INTRODUCTION

BACKGROUND OF THE STUDY

Troubleshooting is the act of detecting and mending faults be it a hardware or software facility.  To be good trouble shooter one needed to understand a system better than the average person.

Maintenance is the performance of “prevention or remedial maintenance in order to prevent incipient hardware faults or to correct a hardware fault that has occurred”.  We therefore define computer and other hardware maintenance as the prevention and correction of faults in the system or as knowing fault that has occurred or as knowing fault that has occurred or that fault can occur and taking steps to ensure that the fault is eliminated.

The impact of engineering age is tremendous and its arrears of application are increasing geometrically.  It is believed that the information revolution will radically change the nature and quality of engineering work in the near future.

Some of the most exiting arrear of the information technology includes.

Office automation and computer publishing

Just-in-time (J.I.T) production techniques to reduce cost and improve quality.

Electronic shopping and electronic funds transfer

Computer controlled commuter train system

Decision support system (DSS) that facilitate real time control of making under battle field condition typically characterized by uncertainty

Computer aids to the handicapped including intelligent implants and experts for medical diagnosis.

Computer aids instruction (CAI) and aided manufacturing.

Due to all these mentioned arrears of computer application and more, computer has now been accepted and used by so many organizations, by individuals for various purposes.  It is believed that computer is an agent, which improves productivity, enhances competition.

It is however worthy to not that 75% of all computer application generate documented information.  This is why it is said that had copy is the spice of information.

STATEMENT OF THE PROBLEM

When computer systems malfunction, it is often difficult tracing the causes of such malfunctions with respect to identified symptoms.  Often, some of these faults are so minor that virtually every user is supposed to be able to handle them effectively without having to undergo the rigours of finding maintenance experts.  In many occasions, the defects are perfectly eliminated by clearing the edge connectors and resisting the plugs and pc interface cards.  Some diagnostic software such as Qapuls could also help in locating the causes of the problem.

However, the need for a reliable maintenance service cannot be over emphasized.

Since it is necessary for effective performance of any computer system.  Also it is pertinent to observe that there is many other preventive maintenance procedures that can be duly appreciate by the user which could minimize pc failure.  This project has been designed and preventive maintenance in a “DO IT YOURSELF FASHION.  It as well provides most of the salient information necessary to troubleshoot Computer systems.
