Computer case sounding problems!! Masters, please come in

1. When you open a web page or open my computer, the sound of "Didi" may be the sound of the hard disk, and the general hard disk will emit this sound after several years of use.

2. There are also floppy drives being issued"However, this sound is very loud, sometimes it doesn't happen often, occasionally when it is turned on, or it is continuously moving.

3. When you change the theme, the machine makes a 120 sound, and there is no sound after restarting the machine, and there will be another after a while, which I think is a problem with your computer system files.

My personal recommendation.

I've been using the Dell computer in my office for 3 years, and now it's also a click of the mouse, opening the web page, and opening my computer. will make a "drip" sound).

2. Now the floppy drive is basically gone, enter the BIOS and turn off the floppy drive boot option.

3. Reinstall the system, and the theme sound will be normal.

4. You may add more memory modules, and in some cases, you will not read and write through the hard disk cache!

Is it installed with a floppy drive???

If you install a floppy drive and some U disk viruses, it is easy to run some programs that will naturally make a sound of reading the disk, this virus generally can't kill soft, can only be killed by hand!!

Analyze what kind of situation you are!!

Let's take a look at the installed theme first.,Change it and try it.,I don't rule out what spoof theme (or spoof program.,It's similar to a virus.,Very annoying kind).

Maybe the computer has been used for a long time, and there are more junk files, so it's best to use optimization software to optimize it! If it doesn't work, let the company change the configuration!

You'll want to make sure if you have Windows themes installed, some themes have sounds.

Does the buzzer make a sound? Maybe it's a memory issue.

I didn't know what you said was that there was no sound from the speaker interface on the front of the console, and in this case it could be that the audio cable connecting the motherboard to the case panel was not connected.

If there is no sound in the audio interface at the back, it is not a problem of connection argument, in this case, it is necessary to consider whether it is a problem with the sound card driver, and the serious situation may be that the audio chip of the motherboard may be burned out together because the power supply is burned out!

Therefore, it is recommended that you take the computer to the professional to see the place where it is repaired.

The reason for the noise is due to the lack of oil and aging of the fan.

The host includes power supply fans, CPU fans, and graphics card fans.

The problem of abnormal noise is often emitted by CPU fans and power supply fans, if you don't want to replace the fan, we can solve it by cleaning the fan and adding lubricating oil, and it goes without saying that the dust is cleaned up.

Refueling method: uncover the plastic film at the bottom of the fan (first remove the fan so as not to get everywhere), after disassembling the plastic film, you will see the hinge, dip it in a little lubricating oil (it is best to sew machine oil Engine oil can also be, do not use household oil), be careful to drop on the fan bearing in an appropriate amount, so as not to overflow, after adding a few times to turn the fan to let the oil invade the bearing, and finish the plastic film on the stick.

Just give the fan a little bit of reason, or grease......

The sound emitted inside the main unit is the sound when the fan rotates.

If there is noise, please clean up the dust in these parts of the fan (CPU fan, graphics card fan, northbridge fan, case power supply fan), check whether the fan motor is normal, and replace the fan if not.

We have had this kind of problem in our department, and it usually takes a while for the computer to appear.

It is necessary to properly remove the dust, especially the power supply, and those connecting cables.

Don't touch the fan, don't run to the case wall, pay attention to these problems and you can solve them.

If there is no sound on the computer, you can analyze it by following the steps below:

First, first confirm that the hardware is fine. 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, the task is in the lower right corner.

There will be a small horn icon in the bar. ）

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.

You look at the small speaker at the bottom right of the screen to see if it's muted or if the sound is zero.

If the driver conflicts or the sound card is stiff, you can try a different version of the system!

Check whether the hardware is plugged in again, restore the system disk, and see if it works.

Buy a sound card, and everything is solved.

I've seen this situation that is not easy to solve and just reinstall the system.

