Используя системный журнал для определения причины частых отказов запустить Ubuntu 16.04 LTS

Мой набор находится на Dell Precision 380 с 4 ГБ RAM, Intel® Pentium(R) 4 CPU 3.00GHz × 2, Галлий 0.4 на NVA8. Ubuntu 16.04 находится в разделе на 67 ГБ, другой раздел имеет Победу XP, но это не работало в течение долгого времени. Жесткий диск прошел тест без проблем.

Признак - то, что в течение прошлых нескольких недель приблизительно 50% системы запускаются, получают меня через страницу входа в систему, но не удаются прогрессировать до рабочего стола. Иногда перезагружая работы, другие времена я должен обратиться к опциям или универсального или даже режим восстановления. Я копирую ниже вывода системного журнала после успешной перезагрузки, которые показывают s несколько странных продолжений, которые могли бы объяснить, почему система медленнее для загрузки, чем это раньше было:
