Has anyone else had trouble with the onboard ethernet adapter on any giga-byta boards? Mine worked fine for about 6 hours and then stopped working. I've tried everything I could think of from the software angle. I also know its not the hub or the cable, I tested both of those. I have re-installed everything from the drivers to the OS and even tried different OS's. Windows says there is nothing wrong with it... but it just won't work. The little light does not come on either.
