It's normal sound.
award bios
1 Short: The system starts normally. Congratulations, there is nothing wrong with your machine.
2 Short: General error, please go to CMOS Setup and reset the incorrect options.
1 long and 1 short: There is an error in the memory or motherboard. Try to change the memory, if it still doesn't work, you have to replace the motherboard.
1 long and 2 short: The display or graphics card is wrong.
1 long and 3 short: The keyboard controller is wrong. Check the motherboard.
1 long 9 short: Motherboard flash RAM or EPROM error, BIOS corruption. Try changing the block of flash ram.
Constant ringing (long sound): The memory module is not plugged in tightly or is damaged. If it still doesn't work, you can only replace a memory module.
Ringing: The power supply and monitor are not properly connected to the graphics card. Check all the plugs.
Repeated, short ring: There is a problem with the power supply.
No sound and no display: There is a problem with the power supply.
ami bios
1 Short: The memory refresh failed. Replace the memory module.
2 Short: The memory ECC verification error is incorrect. Setting the memory option for ECC check to disabled in CMOS setup will solve the problem, but the most fundamental solution is to replace a piece of memory.
3. Short: The basic memory of the system (the first 64KB) failed to be checked. Change memory.
4 Short: The system clock is wrong.
5 Short: Processor (CPU) error.
6 Short: Keyboard controller error.
7 short: The real mode of the system is wrong and cannot be switched to protection mode.
8 Short: A memory error is displayed. If there is a problem with the display memory, try changing the graphics card.
9 Short: ROM BIOS check and error.
1 long and 3 short: memory error. If the memory is damaged, it can be replaced.
1 long and 8 short: A test error is displayed. The monitor cable is not plugged in properly or the graphics card is not plugged in properly.

Tips given by the BIOS test.
For example, the normal is the drip into the system.
For example, the mistake is drip-drip-drip or long-drip.

There is no sound of the computer when it is turned on, which means that the motherboard has not passed the self-test and cannot be started. Usually due to the oxidation of the gold finger of the memory or graphics card, resulting in poor contact between the memory and the memory slot, and the poor contact between the graphics card and the graphics card slot, resulting in the inability to boot or the black screen at boot.
You need to turn off the power, open the case, remove the memory and the discrete graphics card, use the eraser to align the gold finger of the memory (that is, the part with the copper sheet) on both sides and wipe it a few times, and then plug it back, the discrete graphics card is also handled in the same way, and then the chassis is installed.
Precautions for using a computer.
Laptop manufacturers use fans, heat pipes, large heat sinks, and heat vents to reduce the high temperatures that occur when using computers. At the same time, in order to save power and avoid noise, the laptop's fan does not work all the time, but only starts when the CPU reaches a certain temperature. If the laptop is placed on a soft object (such as a bed or sofa), it may block the heat dissipation holes, which may affect the heat dissipation effect of the computer, and may reduce the operation efficiency of the computer in the future, and may even cause a crash.
Press del on boot,The notebook is f2 general.,Go in and turn off the floppy drive (that.。
It is estimated that it is a hardware problem, and you may be able to find out where the problem hardware is by listening to whether the alarm tone is normal. You unplug the graphics card and wipe the gold finger with an eraser (on both sides).
The reason for the occurrence of Didi Di Di San:
When the computer is just turned on, it makes a didibi sound from the inside of the case, these sounds are emitted from the small speaker on the computer motherboard, and the BIOS detects the sound prompt when the fault is detected during the self-test, and each fault has a different length and short Didi sound. >>>More
You try to do one of the following two things, first: remove the graphics card and wipe the gold finger. Second: Discharge the motherboard (disconnect the motherboard cable for power, then remove the button battery, and connect the positive and negative poles of the button battery holder with metal for 5 seconds).
An important function of the motherboard BIOS is the POST power-on self-test program, after the microcomputer is connected to the power supply, the system will first check the main accessories such as the motherboard itself and the memory by the program, once the problem is found in the self-test, the system will give a prompt message or a whistle warning. For example, the specific meaning of the most common BIOS boot chirp is as follows for your reference: >>>More