When the computer is just turned on, the hardware and software start to work, and the cooling fan is overloaded, of course, it will ring;

After the system is started, the hardware and software are working normally, and it will be fine;

Solution: 1. Software: try to reinstall the system, and then update various drivers;

2. The above can not be solved is a hardware problem, this is a little troublesome, the buzzing sound may be a problem with the speaker, but it may also be a problem with the sound card driver, if the speaker is a problem, you have to change the speaker. Either the inside is dirty, clean up the whole machine.

Your computer should be set to boot from the optical drive first, and it will look for whether there is a boot disc in the optical drive when it starts. Usually, don't leave a disc in the optical drive.

1.Right-click on the computer, properties, hardware, and see if there is a small yellow question mark in the list, if there is, your computer driver is not fully installed.

2.Check to see if your speaker cable is plugged into the corresponding jack.

3.See if your stereo is on and the volume is on.

4.Look at your computer's audio manager, whether you have muted it and turned on the computer.

Hello, friend. You first go to the Device Manager and take a look, if it shows an exclamation point, then you need to reinstall the system. If you've just reinstalled your system, you may need to install a sound driver.

In this case, it should be virus destruction or other factors that cause the sound card driver to be broken, the easiest way is to install the driver elf fire drive life, which will help you find the right sound card driver,**After installing it, you can do it, what should I do if the computer (notebook) has no sound?

Reasons why there is no sound on the computer:

1.The computer speaker cable is not connected, the speaker is not turned on, the volume of the speaker is placed in the minimum position or the speaker is not powered by power, or the state thick interface of the audio output and input behind the sound card is plugged in backwards. This causes no sound on the computer.

2.In the volume control in the lower right corner of the computer screen, set the volume to the minimum or set it to mute.

3.The computer was infected with a virus Trojan horse, and the virus destroyed the files related to the audio processing, and the special book infiltrated the town when the system components related to dsound were destroyed by the virus.

4.The sound card driver is corrupted or the driver is installed incorrectly with the driver of the unsupported device.

The solution to no sound from your computer.

First of all, you should check whether the speaker switch, signal cable, and volume control are normal. Then, check if the settings related to the loud in the control panel are normal. If the driver is faulty, these options are grayed out and left in an unselectable state.

Use Kingsoft Antivirus or Kingsoft Guardian to quickly check whether the computer is damaged by viruses. Generally, we don't need to do a comprehensive scan of the hard disk, we only need to use quick scanning, scan for 3-5 minutes, and follow the prompts to remove the virus.

If none of the above methods work, you should check the control panel, set up the shouting and standby manager, check whether the sound card driver has a yellow question mark, if so, you only need to reinstall the sound card driver again, and restart the computer to fix it. Usually the driver of the sound card and the driver disc of the motherboard are together, insert the disc of the motherboard into the optical drive, select the sound-related program according to the prompts to install, and the step-by-step operation can be completed. Follow my method to solve the problem, and ask me if it doesn't work.

The sound of your device is at its lowest. Turn it up and try it.

This is due to chassis resonance. The vibration of the chassis mainly comes from the mechanical running parts, the chassis fan, the CPU and the graphics card fan, which is the mechanical vibration generated by the computer**.

1. Open the case to listen to the noise**, you can re-disassemble and fix the case fan, CPU and graphics card fan, and move their position slightly sideways to eliminate the conditions caused by resonance.

2. Check whether the fixing screws of the motherboard are missing, and if they are missing, they will be completed. Stable and firm motherboard installation can reduce the probability of mechanical vibration driving to the chassis housing;

3. If the motherboard fixing screws are fully installed, you may need to adjust the installation position of the motherboard screws, move the iron piece of the network cable slightly, or pad a piece of paper with a suitable thickness there (you can fold it several times with tissue paper to ensure that its thickness is just between the motherboard and the chassis shell, and it is compressed), this buffer pad can ensure that the motherboard does not drive in the direction of the chassis due to the vibration generated by the fan.

See if the hardware inside is fixed, disassemble it and listen carefully to the sound of **, and then find a repair to solve it.

In a word: find a solution to assemble a computer!
