1 - Case
Case: the outer shell is composed mainly of
metal and plastic. Its main function is to contain and protect all components
of our computers. There are various types from basic to those with many
additional features. I advice to buy the case that best suits, but if you can
buy one with the power supply already included;
It 'a small metal box comes with one or more fans for cooling, the other
Party within PC cables come out of various kinds that are used to supply all
the computer components. Often the power supply is included in the case,
otherwise you have to get one. There are also various power supplies, 350, 400,
500 W; choose the power based on the number of attached devices, the power of
the cpu, the absorption of the motherboard and video card. On average, a good
power supply is to be 400 but if you want the best choose a 500W.
The latest computer fairs were also presented a 1000 W
power supplies, of course these objects are given to the professional or
enthusiast overclocking
Motherboard (or MainBoard)
The motherboard is a key component of our computers are
connected to it and installed all components.
It 'a plate formed by a number of electronic components.
On it houses of CPU, attach some power cables, are the sticks of ram, attach
hard drives, CD burners, DVD and CD players via special cables, also attach the
video card and other PCI cards (eg sound card).
The motherboard on the market are many, choose one that
fits the type of CPU that you want to host (check that the socket es.775, 478)
is the same CPU), having at least one or two attacks (IDE hd, mast. and read.
CD-DVD), some attachment (SATA HD), an attack on PCI-Express or AGP (video
card), some attacks and at least two PCI slots and banks of RAM;
CPU (processor)
Central Processing Unit or central processing unit: the
brain is practically in our computer that will run in record time all operators
who provide the computer, there are several types on the market (AMD, Intel,
Athlon, Duron, Sempron, PIII, PIV , Celeron): choose one that is compatible
with your motherboard (see the scoket 775 or 478) and watch as a parameter for
selecting the speed (or frequency) which is the clock speed at which the CPU
executes instructions and is expressed in GHz (2.8 - 3.0 - 3.2 - 2.4), the more
number is higher than the CPU is powerful and fast;
CPU Cooler
It 'a device composed of metallic copper, aluminum, or
both, is located right above the CPU, its function is to move away (disperse)
the heat from the CPU and to allow the continuous cooling: keeping the
temperature low, the CPU can work better and avoids the risk of melting the
same for overheating in the box if you buy the cpu fan is already included in
it, or have bought one compatible with your CPU;
Hard Drive
Hard disk (or disk) is a magnetic media enclosed in a
rectangular metal box so you can not see directly but it will seem like a
simple box, its function is to store all data on your computer, from files to
the hard drives ... programs differ in capacity, given in GB (Giga Byte), which
can range from 40GB up to 700GB or more. Choose the cut based on the amount of
data you plan to store on your computer. If you often store many pictures,
install programs or many games choose one of greater capacity. Also important
is the speed of rotation, expressed in rpm discs, which indicates how fast the
drive writes the data, the current standard is 7200 but if you want, there are
also 10000rmp! Last factor, there are two types of hard drives, the EIDE and
SATA (Serial ATA): what distinguishes them is the different type of physical
attack on the motherboard, but logically have more SATA data transfer rates;
RAM
Memory RAM (random acces memory) is considered the main
memory of the computer that provides access to data stored in any order, unlike
hard disks and other media, this type of memory stores data for use in the CPU
during 'development of processes, data that are overwritten by other final when
no longer needed: the ram is a type of volatile memory because it resets the
computer turns off. The RAM is divided into banks or modules that can have
varying sizes, ranging from 64 to 128 -256 -512 mb to 1 to 2 gb, if you have a
powerful processor and a complex operating system it will take a little more
RAM for allow operation at optimal speed of the PC, so if you have windows xp
and enough programs I recommend at least 512mb of ram. If your motherboard has
more than one slot you can put more modules of ram (a tour slot) and then
expand it later. There are various types of RAM, mainly DDR, RIMM, DIMM, the
standard most widely used of which there is currently DDR I and DDR II, the
second is the newer and faster: the former have a refresh rate of 400Mhz, the
second of 533Mhz. In addition to designating the Rams are the initials PC3200,
PC2700, so when you choose the ram first check what kind of RAM your
motherboard supports;
Optical Drive
CD-DVD Optical Drive: Optical drives are drives that can
read removable media like CDs and DVDs in various formats and send the data
contained therein to the computer. They are now a standard units that are able
to read both CD and DVD, but what counts are the formats that are able to read,
CD ± R, CD ± RW, DVD ± R, DVD ± RW, DVD- RAM, and finally the latest models are
able to read DVD ± DL dual layer dvd's famous words, the double-layer DVD
recording, which can contain up to twice the normal content of a DVD. In order
to choose the CD / DVD choose one that can read all common formats if he's the
best bets of the dual-layer DVD. Important is that you check the speed of
reading generally expressed by a number followed by "X", a 48X or 52X
is good;
Floppy disk drive
Floppy disk drive: is a unit that can read magnetic media,
the traditional 3.5-inch floppy. This type of unit is now little used to store
data because of the poor., 1.44MB, but you never know when you'll have to open
a floppy or load data on it;
Video Card
Video Card: important component of your computer, you need
to process and show the result on the screen so the user can interact with the
operating system via a graphical interface. There are two standard video cards,
which also depends on the type of attack on the motherboard, AGP 8x and PCI
Express. The latter is the most advanced and fast so if you were to make a new
bet on a PC motherboard that supports this standard. The capacity and speed of
image processing is measured by the videoram MB (VRAM) which is the memory that
the video cards to have them to process and is always measured in mb, if you
run processes that require high performance video buy a video card with enough
ram in general sufficient for normal operations 512mb.
