BB is the sound of alarm.
You can judge what the problem is according to the length and frequency of the alarm.
The general meaning of the award BIOS ringtone is:
1 short: the system starts normally. This is what we hear every day, which also shows that there is nothing wrong with the machine.
2 Short: General error, please enter CMOS settings and reset incorrect options.
1long1short: Error in RAM or motherboard. Try to change your memory. If it still doesn't work, we will change the motherboard.
1 long 2 short: monitor or graphics card error.
1 Length 3 is short: keyboard controller error. Check the motherboard.
1 length 9 short: the Flash RAM or EPROM of the motherboard is wrong, and the BIOS is damaged. Try changing the flash memory.
Constant ringing (long sound): The memory module is not tightly inserted or damaged. Reinsert the memory stick. If it still doesn't work, you need to change a memory.
Non-stop ringing: the power supply and monitor are not connected to the graphics card. Check all plugs.
Repeated short tone: power problem.
No sound, no display: power problem.
The general meaning of AMI BIOS ringing is:
1. A short sound, memory refresh failed. The memory is badly damaged. I'm afraid I have to replace it.
2. Two short tones, memory parity error. You can enter CMOS settings and turn off the memory parity option, that is, set it to disabled. Generally speaking, however, the memory stick has parity, and the parity is turned on under the CMOS setting, which is beneficial to the stability of the microcomputer system.
3. After three short sounds, the system basic memory (1 64Kb) failed to be checked. Replace the memory.
4. Four short tones, system clock error. Repair or replace the motherboard.
5. Five short sounds, CPU error. But it is not necessarily the fault of the CPU itself. It is also possible that there is something wrong with the CPU socket or other places. If this CPU is normal on other motherboards, the fault must be the motherboard.
6. Six short tones, keyboard controller error. If the keyboard is not plugged in, it is very simple, just plug it in; If the keyboard connection is normal but there is an error prompt, try a good keyboard; Otherwise, there is something wrong with the keyboard control chip or related parts.
7. Seven short tones, system real mode error, unable to switch to protection mode. This is also the fault of the motherboard.
8. Eight short tones, indicating memory reading and writing errors. The memory module on the video card may be damaged. If the memory module is pluggable, just find out the bad chip to replace it, otherwise the graphics card needs to be repaired or replaced.
9. Nine short sounds, ROM BIOS check error. Try to change a good BIOS of the same type. If it proves that there is something wrong with the BIOS, you can try to recover it by rewriting or even hot plugging.
10. Ten short tones, register read/write error. Only the motherboard can be repaired or replaced.
1 1 .11 short tones, cache error.
12. If you can't hear the beep and see the screen display, first check whether the power supply is connected properly. Maintenance is often easy to neglect, and the test is started without connecting the motherboard power supply. Secondly, it depends on whether there are any missing components, such as CPU and memory chips. Similarly, unplug all the cards in question and try only the video card. Finally, find the jumper on the motherboard to clear the CMOS settings, clear the CMOS settings, and restore the BIOS to the factory state. If the monitor, graphics card, wiring are all right, and the CPU and memory are all right, after the above steps, the microcomputer still doesn't display or ring, so it can only be the problem of the motherboard.

See for yourself what type of motherboard it is and look for it accordingly.
