Dell Computer Fault Beep 3 Long 2 Short Message

1 short: the system starts normally.

2 Short: General error, please enter CMOS settings and reset incorrect options.

1 long, 1 short: memory or motherboard error. Try replacing the memory. If it doesn't work, we have to replace the motherboard.

1 Long 2 Short: There is something wrong with the monitor or graphics card.

1 Length 3 is short: keyboard controller error. Check the motherboard.

1 length 9 short: the motherboard FLASH RAM or PROM is wrong, and the BIOS is damaged. Try changing the flash memory.

Continuous ringing (long ringing): the memory stick is wrong or damaged. Replace the memory.

AMI BIOS

1 Short: Memory refresh failed. Replace the memory.

2 Short circuit: Memory ECC verification error. In CMOS settings, just set the memory option about ECC verification to disabled. But the most fundamental solution is to replace a memory.

3 Short: System basic memory detection failed. Change your memory.

4 Short: System clock error.

5 short: CPU error.

6 Short: Keyboard controller error.

7 Short: System real mode error, unable to switch to protection mode.

8 Short: Memory error is displayed. There is a problem with the display memory. Try replacing the video card.

9 short: BIOS chip verification error.

1 Long 3 Short: Memory corruption. Just replace it.

1 Long 8 Short: Test error is displayed. The monitor data cable is not inserted correctly, or the video card is not inserted correctly.
