Desperate for some help please!

I've just completed a brand new build using the Gigabyte Z97X Gaming G1 (motherboard.

I'm continually seeing the code A6 on the debug digital meter.
A6 Detect and install all currently connected SCSI devices.

To troubleshoot, I uninstalled the SSD I was going to use as my main Windows Boot Drive and the CD/DVD Writer. I also uninstalled the MSI R9 390 GPU card. Still I get the error code A6. What's causing this problem?

I then uninstalled the 2 sticks of Corsair Vengeance RAM, 16Gb (2x8)Gb) DDR3/1066, trying one stick only in each slot and then two sticks and swapping around again, still the error code of A6.

Is this A6 code the main cause of me not being able to boot from the SSD when everything is installed and connected?

I'm not hearing any POST beeps but maybe that's because I don't have a speaker wire in the case that goes to the relevant header. Is there a speaker on the motherboard?

All parts for this build are brand new, all purchased within the last couple of weeks.

Mother board Gigabyte Z97X Gaming G1.
Graphics GPU MSI R9 390.
Power Supply is an Enermax Platimax 1500Watt.
CPU Intel I5 4690K.
RAM Corsair Vengeance 16Gb (2x8Gb) DDR3 1066
Crucial MX200 SSD.

Viewsonic monitor using HDMI. Motherboard only has DVI, HDMI and a Display Port. I'm only using the onboard graphics using HDMI at the moment because connecting the HDMI into the back of the GPU doesn't seem to work at the moment.

According to my research, it looks like just plugging the HDMI into the GPU should allow your pc to boot.
I also found this:
"Wow... I just had an "are you serious?!" moment.

I had a sinking suspicion that the A6 code was really Ab (AB), which means the BIOS is waiting for my input. The real issue was my freaking monitor not displaying the BIOS screen properly. I'm using an old HP CRT through the VGA. I found that if you have the monitor plugged into the Mobo BEFORE powering on, the monitor displays a blank blue screen. I had to actually turn the Mobo on first, let it POST, and THEN plug the VGA cable in. The monitor then displayed the BIOS instead of just blue emptiness. So everything seems good now. Man, I was really worried too..."
Good luck.
