At my place, there was just the occasional voltage drop.
However, it was enough to repeatedly reset my new computer (blink...bootup...blink...bootup). Somehow, the other four machines in the room weren't affected, and kept on running.
A few hours later, It seems quiet outside, and I boot it up. It just gets to the desktop, then BLINK.
At least things are running OK now, and there dosen't seem to be any damage
