I have the GA-MA785GMT-UD2H, installed Windows 7 on it and it worked fine until I booted it up. All I see is the mouse cursor on a black background when it acts like it's trying to load windows. I've sat waiting on something to happen for an hour but nothing comes up. I reset the bios to default and still no success. Also I've tried a different monitor and video card, same result.
What could be the problem?