Sound Card
Sound card (optional): The sound card is a PCI device,
that attaches to the PCI sockets, its function is to process the audio streams
into and out of your computer, attach it to the sockets of external units how
checkouts. Most motherboards currently on the market has already integrated
sound card, if you do not have to put it to hear the audio and if you already
have at your discretion you can still install a second.
Cables
Cables last but not least, check that box on the
motherboard are included all the cables for hard drives, CD / DVD player and
burner, floppy cable, and if enough other procuratevene
The Steps To Assemble the computer
First take the case, disimballatelo and open on the side
which bears the two or three screws that secure the panel, if you sometimes
have greater convenience in the assembly open both sides (when possible), once
unscrewed the screws pull the side panel toward you and you will see that you
will march;
Now switch to the motherboard that you must complete
before placing it into the case. First you have to place the CPU in its own
slot on the motherboard: lift the lever that serves as a lock for the CPU or
the entire rectangle of metal that is used to lock the CPU. Insert the CPU into
the socket called the pins (small golden metal tips) down being careful to
match the golden arrow or dot on the CPU with the sign in bay, the CPU itself
should come naturally, without difficulty, After resting on the socket, if the
effort you have inserted the wrong way.
In the figure is found that an AMD processor intel (very
careful)
Once positioned the CPU and put it back carefully lever
latch and / or covers you have to go to the cpu fan mounting, each CPU has its
own fan that is placed directly above or in contact and is blocked by the hooks
which are inserted directly into the motherboard or through a system of plastic
hooks that attaches to a mount already on the CPU, then placed the fan and
secure it; In general, first fastening system is used in the cpu socket 775,
the second CPU in the socket 775.
Once the installation is complete you have to put the fan
in the counter or sticks of ram into the slot, making sure that the part with
the gold leaf are facing the motherboard and ram it engages in the slot to
perfection (the ram is bounded three-quarters of a stop in a vertical cut edges
and, as a guide to follow the verse) to insert the RAM into the slot you have
to push out the two plastic side latches and then close them once inserted the
ram, if is properly inserted in the two locks will get stuck in the side holes
of the ram;
I remember at the moment there are 3 types of RAM: DDR,
DDR2, DDR3
Once you have completed these steps you have to prepare
the case for the motherboard: resting on the vertical part of the motherboard
inside the case and note which has holes for the screws, the board and what are
the corresponding holes on the case, then take the legs, including the box of
the motherboard and screw into these holes, then take the motherboard, and you
will see that riappoggiatela will be slightly raised and put in the screws and
screw holes: have thus fixed the motherboard.
Now you have to set hard drive, floppy drive and CD
burner, placing them in the structure and fastening them with screws.
To insert the CD / DVD burner and you have to remove one
of the houses in front of forntalini cover and insert the unit into the slot,
then fasten with screws.
To mount the hard drive you have to proceed from inserting
it into the slot until it stops and then securing it with screws inserted into
the appropriate holes.
You must then proceed by attacking all power supply cables
in their proper place and placing the communication cables between the
motherboard and peripherals.
All 'hard drives you connect the power cord sata if sata
hard drives do (in the picture you will see a sata adapter for the power supply
[not all power supplies have many SATA connections, so choose one with care];
In the case of hard drive Eide standard power cord
Then attach the cable sata hard drive and communication
into the socket on the motherboard if you have a sata hard drive
if you have an EIDE hard drive (PATA) attached to the
communication cable Eide (PATA).
Some types of cables and / or jumpers (for overclocking
and other)
The floppy drive is connected to the motherboard instead
of the floppy cable, a cable all'eide similar but slightly smaller and floppy
drive power cable is attached to the floppy.
Power cable of the cables floppyCollegate power of special
attacks on the motherboard.
If you now enter the video card and any other PCI cards
(sound).
To insert the video card is sufficient and appropriate
slot located by following the arrangement of interlocking plates inserted the
video card slot. For the sound card and other pci cards you have to do exactly
the same thing by putting them in PCI slots, usually white.
The cards you have to set them back down to the front of
the computer or with screws or with a simple joint, depends on the type of
houses so I refer you to the instructions of the same.
The only thing left to do is locate the wires that come
out from the front of the houses within the PC and connect to the motherboard
according to the scheme indicated by the motherboard manual: the cables are
power, reset, hdd led ... Once these cables properly connected the front panel
of the case work, and you can safely turn off and reset the computer directly
from it.
At this point attach the computer screen, speakers,
peripherals and see if both turns. If you start properly, you must only install
the operating system (as will appear warning you) and your computer will be
complete. If you do not turn on properly re-read the guide to try to understand
where you are wrong!
If the computer works well as part or Close the sides of
houses previously removed.
