PHP editor Youzi brings you detailed steps for computer host assembly, so novices can easily get started! Learning host assembly can not only save assembly costs, but also gain a deeper understanding of computers. Please continue reading the following content!

Preparation before installation

Before assembling the computer, you should first learn the basic knowledge of the computer, including hardware structure, daily maintenance knowledge, common Troubleshooting, operating system and common software installation, etc.

Preparation of accessories before installation

You must have your own plans for installation, do not blindly compare, and purchase accessories according to actual needs.

When purchasing a chassis, you should pay attention to rationalizing the internal structure to facilitate installation. Second, pay attention to the appearance and matching the color with other accessories. Generally, you should choose a vertical chassis instead of the obsolete horizontal chassis, especially the power supply inside the chassis, which is related to the stable operation of the entire computer. Its output power should not be less than 250 W. Some processors also require 300 W. The power supply should be selected according to needs.

In addition to the chassis power supply, other required accessories generally include motherboard, CPU, memory, graphics card, sound card (some sound cards come with the motherboard), hard disk, optical drive (including VCD optical drive and DVD optical drive), floppy drive , data lines, signal lines, etc.

In addition to machine accessories, you also need to prepare screwdrivers, needle-nose pliers, tweezers and other tools to be used.

In addition, before installation, power plugs, etc. must be prepared indoors. These contents have been described in Chapter 1, Section 1.4.

Basic steps for installing a computer

When assembling a computer, you should follow the following steps in an orderly manner:

(1) The installation of the chassis mainly involves disassembling the chassis. Seal it and install the power supply in the chassis.

(2) Installation of the motherboard, install the motherboard on the chassis motherboard.

(3) To install the CPU, insert the required CPU into the motherboard processor socket and install a cooling fan.

(4) To install the memory module, insert the memory module into the motherboard memory slot.

(5) For the installation of the graphics card, select the appropriate slot according to the graphics card bus.

(6) Installation of sound card. Most of the mainstream sound cards on the market now are sound cards with PCI slots.

(7) Driver installation mainly focuses on hard disk, optical drive and floppy drive.

(8) The connection between the chassis and the motherboard, that is, various indicator lights and power switch wires. The connection of PC speakers, as well as the connection of power cables and data cables of hard disk, optical drive and floppy drive.

(9) Close the chassis cover (Theoretically, you can close the chassis cover after installing the host, but in order to check for future problems, it is best not to cover it first, and wait until the system is installed. cover it later).

(10) Installation of input devices, connecting keyboard and mouse to integrate with the host.

(11) Installation of output devices, that is, installation of monitors.

(12) Recheck each wiring and prepare for testing.

(13) Power on the machine. If the monitor can display normally, it means that the initial installation has been correct. At this time, enter the BIOS for initial system settings.

After performing the above steps, the general hardware installation is basically completed, but to make the computer run, the following installation steps are required.

(14) Partition and format the hard drive.

(15) Install the operating system, such as Windows 98 or Windows XP system.

(16) After installing the operating system, install drivers, such as graphics card, sound card and other drivers.

(17) If the hardware is faulty after 72 hours of baking, it will be discovered during the 72 hours of baking.

The process of assembling a computer

For people who don’t have much contact with computers, they may feel that “installing” is a very difficult and mysterious task things. But in fact, as long as you install it yourself, you will find that it is nothing more than that (of course, you'd better have a general understanding of the various accessories of the computer first). After the preparations for assembling the computer are ready, the actual operation of assembling the computer begins.

(1) When you open the outer packaging of the chassis, you will see many accessories, such as screws, blanks, etc.

(2) Then take off the casing of the chassis, and we can see the drive bay used to install the power supply, optical drive, and floppy drive. Many cases do not provide a dedicated bay for the hard drive, which can usually be installed on the floppy drive bay.

