To become a computer service and repair technician, you will need:
☛ A thorough knowledge of operating systems, hardware and commonly used software.
☛ Good communication and customer service skills.
☛ Excellent problem-solving skills.
☛ A patient and organised approach.
☛ The ability to meet deadlines.
☛ A willingness to keep up to date with IT developments.
☛ An awareness of electrical safety issues.
This is a fairly large topic but the essentials to know is understand the power supply wattage's and voltages:
☛ Have an understanding of motherboard and CPU socket types.
☛ Understand different RAM types and speeds.
☛ Understand motherboard slot types (AGP, PCI, PCI-E etc..)
☛ Understand hard drive types such as IDE and SATA and understand hard drive jumpers and their configurations.
With these skills, you need to be able to assemble a computer. I am not just talking about putting one together, but building a good one by knowing their part speeds, compatibility and possible bottlenecks.
Formatting a computer is a fairly common task for most computer technicians but its a little more than just sticking in the Windows CD during boot time and installing. You also need to know the differences between OEM, Retail, Branded, Home, Professional, Volume and Corporate Licenses.
☛ Know to setup a network with a modem, router and a few client computers.
☛ Understand how IP addresses work in a private network vs public Internet situation.
☛ A general understanding of masking/subnetting.
☛ Understand what your Gateway is.
☛ Understand how DHCP works and also know how to setup a basic computer to computer network.
☛ Understand how and when to use static IPs.
☛ Know how to forward ports.
☛ If wireless is involved, know how to apply encryption, understand signal strengths and how it can be improved.
You need to be able to remove data from a non-booting operating system by either using a boot CD and an external hard drive; or by putting the bad drive into a good system of your own and recovering it that way.
Computer technician positions may require or prefer a degree in computer information services or a similar degree. Network administration or electrical engineering are also common degree paths for this profession. While a bachelor's degree is preferable, you may find employment with an associate's degree and demonstrated acumen and experience. Continuing education may also been required within your specialization.
Many tools are needed to perform this job. A computer technician will typically need an anti-static wrist strap, power supply tester, cable crimping tool, cable tester and a variety of screwdrivers. There are several software-based troubleshooting tools offered in this field which may require a subscription for professional use. Storage devices such as an external hard drive or large USB drives often prove invaluable. Other tools may be required within specific positions and they may be listed in the job notice.
Computer technicians are expected to be disciplined and dedicated troubleshooters with a broad and deep knowledge of information technology maintenance. Technicians are able to work in different environments, from private homes to computerized corporations. Good computer technicians are polite and have strong work ethics and integrity when handling a client's property.
You need to be able to remove tough viruses like Antivirus2009 (without formatting) and understand how to use tools like Combofix, SmitFraudFix, Autoruns, Process Explorer, Malwarebytes, Superantispyware and UBCD4Win.
