For a while now I have been getting these American Megatrend boot screens every morning when I first start up my PC (see attached).
 
It only seems to occur when I have modified 1 or more settings in the "AI Tweaker" section of the ASUS Bios, for example I have left every setting at default except Load Line Calibration, which I set to Level 4. No matter the configuration, if any of the settings in the tab are not set to default, I get this screen as a result. Also, after getting the screen, I can press F1 to go into Bios, I still have the settings and then I can Save and Close and the system successfully boots. It will also successfully boot straight to windows from power off thereafter unless I leave it off for a few hours (this is why it normally only occurs in the morning).
 
Specs:
ASUS Z170 Pro Gaming
Intel i7-6700k
HyperX Fury 2x8gb 2400MHz
 
Cheers

The changes you made have created an instability, that's what the AMI BIOS is telling you.

See, that's what I'm puzzled about.
Changing most of these settings shouldn't create system instability, for the most part.

For example I know my system can safely run 4.5ghz at 1.25v (tested PRIME95), but changing either value in the AI tweaker produces the error. This also happens with arbitrary settings that shouldn't cause instability, such as changing the base clock from "auto" to "100" (which is what auto runs at anyway).

Another thing to note is that this error only occurs from a cold boot after the PC has been completely powered off for a certain period, around a few hours. If the settings were infact creating an instability, then why can the system successfully boot still inside this period or after restarting whenever the error shows?

Thanks

This may be heat related.  A can of freeze spray might locate the culprit.  Over Clocking does more to a MOBO than just jack up some frequencies, that results in other peripheral chips to run beyond their design specs and instability is the first indication of going too far.  With normal setting does it have an faults??

i think you can tell the bios to not "halt on errors" and continue booting.

Being as it is time relayed when was the last you changed the system battery, it may be a little low and not holding settings.

Using the default settings of the AI Tweaker tab (no overclock) does not produce the error, this is what I have been doing in the meantime while I figure out the solution.

Isn't that a bit unsafe if there were to be a serious problem?

I might try to replace the battery, but the settings seem to hold after going into the Bios when the error occurs.

I have had this PC for over 1 year now, is this a reasonable time for the battery to run out?

I have computers that are 10 years old that have never had a CMOS Battery replaced.

I have tried both updating the Bios and resetting it via the jumper on the motherboard to no avail.
