Играл в игру в steam через протон. Скорей всего упал nvidia-driver, который ребутнул систему. Но надо точно это промониторить

Симптоматика такая: играю, монитор уходит в sleep, потом включается и я вижу как загружается тачка. Скорей всего, nvidia драйвер крашнулся и никуда не успело ничего записаться. Только вот это

Товарищи, играл с выключеннным светом. Видимо свет мигнул и тачка тупо ребутнулась. Как задетектил? Свет моргнул пару раз этим вечером. Всем спасибо
