Gawd, that frosts my balls when I get a tech support person on the phone that can barely speak english
Given your power supplies that died, Bluemoney has a good idea. I'd get that circuit checked out...or at the very least, put a UPS on your systems to 'condition' the power. The UPS will probably also give you an idea of how dirty that circuit is if it's constantly going off. I had to re-adjust my UPS here in Florida to keep it from screaming constantly. Also, had FPL come out and clean up some of their stuff in the area...which helped a bunch.
