Motherboard Power LED

[tucrain]

When I turn on my PSU my mobo power light flashes once for a split second and then stays off. I cannot find the meaning of this anywhere. When I press the power button absolutely nothing happens, no fans or anything else. Does this sound like a dead board?

Dead board or dead power supply. Try testing it: https://www.youtube.com/watch?v=5FWXgQSokF4
