My computer is always loud, what should I do, who can help me, remember to have a bonus

What kind of sound is it? If it is an intermittent "click" sound (the sound is soft), it may be the sound of the hard disk reading, and you can't do anything about it, except for the backup of important files, you can ignore it. The optical drive sometimes emits sound, but there is no sound when the optical drive is not working.

After turning on the machine, there is a "whirring" wind sound in the case, which is the sound of the fan working normally. If it is a continuous "roar" like a motor or a chainsaw, it is the sound of dust accumulation by the fan or the lack of oil on the rotating shaft, and it is most likely that it will sound for a while when the machine is turned on. Workaround:

1) Brush and brush with some oil; (2) Replace it with a new one. If you are not afraid of trouble, the former is both economical and practical. You can use a small brush or a large oil brush to blow while brushing (it is best to have a "leather tiger" for blowing soot, or you can use a hair dryer to hit the cold air gear, or even use a pump to install a "gas needle" for playing basketball); To apply oil, uncover the circular covering film in the middle of the fan, let the shaft be exposed, and drip a little high-grade lubricating oil (car lubricating oil, sewing machine oil, and transformer oil are fine, but do not use cooking oil, because the cooking oil will be sticky for a long time and affect the operation of the fan), and then cover the film.

Sometimes not all of them are ringing, how can you tell which fan is ringing? You can take a chopstick, open the case to turn on the power, put one end of the chopsticks on the board with a fan, and the other end on the face, feel a significant vibration, and the vibration disappears with the "roar". After brushing and oiling, the problem could not be solved, so I had to change to a new fan.

Sometimes a loose screw will make a vibrating sound, if the above problems are ruled out, then check the screw again.

Symptomatic method: Just knock on the chassis when it rings.

How to cure the root cause: The sound is due to the loose screws in some places in the chassis, check it carefully and then unscrew it out.

The most common situation: CPU fan dust is too thick, fan bearings aging caused by the computer host loud At present, most CPU coolers are equipped with fans to achieve the purpose of rapid heat dissipation. If the computer is used for a long time, a lot of dust will accumulate on the CPU cooling fan, which will hinder the normal rotation of the fan and produce noise.

You just need to clean up the dust. But sometimes even if you clean the dust off the CPU fan, there will still be noise. This is because the bearing of the CPU fan is aging or lack of oil and dry, and there is a gap between the bearings that causes the sound of colliding back and forth when rotating, in this case, you can drop a few drops of sewing oil into the fan bearing, if it still doesn't work, you can only replace the fan, and the ** of the CPU fan is generally about 15 to 50 yuan.

The power supply fan is dusty or the computer host is loud due to aging The power supply is also equipped with a fan for heat dissipation, so it will accumulate dust or age after a long time. Since the power supply fans are all encapsulated inside the power supply, it is more troublesome to clean up the dust of the power supply fan. It is best to blow the dust out with a special hair dryer for computer maintenance, if not, the hair dryer at home can also be replaced, but the temperature of the wind cannot be overheated, it is best to use cold air.

Friends with hands-on ability can also disassemble the power supply fan (rookies don't try it) to clean it.

Most graphics cards are also equipped with cooling fans (some directly use heat sinks, no fans) The cleaning method is the same as above, and it is recommended to replace the new fan directly.

4. The computer host is loud due to the aging of the hard disk The hard disk will also age after a long time and make a "pimple, pimple" sound, but the sound is not very loud. At present, there is no good solution, I can only endure it, hehe. If you can't stand it, you have to replace it with a new hard drive.

When the host is turned on, the sound is relatively loud, but it is normal to enter the system. Reasons and solutions: This situation is generally caused by the graphics card fan, now the speed of many graphics card fans can be controlled by the software, you just turned on the system because there is no loading driver, so the fan speed is the default, when the system is controlled by the software, the speed will automatically decrease in the idle state, so the sound is smaller.

If that's the case, you can leave it alone. If you exclude the situation mentioned above and it is in winter, then it may be because the temperature is too low, the fan lubricating oil is a little solidified and does not melt, and the fan is running, and the lubricating oil is not so loud.

