Beep Codes : Detecting computer hardware failure

Beeps are your computer’s way of letting you know what’s going on when the video signal is not working. These codes are built in to the BIOS of the PC. There is no official standard for these codes due to the many brands of BIOS that are out there.

Common computer problem with beep code designation:

1 long beep, 2 short beeps :Failure in video system: a checksum error was encountered in video BIOS ROM, or a horizontal retrace failure has been encountered.

1 long, 3 short :Failure in video system: the video DAC, the monitor detection procedure or the video RAM has failed.

2 short :POST has failed, caused by a failure of one of the hardware tests.

These are the common AMI Bios Beep Codes:

1 short DRAM refresh failure
2 short Parity circuit failure
3 short Base 64K RAM failure
4 short System timer failure
5 short Process failure
6 short Keyboard controller Gate A20 error
7 short Virtual mode exception error
8 short Display memory Read/Write test failure
9 short ROM BIOS checksum failure
10 short CMOS shutdown Read/Write error
11 short Cache Memory error
1 long, 3 short Conventional/Extended memory failure
1 long, 8 short Display/Retrace test failed

These are the common IBM Bios Beep Codes:

No Beeps - No Power, Loose Card, or Short.
1 Short Beep Normal - POST, computer is ok.
