My rear green onboard audio in a system with completely all new parts, is making a static pop on boot up or restart. My almost identical pc with the same speakers or headphones does not make a pop using the onboard.

I have unplugged everything but the cpu fan, tried a different power supply, tried headphones instead of my speakers, use the front panel instead of the rear, went into the bios & turned off USB3.0, firewire, even turned onboard audio back on and off still the same after it was turned back on, uninstalled the drivers & used the cd ones, the windows update ones, the gigabyte website drivers & still nothing. I even switched the screws on the standoff & took washers off. Pushed the tabs out more on the I/O shield panel & STILL.........Right after the machine posts right after as the Windows 7 Logo is forming the sound from the speakers or headphones will make a static pop noise.

Everything on the machine works perfect......in WINDOWS everything sounds fine.........its just at the same time every time, no sooner no later that it makes the sound just past the black Post bios screen once it gets at the windows 7 logo just as its done loading the image of the Windows 7 Logo.

I even called Gigabyte long distance & there tech was useless cuz he did all the stuff that i did and basically said there is interference but couldn't say what.

I am thinking the board is faulty? For being a new board that just doesn't fly with me. ANYONE HAVE ANY ANSWERS TO THIS?
