При появлении критических ошибок операционной системы вылезает так называемый синий экран смерти. Хотя с точки зрения программистов его правильно обозначать как BSOD. Это крайне нежелательное явление для любого пользователя. Причём причин появления синего экрана достаточно много.

Как исправить ошибку IRQL_NOT_LESS_OR_EQUAL

Есть распространённый вид BSOD, который сопровождается надписью IRQL_NOT_LESS_OR_EQUAL. Популярная ошибка, справиться с которой можно своими силами. Для этого нужно знать о причинах её появления, а также о предпринимаемых мерах по устранению.

Причины ошибки

Рассматриваемая ошибка появляется в виде надписи на синем экране компьютера в ситуации, когда у операционной системы возникают проблемы со стороны драйверов ПО.

Может изначально показаться, что если дело в связи между драйверами и памятью, тогда причина точно со стороны самого программного обеспечения. Но спешить с выводами не стоит.

В действительности потенциальных причин много. К их числу относятся:

  • повреждение или отсутствие системных файлов;
  • конфликт ОС и нового оборудования;
  • повреждение и потеря актуальности драйверов;
  • поломка винчестера (жёсткого диска);
  • воздействие со стороны вирусов;
  • неисправности материнской платы, оперативной памяти и иных компонентов;
  • проблемы со стороны используемого программного обеспечения.

Поскольку причин достаточно много, все они требуют отдельного и более детального рассмотрения.

Ошибка IRQL_NOT_LESS_OR_EQUAL

Системные файлы

Первым делом, столкнувшись с такой ошибкой как IRQL_NOT_LESS_OR_EQUAL, требуется заняться проверкой возможно повреждённых системных файлов.

ВАЖНО. Если ОС Windows в стандартном режиме не запускается, тогда пуск операционной системы нужно осуществлять через LiveCD или же безопасный режим.

Все действия, которые будут описаны дальше, включая все потенциальные причины появления ошибки, нужно выполнять именно через Безопасный режим, либо с помощью загрузки системы через LiveCD.

Специалисты советуют всегда начинать с проверки файлов своей системы, поскольку это самый простой, но в то же время наиболее эффективный способ справиться с появившимся синим экраном.

ВНИМАНИЕ. Чаще всего ошибка IRQL_NOT_LESS_OR_EQUAL появляется именно на компьютерах и ноутбуках с ОС Windows 10 и Windows 8. На более старых ОС преимущественно возникает код 0x000000d1.

В проверке системных файлов на компьютере или ноутбуке нет ничего сложного. Здесь в ход идёт встроенная утилита. Для запуска диагностики необходимо сделать следующее:

  • комбинацией клавиш Win и R вызвать командную консоль;
  • в открывшемся поле для ввода прописать команду sfc /scannow;Команда sfc /scannow
  • нажать на Enter;
  • дождаться полного завершения диагностики;
  • перезагрузить компьютер.

Пользователю особенно сильно повезёт, если рассматриваемая ошибка будет сопровождаться кодом, указывающий на конкретный повреждённый или проблемный файл. Он может идти с расширением exe или sys. Это указывает на то, что определённые проблемы есть со стороны определённого файла драйвера. Его повреждение и поспособствовало появлению синего экрана смерти. Или просто BSOD.

Драйверы

Довольно часто случается так, что ошибка IRQL_NOT_LESS_OR_EQUAL на дисплее сопровождается конкретным кодом, указывающим на определённый файл в системе. Это хорошо, поскольку так можно быстро отыскать проблемный драйвер.

Для выявления таких файлов удобнее всего использовать утилиту анализа дампа. Она называется BlueScreenView. Именно к её помощи рекомендуется прибегнуть.

Утилита BlueScreenView

Чтобы воспользоваться этой утилитой, требуется, чтобы в ОС была активирована опция для создания дампов. Как только пользователь запустит её, он сразу же увидит проблемные компоненты. Они будут подсвечиваться красным цветом.

Вне зависимости от конкретной операционной системы, есть определённые драйверы, которые провоцируют появление рассматриваемой ошибки и синего экрана смерти чаще всего. Потому их стоит коротко рассмотреть:

