Как запустить средство проверки памяти в Windows 10 и предыдущих версиях системы
В случае, если операционная система запускается, вход в неё и работа возможны, вы можете использовать один из следующих вариантов запуска средства проверки памяти:
- Найти нужный пункт в разделе «Средства администрирования Windows» меню «Пуск».
- Нажать клавиши Win+R на клавиатуре, ввести mdsched.exe и нажать Enter.
- Открыть панель управления, выбрать пункт «Администрирование» и запустить «Средство проверки памяти Windows».
- Использовать поиск в панели задач Windows 10, начав вводить «Средство проверки памяти». Или встроенные средства поиска в предыдущих версиях ОС.
- Вручную запустить файл C:\Windows\System32\MdSched.exe
Если же ситуация осложняется тем, что Windows не запускается, вход в неё невозможен, либо сразу после него происходят сбои, можно использовать следующие способы запуска средства диагностики оперативной памяти:
- Загрузить компьютер или ноутбук с загрузочной флешки с Windows 10 или другой версией Windows, можно и с загрузочного диска. На экране программы установки нажать клавиши Shift+F10 (Shift+Fn+F10 на некоторых ноутбуках), ввести mdsexe в открывшейся командной строке и нажать Enter. После выбора в утилите проверки пункта «Выполнить перезагрузку и проверку», загружайте компьютер не с флешки, а с обычного загрузочного HDD или SSD.
- Средство проверки памяти можно запустить из среды восстановления Windows 10 — нажав кнопку «Дополнительные параметры» на синем экране с ошибкой или, находясь на экране блокировки Windows 10 (с выбором имени пользователя) нажать по изображенной справа внизу кнопке «Питания», а затем, удерживая Shift, нажать «Перезагрузка». В среде восстановления выбираем «Поиск и устранение неисправностей» — «Дополнительные параметры» — «Командная строка». А в ней, как и в предыдущем случае используем команду mdsched.exe.
- Если у вас есть подготовленный диск восстановления Windows, запуск можно осуществить, загрузившись с него.
Использование средства проверки памяти Windows и просмотр результатов
После запуска средства проверки памяти вам будет предложено перезагрузить компьютер, после согласия, процесс будет выглядеть следующим образом:
- Начнётся проверка оперативной памяти, которая может занять продолжительное время. Может показаться, что средство диагностики зависло: на всякий случай подождите в такой ситуации 5-10 минут. Если же действительно произошло зависание, не исключено что есть проблемы с оборудованием, вероятно — с оперативной памятью, но не обязательно.
- Если в ходе проверки нажать клавишу F1 (или Fn+F1, если F1 не срабатывает), вы попадёте в настройки средства диагностики памяти Windows. Здесь можно выбрать набор тестов (по умолчанию — обычный), использование кэша, и число проходов. Переключение между разделами настроек выполняется клавишей Tab, изменение параметров — стрелками и вводом цифр (для числа проходов), применение параметров — клавишей F10. После изменения настроек тест перезапускается.
- В ходе проверки вы будете видеть информацию вида «Неполадки пока не обнаружены» или «Были обнаружены проблемы оборудования».
После завершения проверки компьютер будет автоматически перезагружен. Дальнейшие шаги — просмотр результатов.
- После перезагрузки в случае Windows 10 вы можете увидеть уведомление в области уведомлений, сообщающее о результате проверки памяти. Но оно отображается не всегда.
- Можно зайти в просмотр событий, для этого нажимаем Win+R, вводим eventvwr.msc и нажимаем Enter. Там открываем раздел «Журналы Windows» — «Система», находим пункты, где в столбце «Источник» указано MemoryDiagnostics-Results и просматриваем результаты.
Учитывайте, что ошибки, «вылеты», синие экраны и зависания не всегда связаны с проблемами оперативной памяти: если средство диагностики показывает, что всё в порядке, есть и иные возможные причины: отключенный файл подкачки, проблемы с HDD или SSD (или с их подключением, например — неисправный кабель), сторонние антивирусы или, наоборот, вредоносные программы, неправильная работа драйверов оборудования.
Что делать, если были обнаружены проблемы оборудования в средстве диагностики памяти
К сожалению, средство диагностики не сообщает о том, какие именно проблемы были обнаружены в ходе проверки, а лишь рекомендует обратиться к производителю оборудования. Что можно сделать:
- Отключить любые опции ускорения памяти (изменение частоты, таймингов и другие) при наличии соответствующих опций в БИОС или ПО производителя материнской платы или ноутбука.
- Попробовать проверить планки памяти по одной, в других слотах на материнской плате для того, чтобы выяснить, появляются ли проблемы только с одним конкретным модулем памяти или в одном конкретном разъеме.
- Использовать другие утилиты для проверки оперативной памяти при необходимости.
- Прочитать документацию к материнской плате ПК — возможно, это какая-то несовместимость с памятью с конкретными характеристиками (если вы недавно добавили новые модули памяти или только что самостоятельно собрали компьютер).
- Иногда может помочь обновление БИОС.

Windows Server 2019
The “Windows Memory Diagnostic” that comes standard with Windows Server 2019 is application software that allows you to check if there are any abnormalities in the memory. If the number of unintended restarts, sudden blue screens, and other errors that occur when using the terminal you are using increases, it is possible that there is a problem with the OS, disk, or memory, but there are cases where memory is the cause. It is often seen. * The resource handling method differs depending on the event ID output to the event viewer.
If there is a possibility of memory failure by judging the event ID / error message in the event viewer, we recommend “Windows Memory Diagnostic”, which is a standard Windows function. This time, we will explain how to check the log in the event viewer while executing the Windows Memory Diagnostic using Windows Server 2019.
