A couple days ago a lightning strike knocked out half of my house's lighting. When the light's back on, I saw that my PC which was normally on 24/7 was off. The monitor, modem, printer, and speaker, all conected to the same power strip, was still on. The only thing that died was the PC. Nothing happens when I pushed the power button. One thing I noticed was that the LED indicator light on the mobo (an Abit IS-7) was still on (green light).

Suspecting that the PSU was dead, I bought a new Antec PSU (the old one was 1 380W True Power). Plugged everything to the new PSU, but still, nothing happens when I pushed the button.

Can anyone help me with this? Is there any possibility that the mobo is damaged?
