To build a new computer from parts there need to be some practical precautions to be taken into consideration before the parts are assemble.
Step-by-step explanation:
To protect your computer from electrostatic discharge, do not plug in any of the part into an electrical socket before or whilst assembling.
The next thing pay attention to is the USER MANUAL attached to the computers.
There must not be any liquid or food substance it the area where the computer is to be installed.
The desk on which the computer parts will be placed must be strong enough to carry the weight of the computer.
There must also be enough ventilation in the room for more are to cool the system unit.
The computer must be cleaned and dusted regularly.
The process for assembling the parts are given in the manual and must be followed thoroughly especially with input and output voltage settings.
