Begin by preparing all necessary materials and tools for computer assembly. Place an electrostatic mat on your worktable and wear an electrostatic wrist strap, connecting it to an unpainted part of the computer case to prevent static electricity buildup. Open the computer case by removing the side panels, consulting the manual if needed for specific opening procedures.
Before installing the CPU, check brand-specific information. Clean the CPU fan and heatsink with a brush. Lift the metal rod on the CPU socket, align the CPU according to its corner mark, insert it carefully, and push the rod down to lock it. Apply thermal compound to the CPU and heatsink, then align the CPU fan with the mounting tabs and screw it to the motherboard. Secure the fan with its rod and connect its power connector to the motherboard.
Locate the memory slots on the motherboard and align the RAM sticks. Gently push the RAM from both ends until it clicks into place and the tabs lock it. Install the motherboard by screwing standoffs into the system case, aligning them with the I/O bezel.
For hard disk installation, slide the hard drive into the hard drive bay in the system case until screw holes align, then screw it tightly. To install an optical drive, locate the drive bay (usually in the upper part of the case), slide the drive from the outside until screw holes align, and screw it tightly.
Install the power supply into its designated box in the system case, aligning the holes and screwing it tightly. Connect all internal device cables to the power supply, consulting the case and motherboard manuals for proper placement.
Connect the system unit to a monitor, keyboard, and mouse. Turn on the computer and press the key (usually Delete, F2, or F12) to enter the BIOS setup. Checking the BIOS allows you to confirm that all connected devices are recognized, indicating a successful assembly. After this, you can proceed with configuring the BIOS and installing an operating system.
