When this computer starts the self test, it beeps twice, what is going on, and how to deal with it

If the two tones are short, it proves that the hardware failure of the system peripherals has been detected.

For example, hard disks, keyboards, graphics cards, sound cards, network cards, etc., if there are two long beeps, it should be caused by memory failure.

In short, it proves that there is something wrong with the computer hardware, you can first clean up some dust, unplug and unplug it to see if there is a loose board or loose wire, etc.

Some motherboards have a short ring, which means that the self-test has passed. Two short tones represent a coms error. Two tones indicate a memory problem.

It's best to tell me about your motherboard model. I'll help you find out.

The sound of the drop is a prompt to turn on the power, mine only beeps once.

According to the length and number of alarm sounds, the problem can be judged, and the meaning of Award BIOS alarm sound is:

One short: The system is normal, and we can really hear it every day.

Two short: general error, you can go to CMOS setup to reset it.

One long and one short: There is an error with the RAM or motherboard. Replace the memory module, if not, only replace the motherboard.

One long and two short: The monitor or graphics card is wrong.

One long and three short: The keyboard controller is wrong. Check the motherboard.

One long and nine short: Motherboard falsh RAM or EPROM error, BIOS corruption. Try a different block of flash ram.

Constant ringing (long sound): The memory module is not plugged in tightly or is damaged.

Non-stop ringing: The power supply and monitor are not properly connected to the graphics card.

Repeated short rings or no sound without display: power supply problems.

1. If there is an alarm sound when the computer is turned on, there must be a problem with the computer hardware, and then look at whether the light of the keyboard is on, you can press the upper and lower case keys on the keyboard. The light is on to indicate a problem with the graphics card or other hardware failure. 2. If the keyboard light does not light up, it may be a problem with the memory, CPU and motherboard.

Suggested treatment: 1. If the keyboard light is not on, it is recommended to use an eraser to wipe the memory module, and then check whether the gold finger of the memory module has any burn marks. It is recommended to replace the lower slot.

2. It is recommended to check the capacitors and resistors on the motherboard, see if the capacitors are bulging, whether there is any burning smell on the motherboard, etc., and then clean up the dust on the motherboard. 3. You can remove the CPU fan, turn on the power again, and test whether the CPU has a temperature change by hand, then the CPU is not working, or because the motherboard is broken, maybe the CPU is not plugged in well, it is recommended to re-plug it for the power supply problem, even if the power supply is powered on, but it can not let the motherboard work normally, it is recommended to replace the power supply to try. 5. If the display is loose or oxidized, the keyboard light will be on.

If the screen does not display, wipe the gold finger of the graphics card with an eraser, and then check whether the capacitors on the graphics card are bulging.

The computer won't boot and makes a dripping sound is usually caused by a hardware failure. Specific problems involve different computer models and configurations, and some common problems and solutions:

1.Memory Failure:Sometimes a computer makes a beeping sound when it starts up or runs, usually due to a core-excited memory failure.

You can follow the computer hardware repair specifications, remove and reinsert the memory module, or replace it with a new memory for testing.

2.Memory incompatible:If the computer has a DiDi sound after upgrading the memory, it is likely that the new memory is incompatible with the original memory.

Consider removing the new memory and replacing it with new memory that is compatible with the original memory.

3.Hard drive failure:Another possible cause is a hard drive failure.

In the case that the computer does not boot up, check whether the hard disk is recognized, and answer whether the hard disk can read data normally, etc., if there is a problem with the hard disk, it may also cause the computer to have a drip sound. It is recommended to replace the hard drive after backing up your important data.

4.Graphics card failure:If the sound emitted by the computer is accompanied by a black screen or error message, it is most likely caused by a malfunctioning graphics card. Try using the repair tools provided by the graphics card manufacturer or replacing it with a new one.

Note:When dealing with computer malfunctions, you should follow the computer maintenance specifications and pay attention to safe operation to avoid damage to the computer or personal injury. If you are inexperienced or unsure how to deal with it, it is advisable to seek help and support from a professional technician.

At the same time, in order to avoid computer failures, it is recommended to carry out regular system and cleaning hardware maintenance, and avoid malware and virus infection.

The sound is the alarm sound of the boot BIOS self-test. You look at what brand of board it is, and then you're looking for the meaning of the BIOS self-test sound, and you can compare it.

Generally, it is the self-test of the host that is okay and normal.

Didi is the sound of the computer booting up self-test, and it's not normal if there is no one.

There are many reasons, how can I say this...

This is the sound that the hard drive pointer makes when it reads the hard drive. Because the hard disk of the notebook is very close to the reading pin, it causes the phenomenon that the hard disk pointer and the hard disk are still in contact with each other after the notebook has experienced a strong vibration, resulting in the friction sound of the hard disk turning when the boot is turned on. In this case, it is still necessary to repair it.

If the memory is in poor contact, unplug the memory, clean the gold finger with an eraser, and then reinsert it back. (Be careful to note the direction of placement first, don't pretend to be reversed).

The inability to turn on the computer after making a beeping sound is a memory problem. Plug it back in.

If it can be turned on, it means that there is a problem with your system, restore it or reinstall it, and it is estimated that there is a problem with the system after your repair.
