I have never seen that, and trust me when I tell you, I have locked this
board up from every angle...and had to back out, start over.
Its the 'will shut off in 15 seconds' thing that bugs me..
Does it tell you 'OC failed, f1'?? Have you tried F1 at the end of the boot?
Many times I have seen 'OC failed, press F1'...Nothing to loose to try it.
(Just grasping at straws here, troubleshooting out loud thought.)
but you never know...And one other thing I would triple check..
are you absolutely sure there is nothing shorting out the back of the
board from the case, a screw..whatnot?
Unless it is just a freak RMA thing...it has got to be something simple.
Video might be helpful...to see what the lights are doing and the
exact way this is playing out on you... one of the @Asus guys will
be by...they always do... I'm still pretty sure, most don't sleep.
I fully respect any and all, unless the prove to disrespect themselves.
Egos get ugly quick...Of course those are usually the ones all frustrated
because that same ego wont allow them to ask for fear of 'looking' noobish..hahahaa
Which in my humble opinion is even more noobish...Best of Luck, brother.
