  • Build on existing knowledge and experience
  • Work in the IT industry. 
  • Study in your own home and at your own pace.
  • Course Duration: 100 hours of self paced study - start at any time.
  • This course will develop your ability to independently undertake routine maintenance and to analyse faults in personal computers.

We expect anyone attempting this course will have either studied our Computer Servicing I course first, or have been "tinkering" with the insides of computers for some time. If you are an amateur who has learnt to open up your computer, and do things like adding RAM, you may not need to do Computer Servicing I first. Look at the content of Computer Servicing I, and if it all seems very familiar to you: start with this course. If it doesn't, you may be best undertaking Computer Servicing I first.

The urge to upgrade, repair or just tinker with the insides of a computer system can be quite strong in some people. A comparison can be made between working on the family car and working on the family computer. Initially both tasks might seem daunting however, with experience and a little guidance most repairs can be undertaken, hardware components installed or clock speeds souped up or adjusted for optimal performance.

For the first timer, the process can seem to be fraught with danger, and in terms of doing more damage than good it can be. If you follow a few basic steps though you should be able to work quite safely, both from your own and the computers point of view.

Before you begin to handle and work with any computer components it is strongly recommended that you wear an anti-static wrist-strap. This should be clipped onto the bare metal of the computer base. Better still; use an anti-static bench mat as well (for placing your components on). In this case, you connect the wrist-strap cable to the mat and then connect the mat to the computer’s case/chassis. The reason for such protection is that Electrostatic Discharge (ESD) can do serious damage to the PC’s motherboard and expansion cards, with the potential of rendering them non- functional.

Select a clearly defined work area, free of clutter and with plenty of room for laying out components. You will find that a computer has many parts that are quite small and quite similar in design and purpose, but will need to be replaced in an identical manner from which they came in order for the system to work correctly.

Label everything and group the various related components and screws together. The use of Plastic cups to contain smaller pieces is a very good idea.

Plan your disassembly well. Look for all attaching screws or cables. Never force the issue; if something does not want to budge or won't simply slide out, it is probably caught or still attached by something you have missed. Often, when exasperation sets in, the best ploy is to get up take a deep breath and attack the problem from a different angle.



  • You can start the course at any time.

Computer Servicing II is studied by distance learning, so you can study in the comfort of your own home.
