Hey a congrats on undertaking a pc build and welcome to the builders world. To answer your question, the insulators or stand offs are mounted under the motherboard in the tray on your case, then the mounting screws go through the holes in your motherboard into the stand offs. As for the issues with it not posting to bios, I am more of a hardware guy and will leave that to the software gurus.
Thanks for the info Third Darkness I guess I had it right to begin with but it never hurts to make sure.
Hopefully I'll get this rig booted up to BIOS soon so I can play some games.
