Hey, I built a new computer and am currently getting the Q-Code "A2" (IDE Detect) with the yellow-green Q-LED lit (BOOT_DEVICE), with no video output to the monitor through either the HDMI or DisplayPort and no audio from the motherboard.


  • ■ 1x ASUS LGA1151 DDR4 DP HDMI M.2 USB 3.1 ATX Motherboard ROG MAXIMUS IX HERO (https://www.amazon.com/dp/B01NBHXSP6)
    ■ 1x Intel 7th Gen Intel Core Desktop Processor i7-7700K (https://www.amazon.com/dp/B01MXSI216)
    ■ 1x Corsair Vengeance LPX 32GB (2x16GB) DDR4 DRAM 2133MHz (https://www.amazon.com/dp/B0196QNBU4)
    ■1x Corsair Hydro Series H100i v2 Extreme Performance Liquid CPU Cooler (https://www.amazon.com/dp/B019EXSSB)
    ■ 1x EVGA SuperNOVA 850 G2L (https://www.amazon.com/dp/B01LXH982W)
    ■ 1x Phanteks Enthoo Evolv ATX Computer Case (https://www.amazon.com/dp/B01F0KWL6A)
    ■ 1x Samsung 850 EVO 500GB 2.5-Inch SATA III Internal SSD (https://www.amazon.com/dp/B00OBRE5UE)
I plan to use a NVIDIA GTX 1080, however it is currently in use and I wanted to get something working before bothering to remove it from the old system.

So far I have attempted the following, getting no change in result:

  • ■ Reduced number of memory cards to 1, in slot DIMM_B2.
    ■ Reconnect the hard drive to each available SATA6G_*.
    ■ Reconnect the hard drive with two different cables.
    ■ Connect a known working hard drive from an existing computer.
    ■ Connect a PNY Attache USB 2.0 Flash Drive (https://www.amazon.com/dp/B0063GKG6I), imaged as a Windows 10 Pro install device, to each available USB 2.0 port.
    ■ Remove the hard drive and connect above PNY Attache USB 2.0 Flash Drive to each available USB 2.0 port.
All fans appear to be working, with motherboard lighting on. At this point I'm at a loss.
