The system beeps after the computer is installed?

I suggest you go to the official computer maintenance department as soon as possible. This should be a hardware problem, and you need to check it before you know it.

The beeps have a certain meaning, and you can find out the problem if you listen carefully.

1. AMI BIOS

1 Short beep—Memory refresh failed

2 Short beep—Memory ECC verification error

3 Short beep— —System basic memory (1st 64K) check failed

4 short beeps-system clock error

5 short beeps-central processing unit (CPU) error

6 short beeps - keyboard controller error

7 short beeps - system real mode error, cannot switch to protected mode

8 short beeps - display memory error (display memory may be corrupted) Damaged)

9 short beeps - ROM BIOS checksum error

1 long 3 short beeps - memory error (memory is damaged, please replace)

1 long 8 short beeps Ringing - display test error (monitor data cable is loose or the graphics card is not inserted firmly)

2. Award BIOS

1 short - the system starts normally

2 short - —General error, please enter CMOS SETUP to reset the incorrect option

1 long 1 short - RAM or motherboard error

1 long 2 short - display error (monitor or display card)

1 long 3 short - keyboard controller error

1 long 9 short - motherboard FlashRAM or EPROM error (BIOS damage)

keeps beeping (long beep) ——The memory is not inserted firmly or is damaged

Keeps ringing——The power supply, monitor and graphics card are not connected properly

Repeated short beeping——Power supply failure

No sound No display - power failure

3. Phoenix BIOS

1 short - the system starts normally

3 short - the system power-on self-test initialization (POST) failed

1 short 1 short 2 short - motherboard error (the motherboard is damaged, please replace)

1 short 1 short 3 short - the motherboard battery is dead or the CMOS is damaged

1 Short 1 short 4 short - ROM BIOS verification error

1 short 2 short 1 short - there is a problem with the system real-time clock

1 short 2 short 2 short - DMA channel initialization failed

1 short 2 short 3 short - DMA channel page register error

1 short 3 short 1 short - memory channel refresh error (the problem scope is all memory)

1 short 3 short 2 short - basic memory error (memory damage or RAS setting error)

1 short 3 short 3 short - basic memory error (most likely the memory on the DIMM slot is damaged)

1 short 4 short 1 short——An address error in the basic memory

1 short 4 short 2 short——The system basic memory (the first 64K) has a parity error

1 short 4 short 3 short - EISA bus sequencer error

1 short 4 short 4 short - EISA NMI port error

2 short 1 short 1 short - system basic memory ( The first 64K) check failed

3 short 1 short 1 short - the first DMA controller or register error

3 short 1 short 2 short - the second DMA controller Or register error

3 short 1 short 3 short - main interrupt processing register error

3 short 1 short 4 short - deputy interrupt processing register error

3 short 2 Short 4 short - there is a problem with the keyboard clock, reset it to Not installed in CMOS to skip POST

3 short 3 short 4 short - the display card RAM is wrong or there is no RAM, it is not a fatal error

3 short 4 short 2 short——The monitor data cable is loose or the display card is not inserted firmly or the display card is damaged

3 short 4 short 3 short——The ROM BIOS of the display card is not found

4 short 2 short 1 short - system real-time clock error

4 short 2 short 3 short - the Gate A20 switch in the keyboard controller (8042) is wrong, the BIOS cannot switch to protection mode

4 short 2 short 4 short - protected mode interrupt error

4 short 3 short 1 short - memory error (memory corruption or RAS setting error)

4 short 3 short 3 short - system second clock error

4 short 3 short 4 short - real-time clock error

4 short 4 short 1 short - serial port (COM port, mouse Port) fault

4 short 4 short 2 short - Parallel port (LPT port, print port) error

4 short 4 short 3 short - Math coprocessor (8087, 80287, 80387, 80487) Error
