I bought this board and have not had many problems with it except that it hangs up on start up every time after it completes the post but before the windows splash screen. The video does not go out, it just hangs. If you then hit the reset button, it POSTs again and then comes up with the windows was not shut down properly screen, if you hit start windows normally everything works fine. Anyone else have this problem or know a fix? I have the latest bios.
