I just received this notification.
Glad to know your build is up an running. I just completed another build with I6700K Maximus 8 Hero Alpha, Samsung 850 EVO 500GB SSD. Had similar issues with Qcode 99 and several others.
PC powered on but no video from IGPU or DGPU and no POST. MOBO hdd led stayed on wirh QCODE = IDE initialization error. PC ENTERED into a cycle of restarts and then power off. Ram QCode errors too during unsuccessful POST.
Where to begin but to start all over. I Changed monitors, G.Skill
ram not on QVL but on G.Skill
's approved MOBO list, etc.
Still no video from IGPU. So reconnected DGPU. No change.
Changed HDMI cable and reconnected to IGPU. Got video but no boot. Hmmmm. Only way to power on to attempt to get back into bios was MOBO safe boot button with CLR CMOS.
Solution: PSU VGA power connector though it clicked when connected was not making contact. Removed the Samsung USB 3.0 the Bios was detecting as a raid setup configuration with Samsung 850 EVo Ssd and as mentioned a new HDMI cable.
I reinstalled original G.Skill
Trident Z 4x4GB 3200mhz ram. CPU and Ram Overclocks so easy and system is VERY stable.
Only system hangups have been Win 10 Pro encounter errors requiring Win restarts.
I've been building PCs over 20 years and only had one bad Asus MOBO. Even a seasoned builder who was assembling late at night assumed VGA power connector made contact because it clicked. Not all HDMI cables(Amazon) are created equal and I should have known better than to connect same brand USB 3.0 drive during setup.
Enjoy your new build.
