Computer recently inexplicably noise, are buzzing hum, very large, do not know where is issued, generally as long as the indoor air-conditioning will be open noise. Have not before, now have, sometimes boot to select the operating system and then cut off the power cord, and then plug in the power cord can be resolved. Sometimes plug the power cord can also be res
from the characteristics of an existing sequence. It can only be determined based on the sequence generation method. The pseudo-random series has good randomness and correlation functions close to white noise (Delta functions), and has pre-certainty and repeatability. These features make the pseudo-random sequence widely used, especially in CDMA systems, as a Spread Spectrum Code has become a key issue in CDMA technology.

How to solve the computer noise?
The noise of the computer comes from these aspects: the power supply fan, the CPU fan, the chassis fan, the video card, the noise of the power supply fan, the noise of the hard disk and the opti
Many friends have encountered computer noise problem, let's talk about the computer noise is the reason. Generally speaking, the computer produces the noise mainly has the following several possibilities.
How to solve the
, carefully inserted large fan, the central fan with a trademark circular adhesive carefully opened, you can see the center of the central Axis exposed, with Vaseline (very cheap, pharmacies have to sell) carefully coated, carefully sealed with a trademark of the round stickers can be. -Principle: Vaseline mostly used to smear hands, to prevent dry skin in winter, chapped, it has a feature: when the fan will produce heat when working, Vaseline will gradually melt into the fan bearing lubrication
One, the computer noise is big how to do fan reason
In many people's view, heat dissipation and noise is a pair of irreconcilable contradictions, because want to heat good, the fan will be big, but also increase the noise. This is a fallacy, in fact, a well-designed notebook, not only to have a good cooling, but also
If a computer is used for a long time, there will be such a problem, computer noise is also one of the frequently encountered problems. Computer after a long period of operation and work, you will hear "Cha Cha, ho ho" voice, it is annoying, I want to hit it. Where these noises come from, how to avoid this problem or h
To build their own mute computer, it is not a very difficult thing, just a few key accessories on a little choice, you can easily achieve.The noise of the computer comes from these aspects: the power supply fan, the CPU fan, the chassis fan, the noise of the video card fan, the noi
First, let's start by saying where the noise from a mainframe computer comes from. We know that the main components of computer host include: Processor, memory, video card (set video card ignored), motherboard, hard disk, power and other computer hardware, easy to generate noise
computer hard drive to make noise solution:
Eliminate Power fan noise
The power supply fan noise is usually divided into rotating noise and vibration noise. The rotational noise is ge
deformation, touch the inner wall, emitting noise. The solution is to take a blade in the scratch place gently scraping a few, increase the distance between the fan and the wall, to avoid both friction.
Third, eliminates the hard disk noise
The noise from the hard drive may come from its own vibrations, and this is not just about making annoying noises, but
Sources of computer noise:
Main parts of computer host include: Processor, memory, graphics card (set video card ignore), motherboard, hard disk, power and other computer hardware, easy to produce noise accessories mainly include: Processor (mainly cooling fan), video card
What about the loud computer noise?
In fact, most of the computer noise due to the computer's internal cooling fan dust caused by too much, so the solution is generally mainly clean. To solve the problem of computer noise should
Sometimes when you use a computer, you may hear a buzzing sound from your computer, I believe many friends have encountered, especially those who are older or long time did not clean the computer, the noise is particularly large, sometimes this noise has seriously affected o
, emitting noise. The solution is to take a blade in the scratch place gently scraping a few, increase the distance between the fan and the wall, to avoid both friction.
Eliminates Hard drive noise
The noise from the hard drive may come from its own vibrations, and this is not just about making annoying noises, but about the security of the hard drive. Becaus
Recently there is a Win7 system in the use of computer listening to music, found that the computer has a murmur, singing out of the song are completely different, users do not know what is the problem, so very distressed, then Win7 computer has a noise how to solve it? Today good system reload assistant for everyone to
one, notebook hard drive noise
1-1, notes the hard drive operation Sound
When the hard disk reads the data or writes the data to the hard disk, it produces the sound of the disk working, which is the normal sound
1-2, the notebook hard drive abnormal sound
If the notebook hard drive is too noisy, or repeat the "click" Sound, check the disk status using the Check Disk feature (turn on the computer icon,
not reach the requirements, the noise will become more and more serious. So this item should be based on the sound of the situation to the specific choice.
Select one, it does not completely eliminate the noise, but also to other operations. Go to Registry Editor, expand the "Hkey-local-machine/system/currentcontrolset/services/audiosrv" item in turn, locate the "DependOnService" item on the right and dou
1, CPU fan
If you hear a buzzing sound, it is estimated that the power of the CPU fan sound, because the fan used too long, the internal accumulation point of dust will appear some small hum. Generally open the cover to clean the fan can be resolved. can also add some lubricating oil, but not familiar with the computer can not be free to refuel oh.
2, the line was collided
If you hear a sound that has a squeaky squeak, it may be that many times the
When the computer used for a period of time, the process of running more and more slowly, sometimes there are blue screen, crash and other phenomena, the computer running noise is also more and more big ... My beloved computer is no longer the color of the original, what is going on in the end? This is mainly because y
