Hi. My question. I had a crash in Metro Exodus after 20 hours ,during exiting to MAIN MENU. Black screen,crash to desktop and unexpected reboot.

After crash to desktop i decided to log out from system and log back in again,and then system rebooted unexpectedly.

Why system rebooted after the crash? It happened once. Before reboot file appeared: --> PoW32kwatchdog.dmp
But i found this in windows/livekernelreports/PoW32kwatchdog.dmp <======== ( 1,8GB )
