HELP! My PCs got blown during a lightning

A strong lightning tripped my house circuit breaker but does this save my 2 PCs. My husband & I were working on both PCs when there when a great lightning happened. Power supply to the house got tripped and at the same time, one of the PCs gave a loud ‘pop’. I wasn’t sure which PC emitted that sound. However, one of the PCs would not turn on again. The other one could be turned on but there was no hard disk activity, therefore no booting occured. What should I do?
