在动手组装电脑前，应先学习电脑的基本知识，包括硬件结构、日常使用的维护知识、常见故障处理、操作系统和常用软件安装等。
Preparation of accessories before installation
Installation of the computer to have their own plans, do not blindly compare, according to the actual need to buy accessories.
Such as the purchase of the chassis, pay attention to the rationalization of the internal structure, easy to install, the second should pay attention to the beautiful, color and other accessories to match. Generally should choose vertical chassis, do not use the eliminated horizontal chassis, especially the chassis power supply, 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 the use of 300 W power supply should be selected according to need.
In addition to the chassis power supply, in addition to the need for accessories generally have a motherboard, CPU, memory, graphics card, sound card (some sound cards come with the motherboard), hard disk, optical drive (VCD optical drive and DVD drive), floppy drive, data lines, signal cables and so on.
In addition to the machine accessories, you also need to prepare to use the screwdriver, sharp-nosed pliers, tweezers and other tools.
Additionally, it is necessary to prepare the room for the power plugs before the installation
Basic steps for installing a computer:
When assembling a computer, you should follow the following steps methodically:
(1) The installation of the chassis is mainly to disassemble the chassis, and the power supply is installed in the chassis.
(2) Motherboard installation, installing the motherboard on the chassis motherboard.
(3) CPU installation, insert the required CPU in the motherboard processor socket and install the cooling fan.
(4) Memory stick installation, insert the memory stick into the motherboard memory slot.
(5) For graphics card installation, select the appropriate slot according to the graphics card bus.
(6) Installation of the sound card, the mainstream sound card in the market now is mostly a PCI slot sound card.
(7) Drive installation, mainly for hard disk, optical drive and floppy drive installation.
(8) Connections between the chassis and the motherboard, i.e., various indicator lights, power switch lines, PC speaker connections, and hard disk, optical drive and floppy drive power lines and data lines.
(9) Cover the chassis cover (theoretically, after the installation of the host, it is possible to cover the chassis cover, but in order to check the problems thereafter, it is best to leave the cover on, and wait until the system is installed).
(10) The installation of input devices, connecting the keyboard and mouse integrated with the host.
(11) Installation of output devices, that is, the installation of the monitor.
(12) Re-check the individual wiring again, ready for testing.
(13) Power up the machine, if the monitor can be displayed normally, indicating that the initial installation has been correct, this time into the BIOS for the initial setup of the system. After the above steps, the general hardware installation has been basically completed.
