메인보드 BIOS 비프음 확인

AMI BIOS signals (American Megatrends Inc)

AMI BIOS 신호(또는 비프음 코드)는 아래와 같습니다. 그러나 이러한 유형의 BIOS를 사용하여 컴퓨터를 생산하는 다양한 제조업체로 인해 경고음 코드가 다를 수 있습니다.

AWARD BIOS signals

아래에는 AWARD BIOS 신호(비프음 코드)가 나열되어 있습니다. 이전의 경우와 마찬가지로 경고음 코드는 이러한 유형의 BIOS로 컴퓨터를 생산하는 다양한 제조업체로 인해 다를 수 있습니다.

사운드 신호(비프음 코드)설명

1 long beep, 2 short beeps	Indicates a video error has occurred and the BIOS cannot initialize the video screen to display any additional information. (Graphics card not found, or VRAM error)
1 long beep, 3 short beeps	Video card not detected (reseat video card) or bad video card (Depending on the BIOS version, this beep code may indicate either a graphics card error or a keyboard error)
Endlessly repeated signal	RAM problem.
Repeated frequent beeps while the computer is working	Overheating processor (CPU)
Repeated beeps, frequent and seldom	Issue with the processor (CPU), possibly damaged
