Last night I removed the Q40 completely from its case and set it all up on the table. It ran all evening (about 3.5 hours) with not a flicker of interference on the monitor. Not even when I picked up the mainboard, or prodded (gently) the video RAM chips. This suggests that when the mainboard is mounted in the case, with the I/O card screwed onto the back panel, the geometry of the case is putting the board under sufficient strain to move one or more chip pins in their sockets enough to break connection. There were no metal objects trapped between the mainboard solder side and case.
