Build a computer with your own hands

How to build a computer? This question is asked by those who have not had experience assembling a computer, but decided to buy a computer in parts. In reality, manually assembling a computer is a matter of ten minutes.

Of course, assembling a computer requires components that you must have already purchased.

It should be mentioned that this article about assembling a computer is not always useful (who knows what computer manufacturers will come up with), but in most cases everything should turn out fine.

So, the components are removed from the packages and lie on the table, waiting for assembly. Let’s get started

We collect the computer system unit.

We take the motherboard (motherboard), we connect the processor with a fan. Here you need to act on the manual of the motherboard, because the different motherboard manufacturers have different processor insertion algorithms.

Well, if the processor comes with its brand fan (the so-called boxed version), this gives a guarantee of the reliability of the entire design of the mounting of the radiator and the fan to the processor. The processor itself is usually inserted easily, but you need to be careful with the fan. Some models of AMD processors (Intel doesn’t have this) can literally crumble if you press the processor too hard with a heatsink. Act on the manual, then you need to observe all the points.

Next, insert the memory modules into the motherboard. Now most components have the so-called ‘foolproof’. This means that some part cannot be inserted incorrectly or into the wrong slot. This also applies to modern RAM. We take the module, insert it firmly until it stops and fix it with plastic holders on the sides of the slot. Holders must fit into the clippings on the RAM module. If done correctly – the ‘RAM’ will hold tight.

Moving on to the next step of assembling a computer. We take the motherboard with the processor and RAM inserted into it and insert it into the case with the cover removed. The case must be pre-prepared – all metal patches on COM, LPT, USB ports and expansion cards are removed. The motherboard and case are standardized, so in the overwhelming majority of cases, its place in the case is immediately visible. The motherboard must be screwed to the side wall of the case.

After inserting the motherboard, you need to connect all the wires – power cables to the board and the processor, speaker, power_led, reset cables, etc. The position of the necessary jumpers should be indicated in the manual.

Next, the next item on the computer’s assembly is the insertion of expansion cards (if any) – a video card, sound card, modem, etc. If you do not need to insert cards (video, sound, etc. integrated) – you can skip this item. Video cards are inserted into a special AGP connector, which is signed with the corresponding letters on the board. As already mentioned, it is almost impossible to insert something wrong. The remaining cards are inserted into the PCI slots. If the question arises, which one to insert into PCI-1 or PCI-3, I say – this does not matter much for modern motherboards, but in order to improve performance, it is still better to insert one by one – into PCI-1, then into PCI- 2, etc.

Next, insert the hard disk (s), CD / DVD-ROM / RW, Floppy-drive in the appropriate compartments in the case so that the front side of the devices looked out. We connect the devices to the power supply unit with the appropriate cables and to the motherboard with loops. Remember that it is desirable to HDD and CD / DVD-ROM is better to hang on different cables. For example, HDD on IDE-1 Primary, and DVD-ROM on IDE-2 Primary. If there is also a CD-RW, then it is better to hang it on the IDE-2 Secondary on the second branch of the loop. Floppy connects with its own twisted loop.

Now you can say the computer is assembled. It remains to connect external devices. We connect the monitor to the video card, speakers – to the sound card. Next, connect the mouse and keyboard to the PS / 2, COM, or USB port (it depends on their interface).

Now you can connect the power cables of the system unit and the monitor. The housing cover can not yet close. Connect the cables – turn on the computer. If you see on the monitor inscriptions BIOS – then everything is fine. It remains to close the lid, configure the BIOS and start installing the operating system.

If nothing happens after pressing the button, check all power cables for correct and reliable connections. See if your power supply fits to the motherboard at all. If, after switching on, the fans start working, but the speaker makes some sounds, then look at the manual of the motherboard what these sounds mean and how to fix the problem that caused them.
