Maximus VIII Hero no display (A2)

[DGBooth]

Hi all, would love some advice

 

I finally finished my build last night, but have been unable to boot so far. Spec as follows

 

Asus Maximus VIII Hero

Intel i5 7600k

16GB Vengeance LED 2666 (2x 8GB)

MSI GTX 1070 Gaming X 8GB

Kingston 120GB SSD

Seagate 2TB HDD

NZXT Kraken x61 AIO cooler

NZXT S340 Elite Case

 

Bios has been updated to support the Kanu Lake CPU (I had a different error before this)

 

On initial boot I get no display, and then boot hangs on Q Code A2 with Boot Device LED is solid orange. I have tried different SATA cables, different SATA ports and removing the 1070 and using onboard graphics from the motherboard. Still no output. 

 

The SSD, HDD and graphics card are all from my old build so I know they work. 

 

Any ideas would be greatly appreciated. Thanks in advance.

I had an issue similar to this with my rig(I can't remember if it was the sane post code but it was the same symptoms), I have the Maximus Hero VII, my problem turned out to be a USB card reader being plugged in and having a microSD to SD card adapter plugged into it without the microSD card in it, just the empty adapter. if I removed that it would boot fine, maybe try unplugging all USB devices?

Unfortunately I'm simply trying to boot without even a M+K attached. I read somewhere that at an A2 error the system has already posted but it could be an issue with drive formatting. The dives are both out of my old build and as far as I'm aware are not UEFI. I'm just not sure how to confirm that.