The loud noise of the computer when it is just turned on is generally the cause of the fan. Due to the lack of oil and dryness, the fan starts with a large torque, and the noise is large, and the torque is small after the normal speed of the acorn celery calendar, and the noise is reduced. If the noise is too loud, the CPU fan, graphics card fan, or power supply fan in your computer needs to be refueled.

There is a circular self-adhesive sticker in the center of the bottom surface of the fan, which can be uncovered to reveal the internal shaft of the fan. Use a toothpick dipped in a little sewing oil (about the size of a grain of rice) and add it. Attach the sticker again.

In addition, check whether the chassis vibrates, and if the host is not moved slightly, or the handle is pressed against the cover of the case, you can try it out.

The method of hand test inspection is that if the sound of pressing on the hand is low, it is the case vibration, check whether the cover plate screws are aligned, or the quality of the case is too poor. If there are no big changes.

It should be the fan's problem. If you don't have experience in repairing computer hardware, it's better to find a familiar person to help, it's good to focus on the solution, to determine which fan it is, you only need to temporarily unplug the power plug of different fans to quickly judge the beam search.

You can also process it after a while, and it won't damage the device, so don't worry. It's just loud and a little annoying. My computer has been in this state for 2 months and I am too lazy to touch it.

The noise of the computer here generally refers to the unpleasant or decibel noise coming out of the main chassis when the computer is turned on and running, which is usually called excessive computer noise.

This is because there is a problem with one of the major components in the main chassis.

Cooling fan. This is most noticeable with CPU fans.

In addition to this, there are power fans.

Northbridge fan. Graphics card fans and more.

Case. We've got you covered.

Replacing the fan is the quickest route to repair.

However, dripping lubricating oil into the fan motor is also a good maintenance method, which is economical and effective, but it should not be used more.

Because electronics have a lifespan of their own.

This way is like drinking doves to quench your thirst, only for a while.

After a long time, it will also be rice and other hardware.

1.The fan is too loud.

It doesn't matter, just put some lubricating oil into the shaft (lubricating oil for cars) 2The hard drive is too loud.

It's okay, use a screwdriver to fix the hard disk tighter (after a long time, caused by loosening) 3Also ringing.

Check the inside and outside of the chassis with a screwdriver, and tighten it where it is loose! Hehe.

The sound comes from the moving parts and is arranged as follows according to the likelihood of its appearance:

1.Power supply fan. Generally, the bearing is crooked, probably due to quality problems or wear, the simple treatment is to add oil to the bearing, preferably viscous oil, to fill the gap caused by the deformation of the shaft or bearing, and to strengthen the lubrication to reduce further wear; Poor heat dissipation, leading width and concealment cause the fan to run at high speed; Excessive dust accumulation on the heat sink and fan causes poor heat dissipation; The placement is not smooth, and resonance is generated.

2.Drive. Many optical drives will have a sound when placed vertically (it will sound when turned on), so it is recommended not to place them vertically. Some low-quality optical discs can also cause the speed of the optical drive motor to change and make noise.

or graphics card, etc., the same as 1, because the work is important, it is recommended to replace.

4.Floppy drive. Now I use less, and it is easy to have problems when reading inferior disks, or the magnetic head is crooked, so that I repeatedly look for the magnetic track, which can be repaired, but it is not worth it, and I recommend giving up or replacing it.

5.Hard disk. It does not make a loud sound, but the abnormal sound is often a precursor to damage, and it is basically impossible to repair, so it is recommended to back up important files immediately and then replace the hard disk.

Friend, the problem of computer sound is too vague. There are many kinds of sounds. Let's first analyze from 2 perspectives, if the computer can't enter the system and make sound, it is generally a problem with memory and external settings.

Secondly, it can enter the system and make a sound, which is generally a problem of power supply, and the power supply will be lost, and the power can not be reached if there is little, so there will be noise or calling, and the general low voltage will also make a noise. There is also the hard disk, the number of revolutions is very fast when the hard disk is running, if the quality of the hard disk is poor, then there will be noise.

The sound you said is the sound of the front relatives such as the sound in the case, this is generally the sound of the fan, dust removal in the case, depending on the situation is also improved, if it is still very loud to replace the Huiqi Fengzi hand fan! There is also a fan of the case power supply, if there is too much dust, the sound is also very loud, and the dust must be removed.
