Win7 sound card noise problem. How to fix win7 sound stuck

It looks like your computer speaker is broken.

Win7 sound freeze solution:

3 In the new dialog box that pops up, switch to the "Enhancements" tab and enable "Disable all enhancements" that is not enabled by default (that is, check "Disable all enhancements").

If you can be sure that your computer is not under-specified, update your sound card driver.

My sound card also had noise after the upgrade, and after a day it will be fine.

Computer noise: power supply fan noise, CPU fan noise, optical drive noise, hard disk noise and chassis noise.

1. Power supply fan noise: Power supply fan noise is divided into rotation noise and vibration noise. Rotational noise is generally caused by the lack of lubrication of the fan bearing, which can be applied to the fan bearing with a few drops of light lubricating oil (e.g. sewing machine oil).

Vibration noise is generally caused by unbalanced fan blades, loose blades on the shaft, and excessive bearing and clearance. If it is a dirt accumulation of individual leaves, it is enough to remove the dirt; 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.

2. CPU fan noise: CPU fans and fan blades are easy to cause noise, and the bearings of the fan may make a lot of noise due to too much friction due to lack of oil after long-term use. You can tear off the label on the fan hinge, add some oil and then cover.

It is not advisable to replace engine oil with vegetable oil here, because over time, vegetable oil will become viscous and affect the heat dissipation of the fan.

3. Optical drive noise: As the name suggests, optical drive noise is the noise generated by optical drive. You can use virtual optical drive software to make some commonly used optical discs into images and store them on the hard disk.

You can also use the optical drive deceleration software to slow down the optical drive, the current high-speed optical drive is completely for the market competition to speed up the crazy speed, you can use nero drivespeed to slow down.

4. Hard disk noise: Hard disk noise comes from the vibration of the hard disk. Horizontally mounted drives should be parallel to the chassis, while vertically mounted drives should be perpendicular to the underside of the chassis and should never be skewed. The most important thing is that the hard drive must be tightened and not overtightened.

5. Chassis noise: If the chassis makes noise, a styrofoam strip should be pasted in the appropriate place, and then the chassis cover should be tightly covered.

Since it is a brand computer, if it has not reached the warranty period, you can't open the case.

It should be a matter of gray and sunny. There is a baffle at the back to suck it off with a smaller vacuum cleaner head.

The solution to the noise and current sound of the microphone: First, the main problem is the problem of non-interference sampling ability, which is reflected in the microphone is the collection, and the sound card is the selection.

Second, the power supply problem, may be the current sound caused by the power supply; 3. The quality of the earbuds themselves; Fourth, the sound card problem, the explosion or noise of the integrated and low-end sound card is inevitable; 5. Software setting problems; 6. Network issues; The details are as follows:

1。Your microphone, whether the mix is pulled to the maximum.

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

2。Whether your microphone is stepping up.

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

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

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

4。Whether or not you use speakers.

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

5。Look around you to see if there is anything around you that has a magnetic field, a sound wave.

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

6。Is there a problem with your sound card or microphone.

Solution: Give the recording tone in the state of playing.

7。There is no power leakage from your computer's motherboard.

You should ask this question directly to computer companies and computer software companies. Look at what their current technology can make to computers without electrical sounds and noises? If there is no sound! There is only one always possible! The computer is not turned on! There is no sound to be delivered!
