It may be a long time ago and things were certainly different then but I remember building my first computer and how it annoyed me for approximately 3 years before I could afford to replace it. I have since worked in IT Support for a number of years and have built many computers for various uses.

This guide does not cover the actual building of a computer. It is more of guide to the things that may be considered before diving in and building a machine that becomes a costly and time wasting mistake.

To begin with, think about the tasks that will be commonly carried out on the computer. This will determine the type of components required for the build and also will affect the budget. A gaming computer may require higher specification components than a computer used for surfing the internet or word-processing.

Another thing that should be included in the planning stage is whether or not any existing components from a current computer will be used. This is important has there may be compatibility issues especially if your existing parts are quite old. This may also impact on some of the components you will be able to buy for the new build. For example, if you old computer contains IDE hard disk drives or CD / DVD Drives that you would like to install in the new machine then the new motherboard would need to have enough of the old connectors to support the devices. Also note that power cable connectors have changed over recent years so this would also need to be taken into account when choosing cases or power supplies. Once all existing devices including expansion cards, monitors and printers have been assessed for connection types etc it is time to move on with the planning.

A big thing to remember is the operating system. Which one will be installed? Will the new equipment and existing parts or peripherals be compatible with a new operating system version? Always check manufacturer’s websites for possible problems, device driver and software upgrades. In particular check existing printers and camera devices as they are commonly overlooked.

After considering the final use for the computer and existing components the process of researching and sourcing components and parts begins. If you are building an Internet and word-processing type pc then this is easier, there are large selections of motherboards on the market which have "everything onboard" this refers to the main component inside the computer. These motherboards have all the components fitted to the board, graphics, sound, networking are all included so separate purchases of these components are not required. These onboard devices can be disabled if required and replaced by an expansion card.If however you are building a gaming pc then your choice of parts may have more specific requirements. It may involve researching many components to determine what is required and what will be compatible with the other components.

When researching parts or components the internet and the search engines should reveal everything that is required to make the correct choices. When you have narrowed down a parts list then an internet search can prove very valuable. Visit the manufacturer's web pages in particular view the help and support facilities, try to find device drivers and software upgrades you may need these in the future. Be sure to search the web for support forums and see if any information regarding issues or recommendations other users have. The online community has a vast experience and knowledge base about building and troubleshooting computer problems.

After all this research the components can be purchased with confidence. They should all be compatible with all other devices and software and the build should be a less frustrating mission. The final computer should be more reliable with less time wasted troubleshooting incompatibilities and bugs leaving you to use your computer and increase your fun or productivity.
