In your bios you can set the Dr. Debug to stop auto turning off after boot up, but it only displays a AA debug code which stands for "working properly" so it is pointless to have it always running unless you just want more lighting inside your case.
Also how do you keep your cpu so cold? I use a Corsair H100i with my 3770K and it idles around 34C and gets up to 65C and sometimes 70C when I'm gaming. My room is usually around 23C. Are you using custom liquid cooling? I have IES turned on so my CPU auto downclocks itself to 1.5ghz when it idles and will boost itself to 3.8ghz when i'm gaming. I wish I could get your temps so I could actually overclock but then I will lose the IES power saving function.
