Detailed explanation of BIOS alarms

BB is the alarm sound. You can determine the problem based on the alarm sound length and quantity.

The general meaning of award bios Bells is:
1 short: the system starts normally. This is what we can hear every day, and it also indicates that the machine has no problems.
2 short: A general error occurs. Enter CMOS Setup and reset the incorrect options.
1 long and 1 short: an error occurs in RAM or the motherboard. Try another memory. If it still doesn't work, you have to replace the motherboard.
1 long 2 short: Incorrect display or display card.
1 long 3 short: Incorrect keyboard controller. Check the motherboard.
1 long 9 short: The Flash RAM or EPROM on the motherboard is incorrect, and the BIOS is damaged. Try changing block Flash RAM.
Constant sound (long sound): the memory stick is not plugged in or damaged. Re-insert the memory stick. If it still does not work, only one memory will be replaced.
The power supply and display are not connected to the display card. Check all the plugs.
Duplicate short response: power supply problems.
No sound, no display: power supply problems.

The general meaning of an ami bios ring is:
1. In a short message, the memory refresh failed. Memory Corruption is serious. I'm afraid I have to replace the memory.
2. Two short voices, memory parity error. You can go to the CMOS settings and turn off the memory Parity option, that is, set it to Disabled. However, in general, the memory module has a parity check and enables the parity check in the CMOS settings, which is good for the stability of the microcomputer system.
3. The system basic memory (1st 64Kb) fails to be checked. Change the memory.
4. Four short voices, system clock error. Repair or replace the motherboard.
5. Five Short voices, CPU error. But it may not be all about the CPU itself, or it may be a problem with the CPU outlet or somewhere else. If the CPU is normal on another motherboard, it must be the motherboard.
6. the keyboard controller is incorrect with six short voices. If the keyboard is not plugged in, just do it. If the keyboard connection is normal but there is an error message, try another good keyboard; otherwise there is a problem with the keyboard control chip or related parts.
7. The system real-time mode is incorrect and cannot be switched to the protection mode. This is also the fault of the motherboard.
8. An error occurred while reading/writing the video. The storage chip on the video card may be damaged. If the storage is pluggable, you only need to find and replace the bad parts. Otherwise, the video card needs to be repaired or replaced.
9. An error occurred while checking the rom bios. Try changing the BIOS of the same type. If it proves that there is a problem with the BIOS, you can try to recover it by rewriting or even hot swapping.
10. Register read/write Errors for 10 short voices. You can only repair or replace the motherboard.
11. An error occurred while caching.
12. If you cannot hear the beep sound or see the screen display, you should first check whether the power supply is properly connected. during maintenance, it is often easy to neglect. If you do not connect the power supply to the motherboard, the system will start the test. Next, let's see if there are few plug-ins, such as CPU and memory. Once again, unplug all the plug-in cards in question and leave the display card for a try. Finally, find the clear CMOS patch cord on the motherboard, clear the CMOS settings, and let the BIOS return to the factory status. If there is no problem with the display, display card, and connection, and there is no problem with the CPU and memory, after the above steps, the microcomputer still does not display or sound a bell when it is started, the problem can only be caused by the motherboard.
