Window 10 오류 코드 목록.txt 

문제로 인해 예기치 않게 PC가 종료되거나 다시 시작되는 경우 중지 오류("블루 스크린" 오류라고도 함)가 발생할 수 있습니다. 이러한 유형의 오류가 발생하면 PC를 켰을 때 화면에서 시작 메뉴 또는 작업 표시줄과 같은 항목을 볼 수 없습니다. 대신 PC에서 문제가 발생하여 다시 시작해야 한다는 메시지와 함께 블루 스크린이 표시될 수 있습니다.

블루 스크린 오류의 이유라도 알고 싶을 때 한번 찾아보세요.
윈도우 블루 스크린 오류 코드 목록에서Ctrl+F를 누르시고 오류코드를 입력하세요. 그리고 구글 번역을 하면 대충 이해는 할 수 있습니다.
