how to assemble computer

Stages - Stage Assembling Computers:
1. Make sure all equipment and materials that will be assembled was prepared.
2. Furthermore, before starting to assemble, we will do the checking on the mainboard. How: Install
Processor in socket on the mainboard processor (note the sign), connect the
Mainboard with Power Supplay, pairs of speakers as well. Then try on. When the
outgoing speaker beep sound repetitive, it means the mainboard is still healthy.
3. Then we will match the aperture / mainboard with the bolts in place of the existing bolts
on cashing. Note the hole anywhere that we can use later to membaut mainboard on
Cashing. After that install the mainboard and make sure all bolts are tightened.
4. Further pairs of RAM (also attach VGA card for VGA mainboard that is not ON Board),
then connect with the monitor. Try to turn, consider whether the specification of RAM and also Clock
Processor is in conformity with the specifications stated in his Box?
5. If all is okay, then in pairs of other devices such as Hard drive, Floppy Disks, CD
ROM, LAN Card and others.
6. Once installed all try to turn it on again, if there is no problem, can proceed with the process
installation.

• When you assemble your own computer right note WARRANTIES its limits, before the warranty runs out,
do not ever throw Box peripheralnya places such as Ram Box, Box MainBoad, VGA and other
forth.

Examples of problems that often occur in Computers:
1. At the time of booting, the computer displays the text "CMOS check sum error". This indicates that
stone BIOS battery was already low. Solved by replacing the BIOS battery according to the size
original.
2. The computer does not display anything when turned on, no sound coming out of the speakers.
Try checking the cable that connects between a VGA monitor. If you did not find any
damage, VGA Cardnya kemunkinannya is damaged.
3. Computer beep sound repeatedly when turned on.
RAM Check it, maybe there is dust / dirt, try off and cleaned, then in pairs again.
If still equal, replace his RAM.
4. When enabled, the hard drive indicator lights up and hold.
Possible hard drive has been exposed to BAD Sector Sector zero on it. If not so bad, still
could in the Low Level Format, then on the partition and the format, then try discandisk with surface
check
5. Computer displays messages Failur OR NON BOOT DISK SYSTEM ON DISK

This marks the Disk there is no system for the load to RAM, or hard drive has not been set
become active at the time to do the partition.
6. When do the formatting on the diskette, the message "Invalid Media or Track 0 Bad" diskette means
it has been damaged in its sector 0. Take a look at the inside of the diskette, whether existing scratches
there. When it means the disk was already damaged.
7. Computers can load up to the Windows environment, but it looks cracked when set to high
This marks the true color or VGA card is not able to display color and
maximum resolution.
8. When trying to read the contents of a floppy disk, the computer displays the message General Failur Reading Drive A,
This could be due to the Floppy Disk Drive Head dirty, or worn. Try cleaning first
by using the Floppy Disk Cleaner, if the result is the same, meaning his head was already worn out
and must be replaced.
9. The first time you turn on the display on the monitor screen blur. This indicates that the regulator Focus on
Flyback monitor was not good, usually finishing with the transplant.
10. Views on the monitor over time the more it is not clear (blurred). Same as No. 9.
11. Monitor does not display a particular color. This menadakan there is a problem in a series of RGB in the
monitor.
12. Sometimes the monitor turns itself off, or difficult when turned on. Usually there is a loose solderan
Power Supply on its part or in its horizontal section.
Computer Peripheral 13.Cara Perform Testing:

1. Mainboard
Put processor in its socket, notice the sign / pin number 1. After the then connect with the power supplay, do not forget to plug the speakers. Try to turn it on, when the beep sound from the speakers out repeatedly, it means the mainboard is still good.

2. Processor
Install the processor on the mainboard Socket Processor, RAM and VGA card if not already ON Board. Then connect with the monitor and try to power, note the display on the screen. Note whether the clock for the processor is in conformity with the one shown in his Box.

3. RAM
Similar to a test on the processor except that the note is when a computer check on the RAM. What is the capacity of RAM is in conformity with the one shown in his Box? If the computer does not do a test of RAM (computer immediately displays the capacity of the RAM), this is a sign that soon it will die of RAM. If still warranty it immediately redeem RAM.

4. VGA Card
To perform tests on a VGA Card, must first install an operating system and installed drivers for the VGA. Perform the test with a way to maximize the setting for Display Adapter (note the ability of the monitor to perform this test), if it still can be set to the maximum setting, which means that the VGA is still good.

5. LAN Card
First we must check if the OS has to recognize and install drivers for the LAN card or not. If not, we must install the driver first. Once completed then we are setting the IP for the LAN card. Here's how: Right-click on Network Neighborhood icon, select Properties. Fill in the IP addresses, eg 192.168.0.1 and Masknya Sub Net 255.255.255.0, then open the MS DOS Prompt and try pinging the IP address that you typed earlier (ping 192.168.0.1). If successful, the LAN card can be used. But when the screen displays the words "Request Time Out", the LAN card can not be used again.

6. Sound Card
First we need to install drivers for the Sound Cardnya when the Operating System Sound Card not familiar with us. After the driver installed, Sound Card should be able to function properly.

7. Hardisk
How to do a test that is by partitioning a hard drive with fdisk. Note the correct process, if there is a problem at the time of partition, the possibility of hard drive has started to Bad Sector. The next step is formatting the hard drive. Once completed, can be checked by using Scandisk or Norton Disk Doctor to check the hard drive each sectornya. Damaged hard drive that has begun, it usually will throw an error on a FAT or Directory Structur him.

8. FDD (Floppy Disk Drive)
Before conducting tests on FDD, make sure that the configuration in the BIOS for the FDD is correct. How do testnya: go to the DOS Prompt, and from there enter the command to format a floppy disk with the option / s (to add the system on a formatted floppy disk.) FDD is still good, at the time doing the formatting and transfer system, no noise is too loud. When FDD noise when the format process, this indicates that the FDD was Head of his already worn.

9. CD ROM
To do the test on CD ROM is usually done from the Windows environment, by trying to read a CD ROM disc. CD ROM which is still good, does not require a long time to initialize the disc on the disc the first time in put into the CD ROM, except that its disc is defective or dirty. Try also to test the speed of data transfer from CD ROM in a way unite the existing data on CD ROM to the hard drive. If there is a problem, such as data transfer starts to slow down in comparison with the early time data copies, there are two possibilities. The first is the optical an already weak, the second is a dirty optics. Try cleaning with Optic Cleaner, if the result is the same, then optical is already weak.

10. Monitor
To do a test on the monitor, you must have a CPU with standard specifications and the VGA card that is able to display resolutions à to monitor and 1280 x 1024 Analog àtinggi (minimum 800 x 600 for digital monitors). How to do a test that is by setting up 30 ± resolution at the maximum limit the ability of the monitor. Turn on long (2 hours for a new monitor.) When the display ± minutes for 2nd monitor and the monitor does not change, then the monitor is still worth taking.

11. Power Supplay
To do the test at power supplay, can be done by using the Multi Tester. Move your pointer switches contained in the multi-tester to number 50 in the DC Volt. Plug the red to the positive source and the black to ground.
Reference Voltage:
To Power Supplay AT:
Color Voltage Cable
Black Ground
Red 5 V
Yellow 12 V
For ATX Power Supplay:
Color Voltage Cable
Black Ground
Red 5 V
Yellow 12 V
Blue - 12 V
Gray - 5 V
Orange OK (power good)
If there is excess voltage in the measurement of more than 0.5 volts (either more or less), then the power supplay needs to be fixed or replaced.
