Рабочее решение для ОС Windows 7/8/8.1/10
Синий экран смерти (BSOD) с ошибкой:
PAGE_FAULT_IN_NONPAGED_AREA (ETD.SYS)
или
SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (ETD.SYS)
Характерная ошибка в большинстве случаев для ноутбуков, возникает в связи со сбоем драйвера тачпада на ноутбуке. Проблема частая для ноутбуков с Elan и Synaptics драйверами на тачпад.
Частая проблема на старых моделях ноутбуков, которые обновились с ОС Windows 7 до ОС Windows 10. Основная причина возникновения ошибки, связанна с автоматической установкой драйвера через Центр обновления Windows. Если вы, обновили свою систему на новую, после активации системы, сделайте чистую установку системы, с полным форматированием системного раздела. При установке, отключите Интернет (читайте в самом низу данной заметки).
Многократно сталкивался с данной проблемой на ноутбуках lenovo b580c, где происходило поверхностное обновление системы с ОС Windows 7 на ОС Windows 10 и автоматом обновлялись драйвера для тачпада.
Ошибка с файлом ETD.sys может возникнуть и на тех устройствах, где была выполнена чистая установка системы, однако не отключалось автоматическое обновление драйверов через Центр обновления Windows. Для тачпада, устанавливайте драйвера с оф. сайта производителя своего устройства. Либо, откажитесь от установки данного драйвера (тачпад не будет работать), если нет официальной поддержки драйвера для ОС Windows 10.
Повторюсь, если у вас старый ноутбук, произведите чистую установку системы и при установке, отключите Интернет (не подключайтесь к Интернету. Далее, сразу после установки, отключите автоматическое обновление драйверов через Центр обновления Windows и установите драйвера для ноутбука с официального сайта (читайте в самом низу данной заметки).
Решение ошибки с файлом ETD.sys.
Если у вас ОС Windows 10, данная проблема возникла скорее всего по причине автоматического обновления драйверов на ноутбуке, через Центр обновлений Windows. При этом, прежде, чем приступать к решению проблемы, проанализируйте после чего возникла данная проблема. Возможно, будет достаточно восстановит систему через контрольные точки и отключить автоматическое обновление драйверов (смотрите ниже).
Универсального и 100% способа решить проблему нет. Ниже, способы решения проблемы, приведены в той последовательности, в которой лучше их выполнять. Данные способы, рассчитаны на опытных пользователей.
1. Удаление драйвера ETD.SYS.
Если невозможно загрузить систему (из-за постоянного экрана смерти BSOD), вам нужно несколько раз неудачно запустить ОС (нажать на выключение во время её загрузки) чтобы у вас открылось меню восстановления, и в нём через командную строку вам нужно выполнить удаление драйвера ETD.SYS.
В среде восстановления, выберите Командная строка
и выполните команду:
del C:\windows\system32\drivers\ETD.sys
Вместо С указываете ваш диск, где установлена ОС Windows.
Для проверки, на каком диске установлена система, можете перед выполнением вышеприведенной команды, выполнить в Командной строке, следующую команду:
notepad
И нажмите Enter. Откроется блокнот, в котором вам нужно будет выбрать Файл->Открыть…
Выбираем в открывшемся
окне «Этот компьютер» и в параметрах «Тип файлов»,
выбираем «Все».
Далее, находим свой диск, на котором установлена именно система. Он может быть не
под той буквой, которую вы видите при работе из загруженной системы Windows
(нередко, системные разделы в среде восстановления, бывают под буквами C, E, F,
D, A, Х). Запомните букву системного раздела и закройте блокнот.
Теперь, можете выполнить в Командной строке, команду удаления (смотрите выше) драйвера ETD.SYS.
После удаления драйвера ETD.SYS, система может загрузиться, а может и не загрузиться. Если вам данный способ помог, отключите временно или на постоянно обновления системы. Лучше, сделать это при помощи простой утилиты:
https://www.oo-software.com/en/shutup10
И запретите автоматически устанавливать обновления для драйверов.
Через данную утилиту, вы можете полностью отключить обновления, однако не рекомендую вам этого делать. Достаточно будет отключить установку обновлений для драйверов, через Центр обновлений Microsoft.
Обратите внимание, что у вас перестанет работать тачпад. Вы можете попробовать установить родные драйвера с официального сайта своего ноутбука. Не используйте программы для автоматического обновления драйверов.
2. Если способ выше — не помог.
Попробуйте отключить сбойный драйвер ETD.SYS.
Если у вас работает система и удается загрузится на Рабочий стол (как вариант, попробуйте через Безопасный режим), скачайте утилиту Autoruns.
Распакуйте архив и запустите утилиту. В открывшемся окне, перейдите во вкладку Драйвера (Drivers)
и найдите драйвер ETD. Отключите его:
Перезагрузите систему и понаблюдайте за работой.
Тачпад, как и в первом способе, перестанет работать. Параллельно, отключите автоматическое обновление драйверов через Центр обновления Windows. Инструкцию, как это сделать, смотрите выше. И можете попробовать установить драйвера для ноутбука с официального сайта.
3. Откат системы.