  • netio.sys и ndis.sys. Отвечает за работу установленной сетевой карты на компьютере. В этой ситуации рекомендуется обновить драйвер. Пользователям ноутбуков нужно посетить официальный сайт изготовителя портативного компьютера. Если это настольный ПК, тогда источником будет производитель материнской платы. А вот стандартный диспетчер устройств для обновления лучше не использовать. При использовании самой последней версии драйвера сетевой карты его всё равно следует переустановить. Но перед этим попробуйте отключить антивирус. Иногда именно он мешает нормальной работе;netio.sys и ndis.sys
  • nvlddmkm.sys. Либо любой иной файл с расширением sys с буквами nv в начале. Это драйвер, связанный с видеокартой. Причём только бренда Nvidia. Тут можно удалить этот драйвер полностью, а затем скачать его с официального сайта и установить заново;
  • atikmdag.sys. Файл относится к видеокартам AMD. Решение аналогичное;atikmdag.sys
  • strport.sys. Если повреждён этот файл, причину следует искать в подключении через USB или с накопителем. Для начала просто отключите все устройства, исключая лишь клавиатуру и мышь. Проверьте, всё ли в порядке с SSD накопителем, если он используется. Далее сбросьте в BIOS настройки и перезапустите систему;
  • dxgmms2. Ещё один потенциальный виновник с расширением sys, как и все последующие. От него зависит работа видеокарты. Тут рекомендуется переустановить софт для видеокарты, а также отключить аппаратное ускорение, если оно применялось;Ошибка из-за драйвера dxgmms2
  • usbehci. Отвечает за драйвер USB контроллера. Выход один. Переустановить его;
  • cmaudio. Связан со звуковой картой. Драйвер следует сначала удалить, а затем переустановить его;
  • wfplwfs. Чаще всего имеет отношение к антивирусному программному обеспечению. Причём это касается конкретных программ в лице McAfee, Eset и Comodo. Но иногда файл связан с драйверами сетевой карты;
  • tcpip. Из названия понятно, что речь идёт о драйвере протокола TCP/IP. Для исправления ошибки иногда достаточно просто отключить антивирус. Если не помогает, тогда нужно обновить ПО от сетевой карты. Ещё стоит ввести команду «netsh int ip reset» и перезагрузить ПК.Ошибка из-за tcpip.sys

ВАЖНО. Часто все эти ошибки идут параллельно с ntoskrnl.sys, связанной с ядром ОС. Если же при анализе дампа вылезает только этот файл, то тут причина наверняка в самой сборке ОС Windows.

В такой ситуации выхода два. Это переустановка операционки либо установка совершенно новой ОС.

Как только пользователь устранит проблему, связанную с драйвером, синий экран смерти перестанет появляться.

Конфликты оборудования

Также такая проблема как ошибка IRQL_NOT_LESS_OR_EQUAL может появляться по причине конфликта оборудования. То есть пользователь подключает устройство или устанавливает программное обеспечение, являющееся несовместимым с конкретной версией ОС.

Чтобы в этом убедиться, можно изучить спецификации оборудования или ПО либо же отключить его, удалить с компьютера. Если ошибка уйдёт, причина найдена.

Если проблем с совместимостью ОС и оборудования нет, тогда причина неполадок в программном обеспечении, с помощью которого осуществляется работа устройства. Опять же, нужно убедиться, что загруженная или установленная версия ПО соответствует вашей Windows. К примеру, по версии, либо по разрядности.

Проверка битности

Винчестер

Вовсе не исключено, что код остановки в виде IRQL_NOT_LESS_OR_EQUAL появится, если выйдет из строя накопитель. Поломки винчестеров – не редкость, поскольку у них срок службы ограничен. Со временем они начинают постепенно сыпаться, повреждаются сектора, появляются посторонние звуки.

Столкнувшись с такой ошибкой и исключив другие вероятные причины, рекомендуется провести диагностику жёсткого диска. Если это возможно, выполняется ремонт, восстановление. Либо же приходится менять накопитель на новый.

Вирусы

Ещё одна причина, из-за которой может появляться код неисправности в виде ошибки IRQL_NOT_LESS_OR_EQUAL, связана с вредоносным программным обеспечением и вирусами.

Попадая на компьютер, они могут повредить или заменить важные файлы, поменять записи реестра, что и ведёт к сбоям в работе.

Проверка компьютера на вирусы

Решение только одно. Это установка заведомо эффективного антивирусного софта с последующей проверкой всего компьютера. Дополнительно стоит очистить и исправить записи в реестре, используя специальные утилиты.

Материнская плата

Также синий экран с надписью IRQL_NOT_LESS_OR_EQUAL может появляться, если выйдет из строя материнская плата либо какие-то её отдельные компоненты. Для устранения синего экрана смерти придётся поочерёдно вытащить все планки, переставить в другой разъём, и проверить, поменяется ли поведение компьютера.

Ещё стоит провести проверки оперативной памяти с помощью встроенного инструмента либо же специальными программами. Если речь идёт о физических повреждениях, то тут поможет лишь ремонт или замена.

Программы

Как ни странно, но одна из распространённых причин, почему появляется ошибка IRQL_NOT_LESS_OR_EQUAL на компьютерах с ОС Виндовс, заключается в обычных на вид программах и самом антивирусном софте.

Установленные программы

Чтобы решить проблему, можно попробовать удалить весь софт, который был установлен за последнее время. Если какие-то программы устанавливались буквально перед появлением синего экрана, то тут всё наверняка очевидно. Начните с удаления этого софта.

Дополнительные меры

Есть ещё 2 способа, которые могут помочь.

Пользователям предлагается сделать следующее:

  1. Восстановить систему. Для этого должна быть доступна точка восстановления. Если их несколько, выбирайте ту, которая наиболее свежая, чтобы сильно не откатывать систему назад и не терять ряд полезной и важной информации, сохранённой за последнее время.
  2. Обновить ОС. На многих компьютерах отключена функция автоматического обновления операционной системы. Если ОС давно не получала обновления, это можно сделать вручную. Либо просто активируйте автообновление, чтобы в дальнейшем все свежие пакеты компьютер получал при загрузке ОС.

