Building a computer used to be a complicated process, where careful selection of delicate parts was a necessity; when that collection of components finally booted up for the first time, it was a triumphant experience.

Nowadays it's easier than ever, with clear standards of compatibility, obvious choices for performance and value, and an actual building process that’s straightforward and well documented. That said, there are pitfalls to avoid and assumptions experienced builders make that newcomers won’t know. We’ve compiled this handy step-by-step guide that will take you from a pile of parts to a working computer in just a couple of hours.

Step 1: Parts

Materials Needed:-

One (1) motherboard

one (1) compatible processor with cooling fan

one (1) compatible memory module

one (1) tower casing with power supply

one (1) graphics card (if the motherboard does not have a built-in video adapter)

one (1) compatible hard disk for storage

one (1) CD/DVD-ROM/RW drive

one (1) ps/2 or USB mouse

one (1) ps/2 or USB keyboard

one (1) CRT or LCD monitor

one (1) Philips screw driver

one (1) pack thermal paste or grease

Step 2: Maintaining Parts

When all the parts of the computer have already been selected and checked for compatibility, begin by laying all the components on a flat surface. Make sure that they are placed on anti-static sheets or wrappers (the sheets they are packaged in, for example) to avoid damage due to electro-static discharge. Also, avoid touching any leads or any exposed metal on any component.

Step 3: Placing Processor

Take the processor and carefully place it on the CPU slot of the motherboard. Take note of the correct positioning of the processor. Avoid touching any lead of the processor to avoid damaging it. Refer to the motherboard manual for the correct placement.

Step 4: Placing Cooling Fan

Apply thermal paste to the cooling fan of the processor. Spread the compound evenly on the metal surface. Install the fan on the motherboard, following the instructions on the motherboard’s manual. Take care in doing so to avoid damaging the processor. Connect the CPU fan’s power to the appropriate pins on the motherboard. Refer to the manual for the correct pins.

Step 5: Placing Motherboard

Place the motherboard in the tower casing and screw it in place. Install the back panel that came in with the motherboard on the casing. It should fit the rectangular hole at the back of the casing.

Step 6: Placing Ram

Insert the memory module in the memory slot of the motherboard. Locate this on the motherboard’s manual. Avoid touching the chips of the memory module to avoid damage. Check the slots of the memory so that it fits appropriately into the board’s RAM slot. When the memory module is properly inserted, the locks would snap to an upright position and lock the module in place.

Step 7: Placing GPU

If the board has no video adapter built in, insert the graphics card in the appropriate slot in the mother board. This may be the AGP or the PCI-e slot, depending on what components you have. A lock would also hold the card in place.

Step 8: Installing Cd/DVD Rom

Install the CD/DVD-ROM/RW drive in the casing. Screw the drive in place to secure it. Connect the drive to the board using the IDE cable that came in the package. An IDE slot should be available on the board.

Step 9: Placing HHD

Mount the hard disk in the casing. Screw the drive in place to secure it. Connect the hard disk using the appropriate cable that came in the package. This may be an IDE or a SATA cable. An available IDE or SATA slot should be available on the board.

Step 10: Connection

Connect the casing’s power, reset, and LED pins to the motherboard. The appropriate pins on the motherboard can be seen on the manual.

Step 11: Finally Made It !

Screw the cover of the casing in place.

Step 12: Attach LCD

Attach the CRT or LCD monitor power cable to the power supply. If there is no slot on the supply, then the monitor plugs directly into an outlet. Connect the VGA or DVI cable of the monitor to the graphics port of the system. This may be the built-in port or the port of the installed graphics card in previous Step
