Windows 10: American Megatrends, anyone able to fix?

Switched on my PC this evening and loads up to the ASUS screen and then straight on to the American Megatrends screen and then turns off after 15 seconds. It's not picking up the mouse or keyboard so it's not allowing me to get into the settings before it switches to American Megatrends screen. Anyone got any ideas?

American Megatrends logo issue

I was building my pc I just reached the end and I have the American megatrends logo coming but no text it just says the logo and American megatrends but nothing else I was wondering what should I do from this point on

 

American Megatrend Mystery

Since the last updates on my Windows 10 computer, at start up the screen if filled with data and a large title American Megatrend at the top. Why is this suddenly starting to happe? I can see no need for it anyway.

 

American Megatrends appears

I turned on my PC and the American Megatrends logo appears. It dissapears and I see no error message. Sometimes the black screen goes away and windows boots around after a hour or so. Are there any fixes to this? Also, I see a underscore flash for my cursor, it goes invisible. My keyboard does nothing. I don’t hear any beeps. I have two monitors and my primary one goes blank. My secondary monitor has the issue. It occurs right after I turn on the PC and monitor.
