A PC support technician is a professional who does troubleshooting, maintenance, installation and repairs of computer hardware and diagnoses software issues. The professionals are usually available to provide technical assistance and support to any employee using a PC for work. The main areas of focus are upgrading computer systems, removing viruses, ensuring network safety, installing new hardware and collaborating with other information technology technicians.

The technicians are also often known as help-desk technicians. They will occasionally travel to off-site locations to resolve PC problems. It is common practice that the technicians are always available to give instructions and advice to users on how to resolve their PC problems. Apart from getting involved in the hardware and software problems, the support technician also troubleshoots and repairs other peripheral equipment such as printers.
