You can learn the computer repair skills at a technical school, but many computer technicians are self taught. Getting a computer job requires several skills. You need to know each component of a personal computer, including peripheral devices such as printers. Installing drivers, preventive maintenance and part replacement are all essential skills. You'll need to know how to install Microsoft Windows® including how to fix damaged installs and recognize what a clean install looks like. Virus protection and removal and data recovery from a damaged non-booting operating system will be necessary.
