잘되던 PC 갑자기 전원이 들어오지 않는다면?

과 비슷 한 유형의 질문을 받았기에  비슷한 내용을 QA 형식으로 포스팅합니다.





Q 잘되던 PC가 작동이 되지않습니다.

부팅시 Debug Led에 아무런 포스팅 코드도 나타나지않고 작동이되지 않습니다
새벽에 벼락이 치던데 어떻게 된걸까요
?


A 메인보드에 전원을 인가후 작동을 시켰을떄 LED에 아무런 포스팅코드가 나타나지 않는다 단 기기들이 작동을한다면(CPU 쿨러 / 시스템 쿨러 등)

 먼저 바이오스 에러로 생각할수 있습니다. 이경우 동일 바이오스로 교체 하는 방법이있는데 대게는 AS 센터로 가는수 밖에없습니다.


기기들이 작동을 하지 않는다면 메인보드 쇼트일수도 있습니다. 쉽게는 벼락때문일수도 있지요. 흔히 메인보드가 사망했다고 하는경우입니다.
단 요즘에는 메인보드가 사망하기전에 파워서플라이에서 과전류를 막아주기도 하여 메인보드가 사망에 이르는 경우는 그리 많지않습니다.

파워서플라이의 작동여부(팬/다른 장치로 들어가는 부분 -4핀전원선->시스템 쿨러)를 확인해보시고 작동이 되지않는다면 파워 이상이입니다.


비슷한 경우 있으신분들 참고 되셨으면 합니다.

  1. 지난 여름 휴가때 잘 쓰던 컴퓨터가 재부팅후에 갑자기 안되더군요.
    전원을 넣었는데.. 팬만 돌고.. 아무반응이 없음.

    그래서.. 저는...
    컴퓨터의 모든 부품을 뜯었다가 다시 끼웠습니다. ㅎ ;

    결과. 잘 동작하더군요. ㅎ ; 뭐가 문제 였을까나?

    • Chan님 작동하신다니 다행이내요.^^
      경우의 수가 역시나 많은경우이내요.

      잘쓰던게 갑자기 리부팅후 않되었는데 부품 제장착후 잘되었다..

      저같은 경우에는 두가지 경험한적이있는데
      1. 장치 콘덴서중 한개이상이 이상증상
      -M/B 콘덴서 부분 하나가 배가 불러 물이 줄줄 흐르더군요 사용에는 시간을 둔뒤에 제부팅하니 사용은 가능했습니다만 부하가 높은작업을하면 여지없이 죽더군요.

      지금도 비슷한경우가 종종 일어난다고 생각하시면 즉시 M/B 콘덴서 부분을 확인하시는게 좋을것 같습니다.


      2. 쇼트로 인한 일시적 장애
      쇼트가 일어나면 일단 장치가 먹통이 되는데 다행이 죽지는 않고 렘슬롯쪽에 살짝 그을린 흔적이있더군요

      경우의 수가 워낙 많은게 PC 장애이다보니 ^^

      Chan님 즐거운 휴일 되셨으면 합니다
