The Sound problem in Computer

The computer is indeed a need for a fairly complete. The facilities can be found on a computer other than as a means to assist the work, communication, entertainment and even a very incomplete.

From the computer we can play both games online games and offline games, but it also we can watch movies or just listening to music while doing a job.

But what happens when our favorite movies, your favorite music and your favorite games are played on a computer can not make a sound, aka dumb, certainly very annoying as watching a movie without sound is impossible, play music without sound too impossible although the game could be played without sound but it would be much better if the games are played can make a sound so games played by the player feels real game.

Then the next how to resolve the issue so that those games, music and films of our choice can be played on a computer or laptop then you should consider the following steps to find out his mistake.

The first thing to check is to plug in audio cables installed between the speaker and the Central Processing Unit (CPU) installed on the sound card (audio card).
In the audio standard card there are three hole connector as the Blue and Green Line In as Speaker Out and Purple or Red as Microfon.
Pair of speaker cable in accordance with the existing color on the audio card.

The next step is to make sure that the speakers are active you are in the ON state, and could it not also solve your problem then the next step into the device manager, by right click on my computer and select properties then click on hardware-device manager or it could be a how to click Start-Control Panel, System, Hardware and then select Device Manager.

Note on the Sound, Video and Game Controllers, whether you are an exclamation point (!) Or question mark (?) If there is one sign that it has been ascertained that the sound card does not conform with the drivers installed on your operating system, perform the driver installation re- accordance with your sound card.

Keep in mind that if the sound card in your computer's sound card is on board then the driver used is the mainboard while the sound card drivers installed on your computer is a stand-alone sound card at time of purchase will usually sound cards gained a disc compact disc ( CD) in which stored the sound card drivers, use the original driver cd for installation of the driver until an exclamation mark or question mark does not appear again in device manager.

Motherboard maintenance tips

he computer today is no longer a need for people dispossessed but rather the basic needs that must exist in particular for all types of business. Sure there are many also who have not used the computer alias computer manuals (engine type) as a tool for typing.

Imagine in the past that have not been so familiar computer, in case of power failure, then the office staff could still work using the makeshift lighting candles because at that time kompunter still rare, compared to today, when the power goes out then all the employees that complete rest because the average in every field of endeavor has been to use computer facilities as a basic working tool, while the computer power required to form an electric current flow in case of power failure so we certainly can not do anything but waited until the electrical re-energized.

This electrical problem could affect the safety of our computer machine tools one of which is the motherboard or mainboard.

The motherboard or mainboard is very important for the smooth process of the data for all components ranging from the processor, memory, data storage media (storage), a component of Input-Output (I / O) cards (cards) stuck on this mainboard.

In order for this mainboard can be longer or durable in usage it is necessary to consider the following quick tips:

1.     Use the Uninterruptible Power Supply (UPS) and power supply voltage stavolt as a safety so that no influence on the performance of the mainboard when the voltage changes abruptly. 
2.     Note the cleanliness of the inside of the particular CPU mainboard, mainboard do the cleaning when soiled using an air compressor or can be by using brush approximately 3 months or as needed. 
3.     Existing air vents in the casing should not be closed so as to accelerate the exchange of free air into the room Central Processing Unit (CPU) in order to maintain the temperature in the CPU space. 
4.     Clean slots or konetor that connects the mainboard with the other components of the dust once a month. 
5.     When cleaning in order to always pay attention to whether or not the bolts that remains in the mainboard, if there is immediate lift from place to avoid a short circuit (shorting). 
6.     Do not let the computer is not used / not turned on for a long period of time. Try at least 3 times used / turned in a week. 

So little tips on caring for the mainboard as well as answers to the questions asked a visitor of this blog to learn computer science.

Various methods to improve the performance of the disk

There are various methods used to improve the performance and capability of the disk. The methods are usually used to improve performance, it will involved many disks as one storage unit. Each block of data is separate into some sub block, and is divided into disks (striping). When there are data transfers, the disks will work in parallel, and increase the transfer speed in reading or writing data. Combined with the rotation synchronization on each disc, then the performance of the disk can be increased. This method is known as RAID - Redundant Array of Independent Disks. Beside that RAID performance problems may also increase the reliability of the disk by using additional disks to store the parity block or as a mirror of the data on the disk.

Usually some computer motherboards already support with raid10. Raid10 using a set of disks with striping at the block level without redundancy. So just do the striping blocks of data into multiple disks. Excess of this level  has already include access to several blocks and can be done in parallel so it can be faster while sending data. However lack of access per block, just like there is no improvement, less reliability in the absence of data backups with redundancy.

The test result of entrylevel AMD graphics card

Competition class graphics card for making us a little bit oblivious to the graphics card entry-level class. In addition to the modest performance, the actual entry-level graphics card still has its own charm, like the three graphics cards from AMD this entrylevel.

If we look, the graphics card competition which currently tend to occur only in mainstream classes lively and high-end only. We are always treated to the facts of how AMD and Nvidia each attacking one another with mainstream graphics card product products and their high-end.
Call it a competition between the Radeon HD 6950 and GeForce GTX 590. Or, the war in mainstream classes between the Radeon HD 6850 and GeForce GTX 560 Ti. Similarly, the manufacturer. Vendors such as Asus, MSI, HIS, Sapphire, WinFast, and the others, launch competing products based on the graphics chip in different variants.
But, there is still one more segment which we feel somewhat "quiet" and "less attention". Yes, the graphics card is an entry-level class. The number of graphics card products in this class tend to be quite a bit with his new-variant minim.Varian innovations were rather rare. Look at Nvidia. For the GeForce 5 series, as of this writing, Nvidia has only one variant in the entry-level class, the GeForce GT 520. In addition to the GeForce GT 520, Nvidia just rely on a variant of the previous series such as the GeForce GT 430.
Actually, the lack of variants in the entrylevel class is understandable. The enthusiast-user who likes to play the latest games would require a graphics card capable of processing the game well. While the graphics card is an entry-level classes generally have limited ability for these affairs. Yet behind keterbatasnya of the performance in the game, the graphics card entry-level class has several advantages own. Prices are affordable clearly the main points. In addition, the graphics card in this class can also be relied upon for multimedia purposes like watching high-definition video. Entrylevel graphics card power consumption is very economical.
If we had a new call entry-level graphics card from Nvidia, AMD also has an entry-level graphics card in the Radeon HD 6000 series. Unmitigated, AMD seems more serious this time to fill this market by launching several series at once. Well, the discussion this time we tried to test the performance of several entrylevel graphics cards from AMD. Our test includes performance for the multimedia business, gaming, as well as compare it with the graphics card in it.
