hardware and its function

POWER SUPPLY



Form a voltage box listirik that attaches to the back of each computer and have the CPU power cable to be connected to a hardware component that is in the CPU. Power supply also supplies electrical energy to one or more energy burden.

function

- Changing the AC voltage into DC

- DC supply voltage to a component that requires the current and voltage on the motherboard.

- Controlling the electrical current / voltage to stay awake.

troubleshooting

Notification of problems that occur frequently regarded as a problem caused by a hardware component in the form of memory, VGA card, or motherboard without expecting an error occurs on the powersupply that we use. Here are examples of problems that occur:
+ Computer restarts itself when the system is working.
+ The computer turns off after a while operated.
+ Intermittent parity check or other memory-type errors.
Harddrive and fan + sec. does not rotate synchronously.
+ Electrical shock is felt in the casing or connector
+ Power-on or system startup failure or lockups
Sometimes the boot itself + sec. spontaneous lockups during normal operation.
+ The system is fully dead.





MOTHERBOARD


Shaped board (board) that has several major electronic individual slots that can be paired to another board, ranging from the processor, memory, sound card, display adapter, and so forth. Between the slots on the mother board, there is a special slot for the installation of the processor, called the socket and slot 1. Socket motherboards have some kind of different, according to the development of the processor.

function
- The place to put or attach various components such as processors, memory, sound card, vga card, etc..

- Media data transfer from the working components inside the computer.

- Set the power at each of the components on the motherboard

troubleshooting

Often there is a problem caused by motherboard hardware components installed on motheboard or damage to the chipset used on the motherboard or I / O other.

+ The computer can not burn or often referred to as "motherboard + blank" when the ON button has been pressed on the casing without any sound. Typically, this occurs because of:
-Power supply is faulty or the motherboard power supply cable is placed in inaccurate or loose
-BIOS is damaged
- Errors due to overclock the CPU clock on the computer
- The processor is mounted is damaged, or a socket that is used not in accordance with the motherboard.




PROSSECOR (CPU)
Is a component of the IC chip or a rectangular shape of the brain and the computer controlling the process performance, with the help of other components. Unit of the processor speed is the MHz (Mega Hertz) or GHz (1000 Mega Hertz). The larger the value, the faster the process of execution on the computer

function


- Place all of the instruction set computer program.
- Managing the performance of all activities on the computer.

troubleshooting

Problems on the processor typically causes the display to blank screen with no sound whatsoever. This happens because:

1. Processor die or damaged
2. Burn from the processor temperature is too hot for doing Overlock or because the processor fan is not working

1. Main memory
The processor can only store data and instructions in a register that is small so that it can not store all the information needed for all the programs. To overcome this processor should be equipped with larger storage capacity, the main memory. Memory size is indicated by a byte unit.

function
1. As a data storage device and the program is temporary, it only works when the computer live.

troubleshooting
1. The computer made ​​a sound "beep" a long time without displaying the image on the screen when the computer starts up

2. Installation of two pieces of RAM that do not fit often cause problems on computers, among others:
The computer would often hang and blue screen appears when we work in an application program or are playing games

-Computers are also often do not live or booting bias when lit

1. If installed with a capacity of RAM is not enough, the computer will be slower performance in the reading of the data or run the application program.

2. Damage to the ROM memory type will result in blank computer or can not live at all

HARDDISK

Is the component that contains a rectangular platter or dish that is similar to phonograph records, head, electronics board, motor, and other components, which are coated or wrapped by a strong casing.

function

1. One of the computer booting tool.

2. Storage media operation system (OS) used on the computer

3. All of the data storage medium in a large capacity on a computer

Trobleshooting

Many computer problems due to damage to the hard drive so the computer can not be used. Here are some of the problems caused by damage to the disk, namely:

1. The computer can not boot or startup

2. Computer hangs or restarts itself

3. Difficulty in reading and open data

1. Video adapter or GPU

Is a computer hardware component that connects the graphics processing equipment with a monitor output equipment. On the old computer, the graphics processing performed by the main processor. However, as the development of computer technology today, has been designed

Video adapter with hardware components has its own processor, called GPU (graphics processor unit) or the internal memory sehiingga chipset and load the main processor performance becomes more reduced.

function

1. Port connecting the data processing equipment with a display output device / monitor

2. Maximize the function of the screen so it can display graphics in resolution and color quality is best.

3. Can accelerate the performance of all software operation system (Windows)

And 2D and 3D software applications

1. Support the use of computers for games that are now widely based on 3D games software

2. Display the best image quality for movie playback types of CD and DVD

troubleshooting

There are not any images on the screen because the screen is not attached to the connector on the VGA card or plug is not installed properly

Sound Card

Is a computer hardware components which form the chipset on the motherboard or card PCB (printed circuit board) is mounted on a PCI slot on the motherboard, by having four main components to translate analog and digital.

function

1. Process data in the form of audio or sound.

2. A connector audio output to speakers

3. As a liaison to the computer voice input through a microphone.

troubleshooting

Can not make a sound through the speakers or the sound coming out Akif not clear, which is caused by:

1. Sound card drivers not installed

2. Installation of sound card in PCI slot on the motherboard that is not right and fitting embedded in the slot.

3. Installation of the cable jack on the channel out on the sound card in the chassis and speaker

4. There is a broken connecting cable between the sound card in the chassis and speaker

5. Sound card is damaged or defective active speaker

Heatsink Fan (HSF) or Cooling Device

Cooling equipment is box-shaped or round, made ​​of aluminum material and on it there is the fan that will spin when the computer is on. Kebbutuhan HSF become a staple in almost any computer because of computer hardware components inside the casing using the HSF respectively, from the processor, VGA card, hard drives dn competing to provide the facility of high quality HSF components in competing in the market.

function

1. Cooling the hardware upon which is placed HSF.

2. Processors will not work if there is no heatsink fan on it.

3. Absorbing the heat generated by the processor at work and is equipped with a cooling fan on it so that the processor temperature remains stable.

4.Guard air circulation inside the casing.

troubleshooting

Hanay usually occurs on the fan is not spinning or dead. This is a fatal problem that makes the hardware does not function normally, especially if it occurs on the fan attached to the processor. Processors will not live and work normally so that the computer turns off completely.

casing

Brain is putting a wrapper or processing hardware components that serve to protect the hardware components from outside interference. In general, often called the CPU casing.

function

1. Putting a hardware component, such as power supply, motherboard, floppy disk, CD-Rom, DVD-Rom.

2. Sistemkarena performance determinants related to the temperature generated by the hardware components.

3. Proponents of computer display. If the casing has an attractive design, one would be more pleased and excited to work with the computer.

Trouble shooting usually occurs on the power supply attached to the rear casing abgian.
