The noise of my computer in my home is always louder than that of the unit, and I have asked the mer

In fact, the computer fan is divided into CPU fan and power supply fan, because the fan is used for cooling, the air flow is very large, so it virtually plays a role similar to a filter, long-term role of the computer, the dust in the air will slowly be deposited in all parts of the fan, resulting in poor operation of the fan, especially the rotating connection part of the fan deposits too much dust, and the fan lacks lubrication, it will produce greater noise.

Solution: Remove the CPU fan, use a small brush to clean the dust of each part of the fan, and then use a needle oiler to inject lubricating oil into the connecting shaft.

The power supply fan, the operation method is the same as above, but I don't know if the fan of the power supply can be removed, but it does not affect the cleaning.

If it is really the cause of the fan, I believe that after the above processing methods, the performance will definitely be greatly improved.

It should be a problem with the CPU fan, and the noise can be reduced by adjusting the screws that hold the fan in place.

Nothing wrong if it's not particularly big. Because the home is quieter than the unit, so it feels loud, if you are idle, you can change to a mute, but as long as the fan turns there is sound, and now there are all heat sinks, the kind without fan blades. 200-1000 are available, but depending on your configuration, the following can be up, and the higher ones are not very good.

First, first of all, you must copy and confirm that the hardware is okay. If the speaker is fine, the sound card is fine, and if you've tested it on other machines and it's really good, then you can read on.

2. Make sure all the cables are exactly right. Then power on the speaker and turn on the volume switch.

3. Install the driver of the sound card correctly, if it is an onboard sound card, it is best to install the driver provided on the driver disk of the motherboard.

In fact, the computer does not make a sound, and many times it is because the sound card is not driven correctly. In general, after the sound card driver is installed, there will be a small speaker icon in the taskbar in the lower right corner. ）

Fourth, if you are sure that the driver is installed correctly, then take a look at the volume settings in the computer.

The specific method is to double-click the speaker icon in the taskbar, and check whether the volume is turned off to the minimum in the "Volume Control" and "Waveform" dialog box in the pop-up "Volume Control" and "Waveform".

If these two options are not available in the dialog box, click on the "Options" menu - select "Properties" - select "Volume Control" and "Waveform" in the "Show Volume Controls" and then set them correctly.

Note: Step 4 can only be set up after the driver for the sound card has been installed correctly.

Detailed steps to resolve the computer with noise, cracking, or no sound.

Use Rising Security Assistant to clean up the optimization and system repair, and turn on the volume control of the small speaker to see if it is set correctly.

In fact, the problem is very simple, go to the speaker properties and turn the volume of the microphone to 0 and there will be no noise.

If the plug or audio output end is loose, just find an electric soldering iron and solder it tightly.

The solution to the noise in the computer headset:

When the headset is in use, there is a lot of noise, generally caused by the static electricity of the computer, you can find a thin small copper wire, let this small copper wire as a conductor, and then connect it to the screw of the chassis, and then put the other side of the small copper wire on the ground, so that the problem can be solved;

The frequency of the headphone noise is very high, and the sound is low, generally the microphone is in a high-pitched state, as long as this state is canceled, because the sound card generally does not support such a state at the same time, just set it;

The noise of the headset is very short, and there will be no for a while, this situation is generally due to too much system garbage, and you can also clean up the computer disk and memory, so that the noise will disappear under normal circumstances. Disk defragmentation can also be used;

The noise of the headphones has been continuous, and the above methods have not been solved, which is generally the fault of the headset itself. It is recommended to try to change a headset, if this is still the case, you can use the driver wizard to reinstall the driver and system to try, if there is no noise after changing the headset, the headset is broken;

Sometimes the plug of the headset itself is loose, so we can tighten it with our hands, which will also have a good effect.

Solution: Microphone, mix volume to 80 to 90 percent.

Second, whether the microphone is in a strengthened state.

Solution: Remove the microphone reinforcement. Because some sound cards don't support it.

