My brother has a problem. A few days ago there was a lightning strike near his house. All the power went off but came on when he turned it on at the box. What did not come on were his computer, modem and printer. He found that if he disconnected the printer from the computer it would power up but as soon as he connected it to the computer it went off. I assume that this would also apply to the modem. Has this anything to do with his computer hard drive?
