Couple of diagnostic questions: 1) In your last test is that the new mother board with a new PSU ( as in known working ) 2) Are you sure when wiring up the new MB you correctly connected the speaker? If red ( positive ) and black ( negative ) were not connected to the right pins in the header you would not hear a post. 3) You do not mention your video card, how you get video, what type of connection. Is the video even turning on the display to black?
My best educated guess is that you should re-check your connections also test the new mother board outside of the case, being very careful to make sure it's not shorting out against something. Also only connect the bare minim to get the video to display the bios info. Then work from there.
