Если при работе вы столкнулись с ошибкой (синим экраном) DRIVER_IRQL_NOT_LESS_OR_EQUAL, кодом 0x000000d1 и указанием сбойного модуля ndis.sys, вероятнее всего проблема в работе сети. NDIS — это Network Driver Interface Specification, в свою очередь ndis.sys — драйвер интерфейса для работы операционной системы в сети.
В этой инструкции — способы исправить ошибку 0x000000d1 ndis.sys в Windows 10, 8.1 или Windows 7 и устранить появление синего экрана DRIVER_IRQL_NOT_LESS_OR_EQUAL ndis.sys. Про эту же ошибку с другими файлами драйверов в отдельной инструкции: Как исправить ошибку DRIVER_IRQL_NOT_LESS_OR_EQUAL 0x000000d1.
Исправление ошибки ndis.sys 0x000000d1
Наиболее частыми причинами синего экрана (BSoD) DRIVER_IRQL_NOT_LESS_OR_EQUAL ndis.sys являются неправильная работа драйверов сетевой карты или влияние стороннего ПО на их работу, в частности, это может быть сторонний антивирус. В списке ниже — способы исправления проблемы от более простых к более сложным:
- При наличии точек восстановления системы на дату, предшествующую появлению ошибки, попробуйте использовать их, см. Точки восстановления Windows 10 (для предыдущих версий ОС всё то же самое).
- Загляните в диспетчер устройств, откройте свойства используемой сетевой карты и проверьте, активна ли кнопка «Откатить» на вкладке «Драйвер». Если да — попробуйте использовать её.
- Если проблема появилась после установки новой версии Windows 10 (после «большого» обновления), а на вашем компьютере находился сторонний антивирус, попробуйте полностью удалить его (лучше использовать утилиту удаления от разработчика антивируса), обязательно перезагрузить компьютер и посмотреть, возникает ли ошибка снова. Если нет — можно установить антивирус повторно, синий экран не должен появиться снова. Сбои в работе антивирусов после обновления компонентов Windows 10 — достаточно распространенная вещь.
- В случае, если вы устанавливали на компьютер какие-либо программы для работы с VPN/Прокси и прочей анонимизации в сети, попробуйте отключить или удалить их и проверить, исправит ли это проблему.
- Перезагрузите компьютер в безопасном режиме (см. Как зайти в безопасный режим Windows 10), откройте диспетчер устройств и удалите сетевые адаптеры. Затем в диспетчере устройств в меню выберите «Действие» — «Обновить конфигурацию оборудования» и дождитесь переустановки драйверов. Перезагрузите компьютер в обычном режиме.
- Если проблема появилась после чистой установки системы на компьютер и последующей установки драйверов (особенно с помощью различных драйвер-паков), не поленитесь и скачайте драйвер сетевой карты или Wi-Fi адаптера с официального сайта производителя материнской платы (если у вас ПК) или ноутбука, именно для вашей модели. А затем вручную установите его, даже если диспетчер устройств сообщает, что драйвер не нуждается в обновлении, а на официальном сайте драйвер только для предыдущей версии ОС.
- Если на вашем компьютере установлена Windows 10 и ранее она работала без ошибки, попробуйте выполнить автоматический сброс сетевых настроек.
- Если недавно вы устанавливали виртуальные машины (например, VirtualBox) и соответствующие им виртуальные сетевые адаптеры, это может послужить причиной ошибки ndis.sys, попробуйте удалить виртуальный сетевой адаптер.
Обычно, один из приведенных методов позволяет избавиться от синего экрана, вызываемого ndis.sys, но не всегда.
В случае, если вышеописанные способы не помогли, попробуйте использовать дополнительные подходы, в редких случаях они помогают.
Дополнительные методы исправления ошибки
- Используйте встроенное устранение неполадок сети (если еще не делали этого). Как именно описывалось в инструкции Устранение неполадок Windows 10 (способ с панелью управления работает и для предыдущих версий).