The entire frame of the chassis is made of metal. It includes a five-inch fixed frame (can be used to install optical drives and five-inch hard drives, etc.), a three-inch fixed frame (can be used to install floppy drives, three-inch hard drives, etc.), and a power supply fixed frame. Rack (used to fix the power supply), bottom plate (used to install the motherboard), slot (used to install various plug-in cards), PC speaker (used to make simple alarm sounds), wiring (used to connect various signal indicators) As well as switching power supply) and plastic feet, etc., as shown in Figure 11.1 (the picture here has the power supply installed, but in fact the newly opened chassis does not have the power supply installed).

l Drive Bay. There is a baffle in front of the drive compartment, which can be removed when installing the drive. The well-designed plastic baffle on the front of the chassis uses a plastic barb connection method to facilitate disassembly and reinstallation. There is usually an iron baffle inside the chassis that can be removed at one time.

l The blank behind the chassis. The bracket at the back of the chassis is the bayonet on the rear panel of the chassis. The motherboard's keyboard port, mouse port, serial and parallel port, USB interface, etc. must be connected to peripherals through the holes in this bracket.

l Signal line. Underneath the drive bay, we can see the leads leading from the chassis panel to the Power and Reset keys, as well as some indicator lights. In addition, there is a small speaker called PC Speaker, which is used to sound prompts and alarms. There are corresponding sockets on the motherboard.

Some chassis have a small white plastic box at the bottom, which is used to install the chassis fan. The four sides of the plastic box are designed with bayonet holes. You only need to snap the fan into the box. Some larger chassis will also reserve positions for the second and third fans of the chassis.

You only need to snap the fan into the box. Some larger chassis will also reserve positions for the second and third fans of the chassis.

11.2.2 Installing the power supply

The location for placing the power supply in the chassis is usually at the upper end of the rear of the chassis. There is a screw hole on each of the four corners at the end of the power supply. They are usually arranged in a trapezoidal shape, so pay attention to the direction when installing. If installed upside down, the screws cannot be fixed. You can first place the power supply on the power supply bracket, align the 4 screw holes, and then tighten the screws.

When installing the power supply into the chassis, be aware that the power supply is usually installed in reverse, that is, upside down. Just align the screws on the power supply with the holes on the chassis and tighten the screws.

Tips: There is a principle when tightening screws, that is, do not tighten them first, wait until all the screws are in place, and then tighten them one by one. The same goes for installing certain other accessories, such as hard drives, optical drives, floppy drives, etc.

11.2.3 Installing the motherboard

There are many holes on the side panel of the chassis, which are used to fix the motherboard. There are some mounting holes around and in the middle of the motherboard. These holes correspond to some round holes at the bottom of the chassis and are used to fix the motherboard. When installing the motherboard, you must first install positioning screws in the holes at the bottom of the chassis. (Positioning The screw slots are selected according to the type of motherboard. If appropriate, one or two plastic positioning cards can be placed instead of metal screws).

Then lay the chassis down, install the copper expansion screws on the motherboard bottom plate (also aligned with the screws on the motherboard), and then place the motherboard on the bottom plate. At the same time, pay attention to aligning the I/O interface of the motherboard with the corresponding position on the back of the chassis (the position pointed by the arrow in the picture). The peripheral interface of the ATX motherboard should be aligned with the corresponding baffle hole on the back of the chassis.

Note : The keyboard port, mouse port, serial and parallel port and USB interface of the motherboard should be aligned with the holes of the cover on the back of the chassis. The motherboard should be parallel to the bottom plate and must not overlap, otherwise it will easily cause a short circuit. In addition, there are printed circuits for signal lines near the screw holes on the motherboard. When connecting to the chassis bottom plate, be careful not to short-circuit the motherboard with the chassis. If the motherboard mounting holes are not insulated, they must be insulated with insulating washers. It is best to fix one or two studs on the chassis first, usually near the keyboard jack (AT motherboard) or I/O port (ATX motherboard). When using a pointed plastic card, the pointed end must be on the front of the motherboard.
