Upgrading a Computer

Computer industry is a fast changing industry. A new technology is almost introduced
daily. Therefore, as a computer technician it is your responsibility to replace the existing computer components with newer components to make the computer up to date. This is called computer upgradation.

You usually need to upgrade the computer to improve its performance and capabilities like memory, speed, etc. Upgrading is a cost-effective way to improve the technology and increase the productivity when the budget is highly constrained.

Preparing to Upgrade

Before you actually start upgrading a computer, you need to prepare yourself for the
upgradation so that the upgradation can be performed smoothly. This also ensures that if something goes wrong, then you can return the system to the state that it was prior to the upgradation.
The following checklist will help you to determine what all things are required before performing the upgradation:

Assemble the required toolkit
Collect the required documentations
Create a backup of all data
Have a copy of the original Windows installation CD
Set a system restore point (only in case of Windows Me/XP)
