I added this board to my system the other day and everything is working well so far. The only issue I am having is that when I shut the computer down, it doesn't actually power down all the way. The screen shuts off but the power to the motherboard never fully shuts off and the fans keep running. I tried shutting it off earlier and let it be for more than ten minutes and no luck. I currently have the F6 BIOS and I see there is a new BIOS version available. Do I need to download the new BIOS or is it something else that could be causing the problem?
