Unknown hard error windows 10 как исправить

Способ 1: Восстановление системных файлов

Сообщение об ошибке «Unknown Hard Error» зачастую появляется непосредственно сразу после запуска операционной системы. Оно может свидетельствовать о повреждении системных файлов. Причиной этому является некорректные действия пользователя или воздействие вредоносных программ.

Чтобы устранить неисправность, необходимо произвести процедуру восстановления системных файлов. Для этих целей в Windows 10 предустановлена специальная утилита, которая в автоматическом режиме анализирует состояние данных на диске «C:\» и при обнаружении проблемных участков производит их восстановление. Ее запуск выполняется через «Командную строку», запущенную от имени администратора. Вам потребуется ввести всего один запрос. Подробнее об этом рассказывается в другой статье на нашем сайте, доступной по ссылке ниже.

Способ 2: Проверка диска на наличие ошибок файловой системы

Вне зависимости от результата проверки системного диска специальной утилитой, после необходимо запустить другое приложение, которое выявляет ошибки иного типа. В этом случае можно воспользоваться как предустановленными в операционной системе инструментами, так и решениями от сторонних разработчиков. На нашем сайте есть отдельная статья, в которой подробно описывается процесс диагностики накопителя. Рекомендуем с ней ознакомиться, чтобы определить наиболее подходящий способ выполнения поставленной задачи.

Способ 3: Отключение автозагрузки сторонних приложений

Ошибка «Unknown Hard Error» может появляться в Windows 10 из-за негативного влияния программного обеспечения, которое запускается параллельно с операционной системой. В этом случае необходимо отключить автозагрузку всех сторонних приложений и перезапустить компьютер. Процедуру эту можно выполнить несколькими способами, каждый из которых описан в отдельном материале на нашем сайте. Воспользуйтесь ссылкой ниже, чтобы ознакомиться с ним. Ваша задача на этом этапе выполнения инструкции — убрать все приложения из автозагрузки.

Если после перезагрузки компьютера ошибка «Unknown Hard Error» не появляется, значит причина, заключалась в негативном влиянии стороннего программного обеспечения. Его необходимо найти и удалить. Чтобы не проверять каждое установленное в операционной системе приложение, откройте специальное меню со списком программ, добавленных в автозагрузку. Для этого запустите «Диспетчер задач». Сделать это можно несколькими способами, например, воспользовавшись поиском по системе. Установите курсор в соответствующее поле на панели задач и введите запрос «Диспетчер задач», после чего в результатах кликните левой кнопкой мыши по одноименному приложению.

В появившемся окне проследуйте во вкладку «Автозагрузка». Именно там будет находиться весь список приложений, добавленных в автозапуск, включая те, которые были вами отключены.

Чтобы обнаружить программу, которая вызывает ошибку «Unknown Hard Error», поочередно запускайте каждое приложение из списка автозагрузки. Когда будет найдено проблемное, удалите его полностью с компьютера. Важно это сделать правильно, иначе остаточные файлы могут продолжить конфликтовать с компонентами Windows 10 и ошибка никуда не исчезнет. На нашем сайте есть отдельная статья, в которой подробно рассказывается о том, как деинсталлировать программное обеспечение. При необходимости ознакомьтесь с ней, перейдя по ссылке ниже.

Способ 4: Обновление драйверов оборудования

Ошибка «Unknown Hard Error» может появляться в операционной системе из-за некорректной работы драйверов. Чтобы исключить этот фактор, необходимо проверить наличие обновлений данного программного обеспечения и при обнаружении новых версий инсталлировать их в Windows 10. Эта процедура может быть выполнена как вручную, подразумевая применение штатных инструментов операционной системы, так и с помощью сторонних приложений, которые в автоматическом режиме производят все действия. Подробнее об этом вы можете узнать в другом материале на нашем сайте.

Способ 5: Проверка компьютера на наличие вирусов

Даже если предыдущие методы помогли вам в устранении ошибки «Unknown Hard Error», после их выполнения все равно рекомендуется проверить компьютер на наличие вирусов. Если они присутствуют, это гарантирует повторное появление проблемы. Воспользуйтесь специальным приложением для поиска и удаления вредоносного кода из операционной системы. Вы можете применить как штатное средство, так и разработанное сторонней компанией.

Solved Answer

Unknown Hard Error is an unpleasant pop-up that might show up on your screen at any time. This Windows 10^[1] alert might show up when you are playing an online game, using various programs, closing or opening apps or doing other activities on your PC. The error stops your activities due to a bunch of different problems:

• corruption of system files,

If some of these problems occur, users receive a pop-up alert which often identifies the process or file’s location that triggered the error:

The Unknown Hard Error causes a real havoc on the system. As pointed out by people who encountered it, the error turns the screen black, freezes the taskbar, and can make all desktop icons gone. Additionally, some users face various Blue Screen of Death (BSOD) errors.
