My computer has recently developed a strange habit. In certain games, specifically The Long Dark, Chrimson Desert, and Cashgrab: Refunded, after a random amount of playtime ranging from minutes to at max an hour, my computer will just shut off. Not blue screen, but instead just turns itself off including fans and rgbs. Sometimes this is accompanied by a green flash across my monitors. My drivers are up to date, I just upgraded my power supply because I thought that was the issue but it fixed nothing. Windows event viewer provides me with the following event error id, but I can't find a lot about it online.

Event ID 56

PCI00000001004CE00000

Motherboard: ASUS Tuf B650

CPU: AMD Ryzen 7 7700

GPU: AMD Radeon RX 7800 XT

Ram: 2x G.Skill 16gb DDR5-6000

Does anyone have any experience with this or something similar? Are there any remedies I can do myself? I'm starting to suspect it might be the motherboard.
