We had a storm the other night and even though my Mythbox is on a surge protector, for some reason it won't come on. When you hit the power button, the fans start running, the hard drives spin up and then everything shuts down. The power is still on to the motherboard because it won't do anything until you either shut off the power supply and leave it off for a few seconds or hold down the power button until it powers down.

I have replaced the power supply and the memory and nothing has changed. I'm at a loss from here. Anyone have any ideas?

Thanks,
