I had an installer over at my home installing a dishwasher. He didn't know which circuit breaker would kill the power to the DW area in the kitchen (even though they were clearly labeled) so he started repeatedly flipping the circuit breakers on and off.
Next thing I know, my computer is fried (it's the motherboard)

. Is it possible that repeatedly flipping the breakers caused a power surge and caused the damage?
Where can I get some documentation on this? I need to get some documents for insurance purposes.
Thanks so much for the help!
