This may sound far fetched so FWWIW, Do you live in an area experiencing winter? Is the machine near a cold area, outside wall or window? At times simple thermal states can cause poor circuit continuity just because the metal is cold. Years of crud such as cigarette smoke, cooking fumes etc can infiltrate the mechanical structure of the connection and be a factor also Long time readers here know I preach the practice of looking at the simple things first. Dirty, poor or loose connections are the place to look first when talking I / O. Anyone who ever had a truck ignition fail on a frigid day knows the fragility of circuit continuity is stressed further by temperature differences. So keep thinking along the lines of the " overpowered " idea for now. But if that does not lead to a fix of the problem try cleaning and tightening the connection.
