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 ) "a callout to win32k did not return promptly" windbg read I tested other games no single issue. Memtest86 no errors,ramtest fine.realbench ok. I cant reproduce issue ,it happened once. But i am bit worried about that reboot ( Kernel 41 ). Any ideas?
