После первого обновления программного обеспечения на Ubuntu 14.04 компьютер загружается на черный экран

Я дважды установил Ubuntu 14.04 на свой компьютер Dell OptiPlex 990. Оба раза после первого обновления программного обеспечения компьютер загружается на черный экран. Я думал, что это проблема с видеодрайвером, поэтому во второй раз перед обновлением программного обеспечения я сменил общие драйверы на проприетарные. Я пробовал много вещей, чтобы попытаться восстановить установку Linux, но ничего не помогло. Я установил Ubuntu 14.04 в третий раз, но теперь я не установил обновления программного обеспечения. Что мне делать?

Мой профиль оборудования можно найти здесь .
