Случайное замораживание с Ubuntu 14.04

Установил Ubuntu 14.04 и система зависает как минимум раз в день в случайные моменты времени.

Под "зависанием" я подразумеваю, что клавиатура и экран мыши вообще не реагируют. Это произойдет независимо от того, работает ли система, или она простаивает с включенным экраном блокировки.

Мне приходилось держать кнопку питания на моем dektop (powerwash), чтобы перезапускаться каждый раз.

В моем журнале var/logs/syslog похоже, что были процессы, запущенные даже после зависания экрана. Учитывая, какие задачи были выполнены, я считаю, что система зависла где-то между 11 и 12. 12:50 - это когда я перезагружал рабочий стол.

Если кто-то может увидеть проблему в моем системном журнале или сказать мне, где еще искать, это было бы очень полезно. Я даже не знаю, с чего начать.
