If you look at your breaker panel, there will be a column of breakers on the right and one on the left. Each column is a different phase. So it could be a problem if you had an outlet in your room connected to a circuit coming from the left column and a different outlet on a circuit on the right side and then you connected your components to both of those outlets, willy nilly. The power sine waves are shifted relative to each other (180* I think) so that they don’t line up...
Have you checked the connections in the panel (if you’re knowledgeable enough to do this without killing yourself)? It seems it could be a loose/dirty neutral or ground within the service itself.
I second the idea that it would be possibly useful to know which phase the three different locations are on. Particularly if location 1&2 are on a different phase than 3.
