How To Build A Computer

Hello and welcome to the DIY All Day guide on how to build a computer.

Let us start by saying: there is nothing more frustrating than trying to do something new with an incomplete set of instructions.  We at DIY All Day feel your pain.  Other guides are incomplete, outdated or worse—both.  That’s why when we set out to make our guide on how to build a computer we wanted to make it the best on the net.  It is our hope that with this guide that even someone with very little experience can get their parts ordered, assemble their system and handle any troubleshooting that may be required to get the system up and running.

We updated this guide periodically following any major hardware release.  Check the “Last Updated” date at the top of any article to see when it was last revised.
