How to build a PC

Our seven-part series on putting together a desktop computer from scratch

Building your own PC may seem to be difficult or a waste of time but it has many advantages. One of these is that your wallet will be much better off, as buying individual parts and putting them together can be significantly cheaper than buying a ready-made PC from a retail store. You can choose what parts you want, depending on what you want to use your PC for. Don’t know how to put everything together? Aren’t sure what parts you’re going to need and how much they will cost? We will run you through each step of putting together a desktop PC.

Part One: Building a PC -- Choosing your components

In the first part of the series, we guide you through choosing your components. We cover everything you need to know about motherboards, graphics, hard drives and more.

Part Two: Building a PC -- Installing a motherboard

The motherboard is the most basic part of the PC, and also one of the most important as all of your internal components will interact with it.

Part Three: Building a PC -- installing the CPU

After seating the motherboard it's time to install the CPU, or the brains of the computer.

Part Four: Building a PC -- adding RAM and cards

Part four outlines the installation of RAM (memory to run applications) and expansion cards.

Part Five: Building a PC -- connecting the PSU

What's the use of having a computer with no power supply? In part five we teach you how to connect a PSU.

Part Six: Building a PC -- inserting the drives

The next step in our seven-part series is installing your hard drives to store your data.

Part Seven: Building a PC -- configuring the BIOS

Configuring the BIOS is one of the final steps before you install your operating system of choice.

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Windows 10 / HP Spectre x360

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Mark Escubio

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

STYLISTIC Q572

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.
