Building a computer with your own hands
Installing the processor and the motherboard.
Before you begin building the computer yourself, let's look at the figure below. It presents all the main components from which the computer will be assembled by our own hands (with our hands) :)
Briefly go through the individual components of our "experimental", so that the assembly of the computer with our own hands seemed to us more holistically.
- Under the number "1" we have a motherboard
- number "2" - external PCI Express graphics card
- "3" - cooling system (aluminum radiator and cooler for heat dissipation)
- "4" - the processor itself for socket (socket) LGA 775
- "5" - two DDR2 memory modules
- "6" - IDE cable (for connecting a hard drive or CD-DVD of the old standard)
- "7" - optical DVD-ROM drive
- "8" - computer power supply
- "9" - hard drive (hard disk) standard SATA
- "10" - a cable (for connecting a hard drive or CD-DVD standard SATA)
- "11" - floppy disk (drive) and its data cable
Naturally, all this "economy" must be packed somewhere. For this we need a good case for the computer .
The computer is assembled by the hands in the following sequence: first we install (actually screw) the motherboard into our case, install the processor and its cooling system into it, and then we connect and fix to this "foundation" the other necessary elements.
Another link, which in a separate window schematically shows the sequence in which the computer should be assembled.
So, at the initial stage of the self-assembly of the computer, we need to install the motherboard in the chassis. With regard to it there may be such recommendations: the case must be large enough so that we can freely install all the components that we need.
The board is attached to it using screws that are screwed into special fastening bushings (metal hexahedrons). They come complete with a casing.
The bushings are screwed into special holes on the rear wall of the computer's system unit (on the inside of its right side wall), on top of which is placed the motherboard and is attracted by screws.
Hexahedrons are needed in order to form a gap between the board itself and the metal surface of the system (in order to exclude the possibility of electrical contact between the elements from the back of the board and the case). Such a contact may well cause short circuit (short circuit) and disable the electronics. The more sleeves you can use, the more reliable will be the fixation (see the number of mounting holes on the body and the board itself).
Tip 1: Remember, the fixing bushings for the motherboard should come complete with the computer case. If you buy a case, then only with them. This is important because these fasteners are different in height and differ in the width of the thread at the base. With others, you simply can not install the board!
Tip 2: If you plan to change the motherboard (buy it from the hands or in the store), then be sure to check if it comes with a panel with holes for the connectors? The panel will need to be installed on the back of the computer when you install the computer yourself. Pay attention to the photo below:
Note that the location of the holes for the connectors for each batch of cards is different and if you do not sell the panel corresponding to the motherboard at once, it will not be easy to get it separately afterwards.
The panel is installed in a specially designated place for it. This must be done before the motherboard is placed in the case.
Correctly orient it in relation to the main connectors and install by pressing your fingers lightly. The plug must be firmly seated and fixed with a characteristic click.
Below you can see a video that demonstrates the whole process:
We continue assembling the computer with our own hands. After we have fixed the motherboard in the case, we need to install the CPU in the slot (socket) of the motherboard. Let's look at the picture below and comment on some points.
The order of installation in the slot is the following: press down and bend the clamp to the side (indicated in the photo above at number 2). To do this: click it out from under the special hook (in photo number 1), raise the metal frame (number 3), which fixes the processor in the connector. After that, we only need to install the CPU itself (indicated by the number 4).
Attention! Well look at the processor and determine from which side it has a "key" (specially cut off on one side of the corner or two small grooves on the sides). The socket has the same corner or protrusions in the appropriate places. When installing the processor in the socket, they must necessarily be combined with each other.
When the installation is complete, we repeat all the steps in the reverse order: put the fixing cover on the processor (No. 3), lower (already with a certain force) the pressing metal rod (No. 2), move it slightly to the side at the lowest point and pass under the special hook on the side №1.
On how to install the processor of the old PGA sample (believe me, it needs to know) see the video below:
In the process of self-assembly of the computer, we need to be able to install a cooling system (radiator with a fan). It should be noted that now we are installing a cooling system for the product from the company "Intel", in the case of the company "AMD" it looks a little different.
In theory, it looks like this: at four corners from the processor slot there are special holes in the motherboard, it is through them that the whole air cooling system is fixed.
Accordingly, the radiator has four special plastic clamps, which, when pressed, press the heatsink to the processor and, incidentally, fix the entire structure on the motherboard.
Here's how the close-up of the cooling system for our processor, which we just installed:
And this is one of its fixatives on the board close-up and we snap it.
Pay attention to the photo below:
Do you see the grooves (grooves in the form of grooves) on each of the four plastic clips? The position when the recesses are located perpendicular to the fins of the radiator correspond to the closed state of the latch-lock (in the photo above all latches are closed). It is in this position that they all must be before installation on the board! Remember this!
The arrows indicate the direction in which you need to turn (you can make it with a screwdriver) the latch to move it to the open position.
Tip: After placing the radiator clamps strictly above the holes around the landing slot (you need to make sure that the plastic points of the fasteners drop a little in them), it is necessary to simultaneously press the two clamps diagonally from each other (until they click and securely fix them in the board). Then we carry out the same procedure for the two remaining clips. All! Cooling system installed!
It is much easier to show the entire process in a small video once than describe it in words, so watch the video below:
If there is a need to remove the cooling system, then simply translate all four latches into the "open" position and pull the structure onto yourself (it will be removed quite easily).
некоторым людям удобнее устанавливать систему охлаждения компьютера до того, как материнская плата будет закреплена в корпусе. Tip: Some people find it more convenient to install a computer cooling system before the motherboard is fixed in the casing. So it is possible to visually see what and where it snaps into place, and measure the strength of the applied effort to securely fix the elements.
The design for attaching the cooling system to processors from the company "AMD" is somewhat different from what we can see in the products from "Intel". It consists of two parts: a plastic frame-base, securely fixed around the processor socket, and a radiator with a fan, which are fastened (snapped) on this frame. Here, for example, what it looks like for the AM3 processor socket:
As you can see, with this approach, the force of the pressure pressure from the radiator is transmitted directly to the plastic substrate (frame) and then evenly distributed over the textolite of the motherboard itself.
By the way, when removing cooling systems from motherboards under the control of Intel processors, it is often necessary to observe how the very basis of the motherboard (textolite) has visually noticeable curvature (from the constant pressure on it of the cooling system radiator), which is attached directly to the board itself . This is bad and could potentially lead to micro-cracks at the very core of the motherboard.
Building a computer by yourself, in particular, installing the processor and the motherboard is often associated with installing third-party cooling systems on the processor, which can have a mass of half a kilogram, or even more! In this connection, in order to prevent the deflection of the motherboard in the place where the motherboard is fixed, a special metal cross is placed in their set, which is located on the back side of the board (under the processor).
This additional fastening is called the word "Backplit" (Backplate) and it serves, as we have already said, to remove unnecessary physical strain from the motherboard. The only nuance of this design is that it must be installed before the board is fixed in the computer case.
Do not forget: a properly installed cooling system avoids overheating of the processor in the future!
When assembling the computer, we need to remember to do one more thing: from the cooling fan there is a small (3 or 4) pins that feeds the motherboard to the fan so that it rotates and dissipates heat. We need to find the appropriate connector on the board (usually 3-4 pins next to the processor socket) near which there is an inscription "CPU_FAN" and connect our power cord to it.
The most important components and cooling system are installed. Now we need to install all the remaining devices. And since computer assembly by oneself is quite a responsible and painstaking task, it requires attention and caution. Well, we finish this manual on this note, we hope that it turned out to be useful and interesting for you.
