Power supply in HP slimline s7310n


It sounds like the CPU is over heating. It probably has poor ventilation. Unplug the unit and open the side panel. Carefully vacuum all the dust inside. Be careful not to damage any electronics. You can use a small brush to loosen the dust before vacuuming. Good luck!
