Зависает, мигает CapsLock

[YDenis]

Здравствуйте.
Подскажите пожалуйста. Ноутбук Lenovo G570, Ubuntu 11.04. Недавно появился трабл. Система виснет наглухо, при этом часто мигает индикатор CapsLock. Что это может быть?

Спасибо

память проверь. Выткни планки по очереди и втыкни их обратно в разные разъемы

Сделал. Но все равно зависает.
Причем 100% зависание идет если на ноуте расшарить папку, он поключен к роутеру по wifi. К этому ноуту так же через wifi подключаю другой ноут с такой же системой. Начинаю забирать информацию с расшаренной папки и через пару секунд висяк. И так всегда.

PS Сейчас попробовал наоборот с проблемного ноута скинуть на расшаренную папку на другом ноуте - висяк.

Условия все те же. Пытаюсь закинуть на расшаренную папку большой файл (500Мб). если ноут подключаю по меди - нормально копирует. Но как только отключаю медь, ноут переходит на wifi, 10-15Мб переслал и тут же завис.
Help! Что с wifi не так?
Пользователь решил продолжить мысль 08 Октября 2011, 18:57:46:Хм. Вот еще странность. Все тот же ноут, Lenovo G570. У него на корпусе есть флажок, отключающий wifi. Если отключить, то сеть теряется - логично. Но если вернуть флажок обратно на ВКЛ, то система зависает. Но capslock не мигает.
Fn+F5 без проблем включает и отключает wifi.

подпишусь. G570, i3, видео встроенное, ubuntu 11.04. зависает наглухо, индикаторами не мигает. причем очевидных закономерностей нет. может зависнуть через 10 минут после включения, а может трое суток проработать до выключения без сбоев. интернет получает по wifi, сношений с другими компьютерами по сети не имеет.

проделывал те же манипуляции (выкл\вкл аппаратным переключателем) - после включения wifi система не зависает.
memtest который штатный (в меню grub) не стартует, проверял средствами Windows 7. тест ошибок памяти не выявил.
добавлял в grub опцию "pci=nomsi", эффекта не дало.

Зависание произошло в 9:28, но в это время событий нет, кроме лога загрузки (или не те логи?)
На забугорном форуме нашел предположение, что конфликтуют драйвера lan и wifi карт. Рекомендовали занести модуль lan в черный список. Проделал - не помогло.
==================================================
Обновил до 11.10,  две недели - полет нормальный. Надеюсь, решилась проблема
==================================================
Наша песня хороша - начинай сначала. Обновил до 12.04 - здрасти зависания =(
