What should I do if there is noise on the hard disk and the hard disk of the computer is making nois

First, first confirm that the hardware is fine. 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.

When you ** some files or run some programs, the hard disk will make noise, when your programs stop running, the noise of the hard disk will stop, this is a very normal phenomenon, it doesn't matter, my computer is the same, by it is to open the anti-virus software and** movie, the noise is even worse.

<>Eliminate power supply fan noise

Power supply fan noise is generally divided into rotational noise and vibration noise. Rotational noise is generally caused by a lack of lubrication in the fan bearings. The solution is to apply a few drops of sewing oil to the fan bearing.

Vibration noise is generally caused by unbalanced fan blades, loose blades on the shaft, and excessive bearing clearance. If it is the accumulation of dirt on individual leaves, it can be removed in time; If the fan blades are missing, asymmetrical, or the bearing clearance is too large, it is best to replace the power supply fan with a new one.

Eliminate CPU fan noise

The bearings and fan blades of the CPU fan are the most likely places to cause noise, and after long-term use, the bearing of the fan may be too much friction due to lack of oil, resulting in large noise, so you can add some sewing oil to the fan shaft. The specific operation is to carefully uncover the label on the fan shaft, add oil and then cover it. If the quality of the fan blades is not very good, after a period of rotation, the fan blades may be deformed due to heating, touch the inner wall, and make noise.

The solution is to take the blade and gently scrape the scratch a few times to increase the distance between the fan blade and the inner wall to avoid friction between the two.

Cancel hard drive noise

The noise of the hard disk may come from its own vibration, and at this time, it is not just as simple as making annoying noise, but also involves the safety of the hard disk. Because the vibration caused by improper installation may damage the hard drive, the drive installed horizontally must be parallel to the chassis, and the vertically mounted hard disk must be perpendicular to the bottom surface of the chassis and not skewed. The most important thing is that the hard drive must be in a stable state (it is recommended to use more than three screws to fix the hard drive), but at the same time, it is important to make sure that the set screws of the hard drive are not too long or too tight to prevent damage to the circuit board and platter.

Eliminate chassis vibration noise

In order to eliminate the vibration noise of the case, we can pay attention to the hardness of the case and the connection between the case and the cabinet when purchasing a computer. Chassis with materials that are too thin and use too "economically" are not strong. Gently squeeze or twist the box by hand to check whether its hardness is acceptable.

A case with a screw-on lid and body is more stable, while a screw-free case is prone to vibration, so it's best to consider it when buying. In addition, some appropriate shock absorption measures can be taken during installation and use, such as attaching a 3 4 mm thick plastic foam strip to the parts of the box lid that are in direct contact with the box body, and then tightening the box cover.