Если у вас начались проблемы после установки обновлений Windows или вы, обновили драйвера сторонним софтом (программой для поиска и установки драйверов), откатите систему, воспользовавшись точкой восстановления. После, отключите автообновление драйверов.
Как вариант, если удастся, загрузитесь в Безопасном режиме и воспользуйтесь утилитой
Autoruns. Либо, восстановите систему через контрольную точку восстановления.
4. Ничего не помогает (для опытных!).
Попробуйте восстановить ветку реестра из резервных копий, по данной инструкции. Данный способ актуален, если у вас ОС Windows 7 или ОС Windows 10, версии 1709 или старее (на новых версиях, начиная с версии 1803, данный способ не работает).
Заключение.
Попробуйте полностью переустановить систему и после установки, сразу отключите автообновление. Для удобства, вы можете перед установкой системы, отключить Интернет (или не подключатся по Wi-Fi). Скачайте официальный образ системы с оф. сайта Microsoft, при помощи данной утилиты. Обновляйте драйвера для ноутбука с официального сайта производителя ноутбука. Если у вас старая модель ноутбука и на официальном сайте, нет новых драйверов для ОС Windows 10, лучше отказаться от установки драйвера на тачпад (вы можете установить драйвер для тачпада, который не совместим с ОС Windows 10, однако не известно, как он себя поведет). Либо, оставаться на ОС Windows 7.

The SYSTEM_THREAD_EXCEPTION_NOT_HANDLED is a STOP code of a blue screen of death (BSOD) error. You might typically see the blue screen as you start your PC, when launching a program like a game, or in the middle of a gaming session. It usually comes with a certain driver file name in SYS extension, such as nvlddmkm.sys, bcmwl63a.sys, ntfs.sys, atikmdag.sys, or dxgmms2.sys. In this guide, we will explain what this error actually means and how you can fix the problem.
Update: Recently, a lot of users have been seeing the “SYSTEM THREAD EXCEPTION NOT HANDLED” blue screen error when playing Fortnite or Valorant. It seems to be caused by a graphics card driver that doesn’t work compatibly with the games right now. To fix this, try to update your graphics card driver to see if there is already a hotfix for this problem.
What does the “SYSTEM THREAD EXCEPTION NOT HANDLED” blue screen error mean?
This blue screen STOP error in Windows 10 and 11 usually points to a driver problem. When a driver is broken, outdated, not installed properly, or messed with by malware, it can cause the BSOD error.
If a hardware part is failing or is already broken, it can also cause the blue screen error when you start up your PC. If the error only happens when you start a program, it might mean that the hardware’s driver doesn’t work compatibly with the program or is corrupted.

Updating the problem driver
There are several ways to update a device driver in Windows 10 and 11. The best way is to find and download the latest driver from your hardware’s manufacturer websites, like the Nvidia video driver from nvidia.com. This makes sure you get the latest driver for your device.
Since most users can’t boot into Windows to update any driver, you can force your Windows 10 or 11 to start in safe mode, skipping the blue screen. See: How to enter safe mode in Windows 11/10 if your Windows is corrupted.
When you’re in Windows 10 or 11 safe mode, follow these steps to update a device driver through Device Manager:
- Go to the start menu.
- Search for Device Manager and open it.
- Find the driver that caused the error in the blue screen.
- If the problem is with your graphics driver, in Device Manager, open Display adapters.
- Right-click on your main graphics card and choose Update driver.
- Click Next to let Windows 10 or 11 automatically search for and install the right driver for your video card.
Alternatively, you can choose Uninstall driver when you right-click on your device to uninstall its driver. If the driver is wrong or broken from the start, uninstalling it can help fix the “System Thread Exception Not Handled” issue. On the next restart, Windows will automatically find and install the best matched driver for that device from Microsoft’s driver repository.
You can also use another computer to manually download the driver installer from the device’s manufacturer website. Then, transfer the installer to an external storage like a USB flash drive and open it on your problem computer while it’s in Safe Mode.
About “SYSTEM THREAD EXCEPTION NOT HANDLED” Ntfs.sys or Dxgmms2.sys
If you’re getting an error with a SYS file that doesn’t relate to any of your hardware, it might be tied to your Windows system files.
If you see Ntfs.sys, for example, it could be because of missing or corrupted system files, or even disk errors on your Windows system drive. Running SFC, DISM, and chkdsk scans might help fix the issue. Check this guide here: “How to Startup Repair Windows 10/11 using Command Prompt” to learn how to use these tools if you can’t boot into Windows.
If you’re dealing with the blue screen error with Dxgmms2.sys error instead, try running Windows Update to update DirectX 12 in Windows 10 or 11 safe mode.
You turn on your PC, and instead of getting the usual welcome by Windows logo, you see a blue screen with the message ‘Your PC ran into a problem and needs to restart‘. When you look closely at the blue screen error information, you see SYSTEM_THREAD_EXCEPTION_NOT_HANDLED in front of the Stop Code info. It’s a classic case of BSOD (Blue Screen of Death) on Windows 10 /11.
What sets apart the ‘System thread exception not handled’ error from other BSOD errors is that this blue screen error may result from the malfunctioning or corruption of multiple drivers simultaneously. Moreover, it causes your PC to get stuck in a reboot loop that a normal reboot can’t resolve.
