Ubuntu 16.04 LTS начал работать очень медленно

Question

Моя конфигурация системы

Memory : 2.8 GiB
Processor : Intel® Core™ i5-2430M CPU @ 2.40GHz × 4
Graphics : Intel® Sandybridge Mobile
OS type : 64-bit
Disk : 126.1 GB

Я установил Ubuntu 16.04 на шесть месяцев назад, дважды загрузился вместе с Windows 7. Он работал бесперебойно в течение нескольких месяцев, но в последнее время он начал замедляться. Для переключения окон требуется некоторое время, и иногда окно зависает и становится серым. Я использую браузер Chrome, который также работает медленнее.
