Hmm, sounds like there may be a short with your reset circuit, that's just a wild stab though. I don't like the sound of not getting a beep. (no pun intended). Check your motherboard for black or dark spots, (signs of something being fried).
Well.. That'll be quite difficult, since the board is black itself. So, I think that's a no go. Either way would you think there's any possible fix for this? :S