Такую ошибку как IRQL_NOT_LESS_OR_EQUAL нельзя назвать редким явлением. Но и далеко не всегда она обусловлено какими-то серьёзными и опасными причинами, на устранение которых придётся потратить много ресурсов, включая время и деньги.

Но всё же при любых обстоятельствах сталкиваться с синим экраном смерти не хочется. Предупредить и предотвратить его появление практически невозможно. Но, зная потенциальные причины, всегда можно оперативно предпринять ряд мер и восстановить нормальную работоспособность операционной системы и всего компьютера либо ноутбука.

All Windows users, at some point, have had problems with a Blue Screen of Death (BSOD). Some Windows 10 users have reported encountering the MSDN bugcheck IRQL_NOT_LESS_OR_EQUAL error.

These can be caused by incompatible drivers or hardware malfunctions, and Windows 10 users have not seen the end of it.

In this guide, we will try to shed some light on the IRQL_NOT_LESS_OR_EQUAL error in Windows 10 and the best solutions for it.

What does IRQL_NOT_LESS_OR_EQUAL mean?

The Stop Code IRQL_NOT_LESS_OR_EQUAL basically means that a process, application, or installed driver is trying to access a part of the system that it doesn’t have permission.

When a device driver or kernel process tries to access a memory location to which it isn’t authorized to have access, the operating system will issue an error. The same is true if a piece of software is corrupted and tries to access the wrong memory addresses.

Also, it could arise due to conflicts between two drivers when both try to write a memory allocation simultaneously. If any of this happens, the OS crashes with the IRQL_NOT_LESS_OR_EQUAL BSOD error.

BSOD IRQL_NOT_LESS_OR_EQUAL causes

The error may be caused due to overclocking or software meant to enhance the computer’s performance. Problematic drivers are also a probable underlying cause.

Also, if the system files are damaged or corrupt, the OS may throw this or other BSOD errors. Besides, problems with the RAM or other hardware are just as likely to cause the Blue Screen IRQL_NOT_LESS_OR_EQUAL error.

Here are some of the other cases you encounter the error in Windows:

  • IRQL_NOT_LESS_OR_EQUAL ntoskrnl.exe, netio.sys, MSDN bugcheck: As a quick reminder, this executable file is the kernel (core) of the operating system and usually indicates that the issue is pretty severe.
  • IRQL_NOT_LESS_OR_EQUAL Overclock: Many gamers confirmed that they often experienced this error after overclocking their computers. As a result, disabling overclocking may fix this error.
  • IRQL_NOT_LESS_OR_EQUAL CPU overheating: Overheating in the CPU may cause this error. As stated above, do disable overclocking to reduce overheating. Using dedicated cooling software and a cooling pad may also reduce the frequency of this issue.
  • IRQL_NOT_LESS_OR_EQUAL after RAM upgrade in Windows 7, 10, 11: Some users reported that this BSOD error occurred shortly after they upgraded their RAM. Make sure that the new RAM is compatible with your device and that it’s properly installed.
  • IRQL_NOT_LESS_OR_EQUAL after Windows update, on boot, on startup: In rare cases, this error may occur after installing the latest Windows updates. As a result, uninstall the updates and check if the issue persists.
  • IRQL_NOT_LESS_OR_EQUAL and Memory_Management: Sometimes, these two BSOD errors go hand in hand. Users reported that when the first error occurs, the second one follows it after reboot.
  • IRQL_NOT_LESS_OR_EQUAL virus: Perform a virus scan with your antivirus in order to remove any malicious software.

Let’s now find out how you can fix IRQL_NOT_LESS_OR_EQUAL in Windows 10 and the latest iteration.

NOTE

If your motherboard’s BIOS has the Memory Caching feature, then you should disable this feature. Remember that operating in the BIOS environment can be dangerous, so do not attempt to modify other settings if you don’t know what they do.

The next step is to check the hardware You will need to unplug all non-essential devices from your computer (which basically means everything except your mouse and keyboard) and then disable their drivers.

After a reboot, check to see if all the drivers are still disabled and, one by one, re-enable and reconnect the devices. Do not plug in or enable more than one device at a time!

If the error does not appear, then that device and driver are clear, and you can move on to the next one. Do this until you have either added and enabled all the devices or the BSOD appears.

If the latter happens, this means that the driver enabled last is the underlying cause. Boot your PC into Safe Boot, completely uninstall it, and then update the driver. Also, if the Windows 10 Stop Code IRQL_NOT_LESS_OR_EQUAL appears after a driver update, try rolling back the driver.

4. Refresh or restore

A memory problem mostly causes the IRQL_NOT_LESS_OR_EQUAL error. The IRQL component refers to the «Interruption ReQuest Line», and Windows uses it to notify occurrences that need immediate attention. When a device driver asks for entry to a memory location for which it does not have the required approval or access privileges, IRQL occurs.

Because memory allocations for processes often have a fixed border, the «NOT LESS OR EQUAL» section of the error indicates that the driver tried to access an address that was either outside or larger than the boundary value.
