В последние пару дней экран периодически чернеет, монитор переходит в спящий режим. Перейти в консоль по C-A-F1 не получается. За то можно зайти по SSH. В /var/log/messages есть такое:

В логах xorg ни какого криминала. Что это может быть? Недавно обновил видюху. Но около недели такого не наблюдалось, а тут началось. Грешу на проблемы по питанию. БП 450Ватт, видео GTX560.
