Sounds like more than just a coincidence.
I would get an electronic multimeter if you don't have one and check all the fuses for continuity. I think there's one or more fuses on the boards and I seem to recall what's called a thermistor in the circuitry as well. A thermistor is about the size and look of a half dollar coin with a wire running to the center of each flat side. it blows like a fuse if it gets too hot.
Also try plugging it into a different outlet to see if it makes any difference.
Beyond that, all I can suggest is to call your Gerber distributor to get some help.
