Hi my pc. 9900K stock turbo 4.7 . All auto settings in bios. VOLTAGE on AUTO. Noctua NH-D15 .Temps 60-70C 2x16 GB DDR4 GSKILL 3000 XMP Corsair 850RmX Aorus 2080 Ti Xtreme , no oc,stock. All stress tests passing fine. I dont have any crashes in game. But few days ago, i go out to work, and i left running game BF 5. When i back,game was running 13 hours,and in 14 hour ( it was 3 am ) it crashed to desktop. Event viewer nothing said. No error message,no display crash. Just exit to desktop. Game just was on 14 hours,and after moment it go to desktop withour error message. I dont touch anything,game was in campaign mode,when character is standing on the same place. Now i am testing again and see if i can reproduce, but i cant. I am currently on 80 hour and not crashed again. Is this reason to worry?My drivers are the newest. Maybe XMP issue or auto voltage? Or issue with game?
