I just put together a new system and can't get it to post. There is power to the mobo, there is a LED, but the power button accomplishes nothing. My first guess is that the panel connectors may be set wrong. The Antec case case manual states that the label always needs to face the front of the case, yet on the ASUS mobo that is impossible. There is four pin wide connector for the speaker and a horizontal 10 X 2 connector, not to mention the whole general layout is horizontal. I have tried various ways, label up and down but can't get a go. Black is ground, correct? Any suggestions?
