PC startup failure

Hi all,

My PC won't startup right now. After I push on the power-on button, all the fans and lights on the motherboard seem working right, but there're no monitor response (I have checked the monitor, it is ok), no keyboard response (the Num Lock, Caps Lock, etc. are supposed to have light on), no mouse response (the optical mouse light is not on), and no memory activities (the memory has LEDs on them which would change the lighting position should there be memory activities). My initial guess is that the motherboard is dead. Does anyone here know if there're other possible causes of this failure?

Thanx in advance!
