As a PC build technician, you install and repair the physical components of computers. Your duties require you to be familiar and work with both laptop and desktop computers. You may assemble computers according to a predetermined design or create custom models and configure hardware according to your employer’s needs. You use hand tools and, rarely, soldering equipment, and you ensure each component is fully powered and compatible with every other component. Some PC build technicians diagnose problems and make repairs. Your responsibilities include testing each built machine to ensure it functions appropriately.
