Computer Assembly (Launch Chapter)
Assembling computers is a large part of a technician's job. As a technician, you will need to work in a logical, methodical manner when working with computer components. As with any learned trade, computer assembly skills will improve dramatically with practice.
This chapter details the steps used to assemble a computer and to boot the system for the first time. These are some important points to remember:
Computer cases come in a variety of sizes and configurations. Many of the computer components must match the form factor of the case.
The CPU is installed on the motherboard with thermal compound and a heat sink and fan assembly.
RAM is installed in RAM slots on the motherboard.
Adapter cards are installed in PCI and PCIe expansion slots on the motherboard.
Hard disk drives are installed in 3.5 in. (8.9 cm.) drive bays located inside the case.
Optical drives are installed in 5.25 in. (13.34 cm.) drive bays that can be accessed from outside the case.
Power supply cables are connected to all drives and the motherboard.
Internal data cables transfer data between the motherboard and the drives.
External cables connect peripheral devices to the computer.
Beep codes signify hardware malfunctions.
The BIOS setup program displays information about the computer components and allows the user to change system settings.
Computer components require periodic upgrades and replacement parts.
Additional hard drives can provide fault tolerance and the ability to install additional operating systems.
