my son's SER6 Pro 6800H with the latest 1.13/1.15 BIOS restartad 3 times in the last week while he played the game, could you advise me how could I find out what was the reason of the restart?
Maybe I need to start a logging software?
You can use Event Viewer in Windows and check there the Windows Logs, System and Application tabs. If Windows logged what happened, you will find there and maybe fix the cause. Right click on Start, Event Viewer.