- Попробуйте выполнить проверку целостности системных файлов Windows.
- По некоторой информации (не могу подтвердить или опровергнуть) ошибка может быть вызвана сбоями файловой системы на диске, попробуйте выполнить проверку жесткого диска на ошибки.
Ну и, наконец, последний способ, если ничто не помогает решить проблему, а она не является аппаратной и не вызвана проблемами с электропитанием, статическим электричеством или поврежденными кабелями, остается переустановка или сброс Windows.

DRIVER_IRQL_NOT_LESS_OR_EQUAL is a blue screen of death error caused by corruption of files or drivers.
Ndis.sys is a legitimate system driver of the network interface controller. However, scammers quite often exploit the names of important system files and disguise malicious software under them.[3] Besides, files like ndis.sys are a target of viruses because once corrupted they call out errors, system crashes, freezes, which is why OS gets more vulnerable.

1. Change Hard Disk Policies
It is possible that if you enable write caching on your hard disk, it may solve the problem of corrupted NDIS.sys. To do this, follow these steps:
- Press Windows + R to launch the Run window and type devmgmt.msc and hit Enter.
- This will open the Device Manager window on your PC. Expand the Disk Drives and then right-click on your HDD/SSD drives.
- Now, click on Properties and go to the Policies tab.
- Check the option to Enable Write caching on the device.
- Click on OK to save the changes and close the Device Manager window.
Now, you can restart your computer and see if the issue is fixed.
2. Perform Memory Diagnostics in Safe Mode
As we mentioned earlier, corrupted NDIS.sys could be the main reason behind this error, which is why we will perform memory diagnostics in safe mode to check if the memory is corrupted.
- To do this, press Windows + R and open the Run dialog box. Type ms-settings:recovery inside the box and press Enter.
- Now, go to Recovery > Advanced Startup and click on Restart Now.
- Click on Troubleshoot > Advanced Options from the options and then click on Startup Settings.
- Click on Restart, then press 4 to restart your PC in safe mode.
- Once your PC gets restarted in safe mode, open the Run dialog box by pressing Win+R.
- Type mdsched.exe and press Enter.
- This will open the Windows Memory Diagnostic window.
- In this window, select the option to Restart Now and Check for problems (recommended)
Now, your PC will be restarted, and the system will check if there are any problems with your memory. If there are problems found with your memory, the system will try to fix them and solve your problems the next time you reboot your PC.
3. Perform Check Disk Operation
If you have found out that your memory is fine, then you should also check the disks on your PC to ensure they are working fine. To perform the Check Disk operation on your PC, follow these steps:
- Click on the Windows button, type CMD, and click on Run as Administrator to open CMD in admin mode.
- Accept the permissions as prompted.
- Now, type the following command in your CMD window:
chkdsk /f /r <drive letter>
Note: Replace the <drive letter> with your respective drive. For example, if you want to check the C drive, then the format will be:
chkdsk /f /r C:
- Check all the drives on your PC one after the other and see the results.
- Reboot your PC after all the drives have been checked, and your problem should be solved by now.
4. Run System Restore
If your issue is still not fixed, then the last option is to revert your system to a point where everything is working fine.
Basically, this is known as System Restore, and Windows already creates System Restore points on the PC so that you can revert back to it if something goes wrong. To go back to a System Restore point in the past, follow these steps:
- Go to Windows Start Menu, type Control Panel, and open the first result.
- Now, go to this path: Control Panel\All Control Panel Items\Recovery by copying and pasting it into the address bar at the top.
- Click on Open System Restore, and you will be shown the best system restore point for your PC.
- If you are fine with it, click on Next and follow the on-screen instructions to restore your system to that point.
- Note that if you have made any changes to the system after the system restore point was created, those changes will be lost.
But we are sure that this will fix all the issues you are having, which is why we recommend you restore the system to that point.
