Figured it out!
Last night, I bought a sound card that wasn't detected in Device Manager (Win7x64). Updated the BIOS and was good to go. Now, I installed the USB 3.0 drivers (BIOS and USB drivers @ http://www.asus.com/Motherboards/P8Z77V_LE/#support_Download_30
) and everything is working good
Also note, you DO need to put the BIOS on a USB drive to update it. Will NOT read from a HDD/SSD.
