며칠전에 모니터 인식이 안되서 헤메다가 외장글픽 금속단자부분 지우개질해서 모니터 인식되고 잘지내다가 오늘 또 안되더라구요.. 그래서 저번에 고친 기억살려서 본체뜯어서 외장글픽 지우개질 하고 이왕에 cpu쿨러 서멀도 재도포도 하고 컴을 켰는데 모니터가 계속 신호없음만 뜨드라구요 그래서 다른방법 또있나해서 램카드도 지우개질해보고 키는데 컴터는 켜지는대 부팅중에 꺼지는데 이걸 계속 반복하는거에요 이게또 왜그러나 또또 검색.. 결론은 램카드 제대로 부착을 안해서 -_- 우여곡절 끝에 본체는 잘돌아갑니다 근데 모니터신호없음은 그대로 하.. 
게다가 이번엔 키보드 인식x 마우스 밑에led불은 들어오는데 마우스 커서 속도조절버튼? led는 안들어오고 랜 led도 불빛이 안들어오는데 일이점점 커지는거 같습니다 더이상의 방법은 또 없을가요? ㅜㅜ
