The lightning has been viscious this time around, my brother-in-law's parent's house was completely blown out. Every electrical item was damaged, the whole huse has to be re-wired and it will take months and cost a lot to fix.
Fantastic can I have the job of rewiring their house, I would love to takes months to rewire a house, currently an average house takes us 4 days to 2 weeks for a huge house.
The surge protector wouldn't protect against brown outs because thats not a surge its a dip, I can't imagine any way that a brown out would actually fry your machine, even if there was a massive spike after the brown out which is likely, the surge protector would have caught it.
anyway this is the universe teaching you a lesson, backup now because tomorrow is too late.
