Why does the computer have a sizzle sound?

This is the sound of the hard drive running yes.

Ordinary hard drives will have sound, and the way it works is a miniature version of ancient record players, and it's normal to hear subtle sounds if you put your ears to the case, and solid-state drives (rarely used except for game enthusiasts or special needs for high performance) are silent; Generally, the hard disk is easily damaged under the sudden power failure of the computer, abnormal shutdown or vibration, so the buzzing is likely to be broken.

Hard disks. sounds. Laptop mechanical hard disk sometimes has a similar sound when working, but not all the time, if there is a continuous and loud sound, then you should go to the repair point to see if there is a problem with the hard disk.

Noise from the horn. Check whether there are strong magnetic things around, and sometimes don't hit ** in front of the computer, there will be a sizzling sound.

Fan sounds. If the fan touches the internal wiring, it is prone to this sound, or it touches the heat dissipation tin foil.

This is what it usually sounds like. In this case, if you don't know much about the computer, don't disassemble it privately, because to disassemble the radiator, you basically have to disassemble the C side of the notebook, and it is easy to break if there is no foundation.

When the computer is turned on, the reason why there is a squeaky sound is the sound that occurs when the computer is self-checking, and if it does not affect the normal use, it should be a normal sound.

If there is a sizzling sound in the computer, it should be caused by a short circuit in the computer, or a problem with the bellows of the computer and the fan is not running well.

Is there a buzzing noise in the computer sound?

1. In this case, first of all, it may be because the interface of the audio cable or the cable itself is faulty, so it will lead to computer sound entrainment noise. 2. It may also be because the hardware of the speaker itself is faulty, and the computer sound will also carry noise. 3. It may also be because the computer is running for a long time, if the ventilation is not smooth, it may lead to the computer sound entrainment noise.

4. It may also be because the computer fan is relatively loud, so this situation will also occur.

Suggested workaround:

1. When the interface of the computer's audio cable or the cable itself fails, you can contact professional maintenance personnel to replace the audio cable to solve the problem of computer sound entrainment noise.

2. When the hardware of the speaker itself fails, the computer speaker can be replaced to solve the problem.

3. It is not recommended to pile up some sundries around the computer host, which is likely to affect the ventilation of the computer, and the ventilation is not good, or it is possible that there is too much dust in the motherboard of the computer, and the dust can be cleaned to solve the problem.

4. When the noise caused by the failure of the fan, the fan can be replaced or the dust of the fan can be cleaned up, so as to solve the problem of computer sound entrainment noise.

The noise of computer sound sizzling and the solutions are as follows:

1. The first is to listen to the sound to identify the noise source, if you hear a kind of "empty hum", it is generally caused by the resonance of the fan rotation and the chassis, because the chassis is made of a thin layer of iron, and the inside is relatively empty, which can amplify the noise, so how to solve it? For this kind of problem, you only need to loosen the covers on both sides of the chassis so that the covers do not fit completely with the frame, and you will find that the tighter the screws of the cover plates, the louder the noise, and the noise will disappear after the screws are loosened.

2. If you hear an obvious fan rotation sound, it means that your fan is short of oil, because if it rotates for a long time, the lubricating oil will be exhausted sooner or later.

3. If you hear a noise similar to "vibrato", then you need to check whether the discrete graphics card is fixed, whether the screws fixed between the motherboard and the chassis are loose, whether the screws of the power supply are loose, and if the case cooling fan is installed, check whether the chassis cooling fan is loose.

4. Tips to prevent chassis noise, if your chassis does not have screw rubber gaskets, we can use waste mouse pads, cut them into gaskets, and directly pad a small piece of screws in contact with the chassis, which can effectively reduce noise.

Tips for maintaining your computer

Normal shutdown. This point is the point that everyone is most likely to ignore, open a lot of background programs in the office, save trouble when shutting down, and force shutdown, which will affect the normal reading and writing of the hardware, resulting in information loss, and in serious cases, it will cause permanent damage to the hardware! It is also necessary to avoid sudden power failure, which will cause irreversible damage.

Maintenance of LCD screens.

The computer LCD screen is also very expensive, it is recommended to turn on the power-saving mode, the computer will automatically turn off the screen when not in use, which can not only save power, but also extend the life of the LCD screen. At the same time, you can apply the LCD screen film to avoid scratches, for patients with obsessive-compulsive disorder, I don't know if I will change the screen directly when I see a little scratch, and at the same time, it is recommended to use a special cleaner for daily wiping and cleaning.

The main reasons why computers make sizzling sounds are as follows:

1. The computer's fans (such as CPU fans, graphics card fans, power supply fans, etc.) may have slight contact with nearby objects, resulting in sizzling sounds, and the most likely is the wires.

2. If the hard disk track and the head are slightly touched, this is more dangerous, if the sound is so frequent, the hard disk is almost out of order.

3. The sound of current is mostly a virtual connection of a certain wire or a virtual welding of a solder joint, and the current flowing through it is not small, which causes the sound of current.

A computer is a machine that uses electronic principles to process data according to a series of instructions. A computer can be divided into two parts: a software system and a hardware system.

The first computer was the ENIAC general-purpose electronic computer born at the University of Pennsylvania in the United States on February 15, 1946.

People refer to computers without any software installed as bare metal. With the development of science and technology, some new types of computers have emerged: biological computers, photonic computers, quantum computers, etc. On May 24, 1954, the transistor electronic computer was born.

The first generation of computers had a very limited variety of input and output devices. The usual input device is a card reader that punches cards, which is used to import instructions and data into memory; The output device used to store the results is typically tape. With the advancement of science and technology, the abundance of input and output devices has been improved.

Take the personal computer as an example: the keyboard and mouse are the main tools for the user to input information directly into the computer, while the monitor, printer, megaphone, and headset return the processing results. In addition, there are many input devices that can be used to accept other different kinds of information, such as digital cameras that can input images.

Among the I/O devices, there are two categories that are worth noting: the first is secondary storage devices such as hard disks, optical discs, or other devices that are slow but have a high capacity. The second is computer network access devices, through which the direct data transfer between computers greatly enhances the value of computers.

Today, the Internet has enabled tens of millions of computers to transmit various types of data to each other.

There are generally three situations in which a sizzling sound is made:

1. The mains voltage is too high, or the power supply is small, and the load is too heavy. If the mains voltage is too high, another voltage regulator can be added; If the hardware power consumption in the host is large, this power supply can bear it, and change it to a power supply with high power.

2. The inductance coil and transformer in the power supply will not affect the use of the inductor noise caused by poor impregnation or poor design, and there is no good way to solve it except for replacement.

3. The inferior capacitor in the power supply, or the pulp capacitor will produce a sizzling sound after being energized, and replace the problematic capacitor.

Electronic computer, commonly known as computer, is a modern electronic computer machine used for high-speed calculation, which can carry out numerical calculations and logical calculations, have storage and memory functions, and can run according to programs to automatically and high-speed process massive data. It consists of a hardware system and a software system, and a computer without any software installed is called bare metal. Computers are used as control systems for a variety of industrial and consumer equipment, including simple purpose-built equipment, industrial equipment, and general-purpose equipment.

The inventor of the computer, Johann von Neumann. The computer is one of the most advanced scientific and technological inventions of the 20th century, which has had an extremely important impact on human production and social activities, and has developed rapidly with strong vitality. The application of computers is becoming more and more common in China, after the reform and opening up, the number of computer users in China has been rising, and the level of application has been continuously improved, especially in the fields of the Internet, communications, and many other fields, and has achieved good results.
