I had an asus motherboard that displayed that message in a similar situation, and it turned out that the surge had fried the a stick of memory, a graphics card, the psu, and the motherboard. Before replacing it, I would suggest carefully checking that the power supply still works before doing anything else (there's tutorials elsewhere on the internet), because every time you start up with a faulty power supply, the more stress you put on the components, and the more of them you could lose. After making sure that you have a working psu, since it is possible that any number of other components could be causing the problem, you could try removing components one by one (pci cards, hard drive, memory, ect.), try to boot into the BIOS, and leave it for a while to make sure that it continues to work. If you get down to the processor and it still doesn't work, you'll want to replace the motherboard and try again.