3. Whether there is a problem with the connection between the microphone and the computer host.

Solution: Disconnect the microphone from the computer, reconnect it correctly, and check if there is any bad contact.

Fourth, whether to use speakers.

Workaround: Use a headset. You must use the speaker, pay attention to the speaker speaker not facing the microphone, (the condition of your own computer room needs to be spacious and good).

5. Is there anything with magnetic fields and sound waves around?

Solution: Take away electrical appliances with magnetic fields (such as mobile phones, fans).

Hello questioner,I'm like this, I reinstalled the system yesterday.,Before the reinstallation, there was no problem with the voice of friends.,After the reinstallation, there was a current tone.,It's they who listen to the current sound on my side.,And then they will hear their own echo when they speak.。

Is there any update driver after reinstalling the system?

Question: My computer was set up by myself two years ago.,And then I didn't update the driver after reinstalling the system and tried it after the update.,The effect is the same.。

Build your own computer? Is the sound card also self-assembled?

The sound card should come with the motherboard.

It's not expensive, and it's a good idea to turn off automatic updates.

Updating the system doesn't necessarily make your computer better, but it will be full of bugs.

It's possible that you've reinstalled a version with a lot of bugs.

It is recommended that you reinstall the system not to pursue the latest version, but to try to choose a stable version [smile] [smile].

Don't blindly pursue the latest version when reinstalling your system, try to choose a stable version [smile] [smile].

Question Okay, thanks! [Eat whales].

The microphone is not turned off, just mute the microphone directly in the main menu of the volume.

The noise basically comes from the fan.

The noise of the fan, the first is the tremor caused by the unsmooth installation.

The second is the resonance generated by high-speed rotation and the chassis, and the third is the howling caused by the design of the heat sink or dirt, similar to whistling, the higher the speed, the greater the tremor, a good fan can automatically adjust the speed, generally a fan with a 4-pin interface, so it may be very loud when it is turned on, and it will be stable slowly.

In addition, the fan installation is not stable, but in the process of trembling, it may move slightly to a relatively stable position, and the noise will also be reduced, or if you gently move the case, the noise will be reduced.

The noise should be a short while, right?,When you turn on, the major hardware of the host is just powered on.,It will slowly stop after entering the desktop.。

This is because the fan in the computer uses oil-sealed bearings, which is related to the ambient temperature, and when the weather is cold, the oil in the fan is solidified, so the sound will be loud at first, and it will become smaller after a while. There is also a situation that occurs when the phone is not turned on for a long time.

Sometimes the CPU and graphics card are running at full capacity, and the fan is spinning at high speed, making it louder.

It will appear like this after a long time, and it is better to clean the ash frequently.

If you have a problem with the sound card, add a separate sound card.

The coil of the speaker is probably a little problematic, or the line is interfering.

Do not plug the mobile phone data cable into the computer to charge.

Is it the machine or the speaker, if it is the audio to change it, if it is the case, open the case to see if the fan and some equipment are not fixed.

Check the program installed on the machine.

According to the situation of my computer, I personally think it should be cleaned up, my dust is a lot, there is a problem with heat dissipation, and it is recommended to clean it regularly.

The fan doesn't work, or the dust is too big, if you can solve this noise with software alone, then the hardware market will not be so prosperous.

I guess it's a fan problem. If you want to be more hands-on, take the power fan apart and get some lubricating oil.

See if it's a fan problem, is the environment clean.

What makes it too loud? If you want to use the fan, take it out and clean it.

Loud? Most likely, it's a fan.

If it's a hard disk, then the problem can be big or small, if it's just a fan (the fan in the case is generally the CPU, graphics card, power supply, some are also on the side of the case), see how it sounds.

If it is a stable noise, then most of it is the fan into the dust, just disassemble the case to blow the dust, and if possible, you can also put some sewing oil on the fan motor. Never put anything like peanut oil

If it's an intermittent irregular sound, then it may be that the fan screws are loose, or the fan blades are rubbing which wire or something, take it apart and take a look.
