Chassis sound issues with Lenovo Jiayue series computers

The computer has a sound, let's first study the parts that may emit sound inside the computer: 1. Fans (there may be 2-4, power supply fans, CPU fans, graphics card fans, and northbridge fans) 2. Optical drives 3. Hard disks.

Exclusion method: Open the side cover of the host (if you can't open it or don't have the courage to open it, you don't have to look down, just call **Contact customer service to repair it, here is a hint, there are individual garbage brands of computers are not allowed to open the test cover, and people don't care about repairing it after opening it privately.) Most well-known brands are OK, judging from the name you provide, it should be Lenovo, then you can open it, it doesn't matter if you can't call customer service again), see if the fan is rubbing against what line, if it is not turned on (don't be afraid, be careful, it's okay), press and hold a rotating fan with your hand to listen to whether the sound has decreased, there is a problem with the fan, replace.

If you can't reach for the fan of the power supply, you can use a small wooden stick to get stuck, the graphics card fan is on the downward side, look carefully, the integrated graphics card does not have a fan, and most brands of North Bridge fans do not have it. There is no look at the optical drive; Is there an untaken disc in the optical drive?,If there is no optical disc optical drive is no sound under normal circumstances,There may also be sound when the hard disk reads and writes,There is no way,As long as the work is normal, the manufacturer will not change it.,Bear with it.。 If it's all right, see if you're too sensitive.

Why don't you find a feng shui gentleman and see if it's haunted)

Addendum: The noise of each computer is not the same, which is caused by individual differences in parts, even if two computers of the same model are bought on the same day. In addition, because the family environment is generally quieter, it seems that the computer at home is more noisy than the computer in the unit, and you basically can't hear the noise of the computer in the shopping mall, the environment is different!!

Maybe you have a problem with your fan, and the case of the Lenovo series is almost silent.

My computers are silent.

It may be that there is a problem with the engine of the computer fan, if it doesn't work, take it to the computer company to change, and the audio may be that the interface is not plugged in well, or the interface is plugged in wrongly, otherwise there is a problem with the audio or the interface or the connecting cable.

It is estimated that your fan may have a little problem, if the sound is too loud, hurry up and find after-sales service.

1. Check whether the sound card, cable, speaker and other devices are connected normally. This problem is usually the most common problem.

2. Open the control panel--- Add new hardware--- Next, after the search is completed, click "No, I haven't added this hardware", click Next. In the dialog box that appears, check "Click Done, shut down the none, restart to add new hardware". Note that this refers to shutting down and then starting, not restarting.

In general, the problem can be resolved after rebooting.

3. Right-click "My Computer" --Properties--Hardware"--Device Manager", and open "Sound, ** and Game Controller" for any problems, that is, see if there is a yellow one in front? If so, uninstall it, then put it into the CD drive and reinstall the drivers for this device.

4. If the "Device Manager" - Sound, ** and Game Huyan Controller" is no sound card hardware, then you have to find your sound card, including the integrated sound card, the model must be accurate, after confirming that the sound card is found, then put it into the system drive disk, install the sound card driver.

5. When there is sound but no small speaker, open the control panel --- the sound and --- volume of the device, and put the check mark before "put the volume icon into the taskbar", and there will be a small speaker in the taskbar after restarting.

6. When there is no sound and no speaker, open the control panel--- add and remove programs--- add and delete windows components, and put in.

I found the problem, it was the heat sink of the CPU that was too dirty, and it was solved after cleaning it.

There are actually many reasons why the computer does not sound:

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 audio output and input interfaces behind the sound card are 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.A virus Trojan has been infected in a computer, and the virus has damaged the files related to audio processing, especially the system components related to dsound.

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

What to do if there is no sound on the 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, device manager, check whether the sound card driver has a yellow question mark, if so, you only need to reinstall the sound card driver again, 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.

This situation is mostly a matter of sound card or multi** interface It may be caused by a short circuit in the power to 800 hits** If it doesn't work, it will be repaired Good luck.

Hello, you can open the case, listen carefully, check them one by one.

1. Open the case, find out which fan (power supply, CPU, graphics card) is the problem, turn off the power supply, remove the fan (be careful not to remove the heat sink, if you remove it, apply silicone grease glue when you put it on again), remove dust, uncover the plastic oil seal, on the roller, put a little antifreeze lubricating oil or sewing machine oil, seal it, and then put it on as it is; If the fan is badly worn or broken, replace it with a new one.

Second, the CPU heatsink design problem, the fan airflow produces noise, replace the heatsink.

3. Listen to whether the sound of the hard disk is abnormal, if there is, repair the hard disk.

Fourth, whether the chassis and motherboard are loose, tighten the screws.

5. Sort out all the cables in the chassis and plug them in tightly.

Sixth, listen again, what else is loud, and rule out the symptoms.

The tables in the town are trembling, this is a bit exaggerated, the CPU fan is not installed? Or there is a problem with the CPU fan, brand machine, it is recommended that you ask after sale.

The chassis is noisy, it depends on the specific situation! What is your computer configuration? Is it a discrete graphics card?

If you have a discrete graphics card, do you have a fan, and if your motherboard South Bridge has a fan! In this case, you can open the case, see how many fans there are in your computer, first turn on the CPU fan, and then unplug the power cable! If the sound goes away, it means that your CPU fan is faulty, and you can replace it!

In the same way, test the South Bridge fan at once, and the graphics card fan, of course, this refers to your motherboard or graphics card if you have a fan! If you have tried all of these in turn and still can't solve your problem, then you can definitely tell you that there is a problem with your power supply fan! You can simply change the power supply, clean the dust from the power supply, and replace the fan!

Note: The time must be short when testing the abnormal sound of the fan, if the test is long, it may cause hardware damage!! There is also high voltage in the power supply, remember not to disassemble it yourself!

Replace inferior hardware, eliminate sources of noise, and if needed, **.
