Few things.
That Q code is loading microcode.
There are several other things to consider.
Ive been stumped then found the dumbest thing, switches out of position. Double check all of your dip switches are in the correct position. PCIE all to on, LN2 slow boot off etc.
download and rename latest BIOS as appropriate for you MOBO and flash to latest BIOS. If this is a Zenith extreme it shoud be renamed to ZE.cap and place that on a fat 32 formatted drive with nothing else on it. Smaller size 8GB or less is preferred.

Again if this is zenith extreme it should have the BIOS flashback feature. Simply put prepared usb drive with ZE.cap file on it in USB port labeled BIOS on the back plane. Then with power applied to machine but not started in and shape or fashion press and hold the button on the top of the backplane labeled BIOS until it starts flashing then walk away, get an espresso or beer whatever and give it a few minutes until it stops flashing signaling that it is complete. If it flashes a few times and stops then the file loaded is either not named correctly, the file is corrupt or you dont have the USB drive in the correct USB port on the back plane. Start off with only keyboard and mouse, nothing else plugged into USB ports except the one labeled BIOS with your ZE.CAP file. From there you should be able to get into the BIOS when its done by starting machine and spamming the F2. Load optimized defaults and let it post. Im assuming you havent loaded the OS yet. Get to where you can get in the BIOS and check your hardware first.

Hopefully that will solve it as Im not 100% sure what motherboard you have.

If you still cant get into BIOS remove all but one stick of ram. Double check that the ram you have is listed on the Qualfied vendors list on the ASUS website for your mother board.
The last photo you showed with the LED lights its as if its looking for an OS drive. PCIE lot amber for slot one is showing its populated. Could possibly be faulty GPU. Reseat and double check power connections.
