Another computer on the bedroom circuit, that's about a 100-200 watts tops if it were on, which I don't think it was. I did notice the bedroom circuit is right above/below the living room circuit in the breaker box, so I attributed it to the breaker location within the box, and the fact the PVRUSB2 29061 was no longer working. On other circuits, there's an electric kitchen range which I did operate just as the other two circuits tripped. Also have a septic pump and water pump which *might* have been operating at the time, again separate circuits/breakers. Not too worried about it now, as I'm pretty sure it was the old PVRUSB2 29061 power supply. Nothing else could really explain such a scenario, unless the grid took a spike. Also well grounded here. One exterior perimeter ground, and one on the basement ground water well pipe. Also another separate ground rod for the antennas. ;-) Shrugs.
