What happens: Random PC crashes. No blue screen, or crash screen. The PC literally turns itself off. Happened first on the TGV line when approaching the voltage changeover. I think it happedend 3 times, so it was kind of reproduceable. Then it happened then when I was just scrolling in the main menu to select the loco. As I intended to re-install windows, steam and TSW, I did so and hoped the problem would be solved. But today I played on the Lubeck line in the BR101, my character stood up of the chair, I released the Federspeicherbremse sat down, and again my PC turned off. Now a scenario I created myself with the BR101 on the Munich route switched my PC off. No other game I played had this weird issue. At first I was concerned that my CPU was overheating but that was clearly not the case. And it does not happen in any other games. Any ideas?! Edit: Running a Ryzen9 5900x. on a MSI x570 board with an RTX 3090. Not the worst gaming rig but still crashing the entire PC.
