ABSTRACT
This research study examined automated system for troubleshooting personal computer (PC), using Digital Center, Akwa Ibom State Polytechnic as a case study. The system was necessary to develop because personal computer users encounter problems and they can only solve this problem with the help of a human expert. Findings revealed that many people do not know how to maintain their computer systems due to limited knowledge on how to troubleshooting and the systems eventually break down. This can also be traced to the absence of an expert system that will help users fix system issues and troubleshoot PC problems. A software system has been developed to address this problem. The programming language used is visual Basic 6.0 and the codes have been source-listed.
