A computer monitoring system includes a processor and sensors electrically thereto that are positioned beneath the playing surface directly below a boundary line. The sensors are connected in series to the processor such that each sensor is independently activated and generates an analog output signal when a predetermined weight limit is detected thereon. The sensors are positioned below a three-point and a free-throw line. An analog-to-digital converter is coupled to the processor and sensors that receives and converts the analog signals to digital signals. A memory includes programmable software instruction that cause the system to perform a series of operations. The processor generates and transmits audible and visual notification signals for each of the consecutive digital signals when the time span is greater than the threshold interval.
