PROJECT TOPIC: AN INTELLIGENT TROUBLESHOOTING SYSTEM AND PERFORMANCE EVALUATOR FOR COMPUTER HARDWARE INTRODUCTION: The proposed system is meant to automate the maintenance, repair, and operations process, and free-up human technicians from manually performing routine, laborious, and time-consuming maintenance tasks. Computer systems typically include a combination of hardware and software components, application programs, System programs, processors, buses, memory, input/output devices etc. As advances in semiconductor processing and computer architecture push the performance of the computer higher and higher. More sophisticated computer software has evolved to take advantage of the higher performance of the hardware, resulting in computer systems that are much more powerful than just a few years ago. In a computer system in different parts different fault may arise. An artificial intelligence system is a computer system that emulates the decision making ability of a human expert, i.e., it acts in all respect of human counterpart. An expert system sometimes referred to as knowledge-based system is a Computer software that emulates the decision-making ability of a human expert. Artificial intelligence System based on expert equivalent to Human Brain solve problems; rather, they use knowledge which they reason about to draw conclusions
