Although it seems an incredibly difficult task, build a computer from scratch is a task that if we start with patience and a little knowledge, we can do it without any inconvenience, although our knowledge in computers is basic.
Mounting a PC from scratch brings us a lot of benefits. In principle the costs. There is no doubt that build our own computer to be significantly cheaper than buying one pre-built. In addition with the same budget we can access a truly superior computer than those offered in stores, and we can even choose to purchase high quality components. It is why in this article we will find all the necessary steps to build a PC, including safety instructions and tools needed to undertake the task.
Before beginning, we must ensure we have the right tools for the task. Fortunately, tools are not difficult to obtain, since it most likely is that we have at home.
- Screwdrivers (multiple sizes and types)
- Some additional screws
- Cleaning cloth
- Isopropyl Alcohol to clean
- Long-nose pliers
- A flashlight (optional)
Once you have collected necessary, it is time to start.
Step 1: The power supply
In principle, if we have acquired a cabinet that did not include power supply, the first step is to mount the power supply case to the chassis of the cabinet. This we must do considering that the fan points away from the box, to the rear of the cabinet, and that the color cables facing inside of the box. Once placed, it must be fastened with screws.
Step 2: Install the processor
Although it is possible to install the processor once the motherboard be attached to the chassis of the cabinet, it is best mount the processor before fixing the motherboard on the chassis
First thing we do is identify the socket where the processor which is readily detectable be located, as usually it is large and has several circular holes, in addition to the indication of the acronym ZIF.
The correct location of the processor will be defined according to the alignment of the slot. The CPU has a mark in one of its corners that allow us to put the processor correctly. Obviously this mark must exactly match the one that has the socket.
Carefully put the processor on the socket, and without exerting much pressure we insert the pins of CPU into the slots socket. For this we do not force, just let the CPU “fits” into the socket. In the event that this does not happen, possibly are due to the processor has some of its bent pins, which can straighten carefully with the help of a flat screwdriver.
Then, move down the socket lever, for that the processor is firmly attached to the motherboard.
Once the task is finished, and only if the processor does not include factory sink, we mount one on the CPU, through the anchors that includes the socket. It is likely that before placing the sink, we need distribute thermal paste with fingers, carefully to form a thin film on the processor, avoiding that too much pasta to accumulate, and then just be able to place the sink.
Anyway it is always advisable to purchase a processor that includes a sink factory, in order to avoid mistakes of beginners.
Step 3: Mount the motherboard into case
The following will mount the motherboard to the chassis of the cabinet, for that, we only need align properly the motherboard to the holes including in the chassis, and then fix it with the screws that come standard with the cabinet.
We must ensure that the various connectors are properly located, in order to subsequently be able to mount the plates necessary for our computer.
Step 4: Install RAM modules
RAM modules can be mounted before or after placing the motherboard in the chassis of the cabinet. That depends on the decision of each.
Once we identify the banks for RAM, we must carefully place each module on them and push it slowly and without exerting force until we hear a click.
That sound will let us know that RAM is installed correctly.
Step 5: Attach cables
Before continuing to introduce components, it is advisable to connect some cables to the motherboard. In principle we must connect the motherboard to the power supply.
It is also convenient connect the cables on the front panel of the cabinet, both the power and reset buttons, as LEDs, USB and other ports. To do this it is best to resort to the motherboard manual, which states clearly how they should be connected according to the motherboard model.
Step 6: Expansion cards installation
If we have decided to include some extra PC board, as it can be a video card, a Wi-Fi or Ethernet, this is the precise moment to mount.
To do this we must identify the PCI-E, PCI or AGP slots in which the card must be mounted. It is placed so that the pins match with the connector, and then we pressed without force until hear the click that indicates that has been fixed in place.
Step 7: Install devices
The following will connect the devices, and first will be the hard disk. This should be placed on the support having the chassis, and once properly secured with the appropriate screws, initiate the connection.
Notably, all storage devices have two connections, one to the motherboard and the other to the power supply. We must then connect the power cord from the power supply to the hard disk slot, and then connect the cable SATA drive to the motherboard.
Basically, in the case of the optical means we should perform the same steps.
Step 8: Before closing, sort all the cables
Patience, already almost done. Before closing the cabinet, we must fix and accommodate cables that may have become loose. To do nothing better than use elastic bands or seals, which besides good aesthetics, will provide good security to internal components.
We take a last look and a final check to verify that all cables and connections are properly adjusted, and we can put the cabinet tops.
Step 9: The decisive moment
It only remains now connect peripherals to the CPU, i.e. the monitor, keyboard and mouse, as well as the cable for electrical power.
If all goes well, and the team on, just subtract configure the computer and begin installing the operating system that we have chosen.
