Know the BIOS beep code of Computer System


Hi, guys. How are you? I am fine. Today I am bringing you BIOS Beep Code of Your System. I will give you BIOS beep code by One by One BIOS Version. So let’s Start:

Standard Original IBM POST Error Codes

bios error code

  • 1 short beep System is OK.
  • 2 short beeps POST Error – error code shown on screen No beep Power supply or system board problem Continuous beep Power supply, system board, or keyboard problem Repeating short beeps Power supply or system board problem.
  • 1 long, 1 short beep System board problem.
  • 1 long, 2 short beeps Display adapter problem (MDA, CGA).
  • 1 long, 3 short beeps Display adapter problem (EGA).
  • 3 long beeps 3270 keyboard card.

AMI BIOS Beep Codes

1 Short Beep System OK.
2 Short Beeps Parity error in the first 64 KB of memory
3 Short Beeps Memory failure in the first 64 KB
4 Short Beeps Memory failure in the first 64 KB Operational of memory or Timer 1 on the motherboard is not functioning
5 Short Beeps The CPU on the motherboard generated an error
6 Short Beeps The keyboard controller may be bad. The BIOS cannot switch to protected mode
7 Short Beeps The CPU generated an exception interrupt
8 Short Beeps The system video adapter is either missing, or its memory is faulty
9 Short Beeps The ROM checksum value does not match the value encoded in the BIOS
10 Short Beeps The shutdown register for CMOS RAM failed
11 Short Beeps The external cache is faulty
1 Long, 3 Short Beeps Memory Problems
1 Long, 8 Short Beeps Video Card Problems
