Computer Servicing II

STUDY COMPUTER SERVICING AT HOME

BUILD UPON YOUR EXISTING HARDWARE SKILLS WITH THIS COURSE

Why choose this course?
This course covers more into the hardware diagnostics, fault analysis. It also covers software trouble shooting etc. This course expands on and continues from the basics covered in Computer Servicing 1.    It will, along with Computer Servicing III, help develop your ability to independently undertake routine maintenance and to analyse faults in personal computers.

Pre-requisites: Computer Servicing I (or some experience, or equivalent).
