BSOD или синий экран смерти KERNEL THREAD PRIORITY FLOOR VIOLATION с кодом 0x00000157 возникает на различных сборках Windows по причине аппаратной и программной поломки. Поскольку на официальном сайте Майкрософт нет указания на точную причину BSOD, то для её определения нужно включить малый дамп памяти и проанализировать полученный файл с помощью программы BlueScreenView.

Читайте также: Методы исправления ошибки 0x00000156: WINSOCK DETECTED HUNG CLOSESOCKET LIVEDUMP на Windows 8

Как исправить BSOD 0x00000157: KERNEL THREAD PRIORITY FLOOR VIOLATION на Windows 7?

Поскольку официальных рекомендаций по исправлению ошибки 0x00000157: KERNEL THREAD PRIORITY FLOOR VIOLATION на сайте Майкрософт нет, то, проанализировал зарубежные форумы, выделим способы, к которым прибегали пользователи Windows 7 и не только для решения проблемы.

Так, на одном из зарубежных форумов указано, что синий экран смерти KERNEL_THREAD_PRIORITY_FLOOR_VIOLATION возникала на ПК с Windows 7 при запуске онлайн игр. При этом ПК после вылета ошибки перезагружался. Виновником BSOD оказался видеодрайвер. Для решения ошибки стоит переустановить ПО для видеокарты. Сделать это можно следующим образом:

Жмем «Win+R» и вводим «devmgmt», чтобы открыть «Диспетчер устройств».

Разворачиваем ветку «Видеоадаптеры». Нажимаем на названии видеокарты правой кнопкой мыши и выбираем «Обновить драйвера».

Появится небольшое окно. Выбираем «Выполнить поиск драйверов на этом компьютере».

Указываем путь к ранее загруженному драйверу.

Позволяем Windows обновить драйвера. Перезагружаем систему, чтобы изменения вступили в силу.

ВАЖНО! В некоторых пользователей данную ошибку вызывал аудиодрайвер. Поэтому нужно проанализировать состояние всех установленных драйверов и при необходимости обновить их все.

Еще на одном форуме пользователи указывали, что ошибка 0x00000157 появлялась на их ПК по причине вирусного заражения системы и повреждения системных файлов. При этом стандартный инструмент sfc /scannow не помог исправить ошибку. В данном случае нужно воспользоваться опцией по восстановлению системы с установочного диска. Для этого нужно подключить к ПК установочный диск или флешку с той же версией и разрядностью операционной системы, что и установлена. Далее кликнуть не «Установить», а «Восстановление системы».

Появится небольшое окно. Нужно выбрать «Восстановление системы».

Запустится восстановление Windows. После завершения процесса и перезагрузки ПК нужно извлечь диск или флешку и проверить систему на наличие или отсутствие ошибки.

Если же вы занимались разгоном оперативной памяти или процессора и применяли для этой цели фирменные утилиты от производителей устройств, то нужно сбросить настройки до заводских и удалить специальные программы. Иногда, именно фирменные утилиты вызывают BSOD 0x00000157: KERNEL THREAD PRIORITY FLOOR VIOLATION.

В случае, если вы не разгоняли ни одно из установленных комплектующих системной сборки, на ПК нет вирусов и драйвера находятся в актуальном состоянии, рекомендуем провести полную диагностику всего ПК и откатить Windows 7 до более раннего состояния или вовсе выполнить чистую инсталляцию операционной системы.

Синий экран смерти 0x00000157 означает, что была предпринята попытка запрещенной операции на уровне приоритета конкретного потока.

Данная ошибка встречается крайне редко.

РЕШЕНИЕ

ОБЩИЕ СВЕДЕНИЯ ОБ АВАРИЙНОМ ДАМПЕ ПАМЯТИ
Все Windows-системы при обнаружении фатальной ошибки делают аварийный дамп (снимок) содержимого оперативной памяти и сохраняет его на жесткий диск. Существуют три типа дампа памяти:

Полный дамп памяти – сохраняет все содержимое оперативной памяти. Размер снимка равен размеру оперативной памяти + 1 Мб (заголовок). Используется очень редко, так как в системах с большим объемом памяти размер дампа будет слишком большим.

Дамп памяти ядра – сохраняет информацию оперативной памяти, касающуюся только режима ядра. Информация пользовательского режима не сохраняется, так как не несет в себе информации о причине краха системы. Объем файла дампа зависит от размера оперативной памяти и варьируется от 50 Мб (для систем с 128 Мб оперативной памяти) до 800 Мб (для систем с 8 Гб оперативной памяти).

Малый дамп памяти (мини дамп) – содержит довольно небольшое количество информации: код ошибки с параметрами, список драйверов загруженных в оперативную память на момент краха системы и т.д., но этих сведений достаточно, для определения сбойного драйвера. Еще одним преимуществом данного вида дампа является маленький размер файла.

или

Для устранения ошибки воспользуйтесь одним или несколькими способами.

1. Сперва необходимо проверите наличие свободного места на системном разделе жесткого диска. Если свободного места мало, то необходимо его увеличить, удалив ненужные данные;

2. Просканируйте операционную систему антивирусными программами для удаления всевозможного нежелательного программного обеспечения, коими являются вирусы, трояны и т.д.;

3. Большое количество BSoD появляется вследствие ошибок кода самой операционной системы. Компания Microsoft постоянно работает над исправлением таких ошибок, выпуская патчи и пакеты обновления. Установленный последний пакет обновлений (Service pack) и постоянное обновление системы избавят от большого количества ошибок. Рекомендую установить радиокнопку автоматического обновления системы.

4. Если ошибка появилась после недавно установленного драйвера устройства или программы. Необходимо откатить драйвер на более раннюю версию. С программами дела обстоят проще, их удаление устранит причину сбоя. Может пригодиться опция “Запуск последней удачной конфигурации” системы.

5. Если синий экран начал появляться после того как Вы подключили новое устройство к системе, то необходимо проверить его на совместимость с Вашей операционной системой. Если устройство совместимо, то необходимо скачать свежие драйвера с официального сайта производителя и установить их. Если установлена последняя версия драйверов, то необходимо установить более раннюю версию драйверов. Если устройство несовместимо с операционной системой, то необходимо, либо поменять данное устройство, либо поменять операционную систему, поддерживающую данное устройство.

6. Установите настройки BIOS по умолчанию. Неправильные настройки BIOSа могут привести к печальным последствиям. И экран смерти это не самый худший вариант. Если Вы не уверенны в своих навыках, то в BIOSе лучше ничего не менять.

7. Очень часто причиной появления BSoD является неисправность оперативной памяти. Для её проверки можно использовать тестирующие программы, например memtest86+. В случае выявления битой линейки памяти, её необходимо заменить. При использовании в компьютере двух планок памяти и более, устранение неисправной устранит сбой.

8. Проверьте жесткий диск на наличие битых секторов и ошибок. По возможности исправьте ошибки и восстановите битые сектора стандартными средствами системы.

9. Необходимо избавиться от перегрева компонентов ПК. Почистите Ваш компьютер от пыли, смажьте специальным маслом все кулеры (процессорный, чипсетный, видеокарты, блока питания). При необходимости, установите дополнительные кулера, для организации правильного потока воздуха в системном блоке.

10. Проверьте правильность подключения кабелей и комплектующих. Посмотрите на их контакты, при необходимости смажьте их.

11. Переустановите операционную систему. Используйте только лицензионный диск операционной системы. Использование различных сборок приводит к постоянным проблемам.
