    Default New build getting A3 Dr Debug code

    I have just tonight put the final pieces in my new build. I power on for my first POST test and it powers up but no video. On the Dr Debug LED display I get the code A3. I refer to the manual and it describes the 0xA3 code as IDE Enable. What does IDE Enable mean?

    Specs:
    CPU: i7 2600K (stock 3.4GHz)
    RAM: 2x4GB DDR3 Corsair Vengeance (8-8-8-24; 1600MHz)
    GPU: MSI N460GTX Cyclone
    HDD: Crucial 128GB SSD
    MoBo: Asrock P67 Extreme4
    PSU: Corsair TX650
    Case: CoolerMaster HAF
    OS: 64-bit Windows 7

    I am having the same problem. Happens with or without any drives (Samsung Spinpoint F3 1TB) connected.
    Did you get any more info on this or is this simply a DOA.

    Thanks

    Well Today I plugged in a ps2 keybard. Pressing F2 to get to the setup utility gets you past the A3 (IDE enable) but now gets stuck at A6 (SCSI detect). Again this happens with or without a drive attached (to either sataII or sataIII port).

    I have the exact same problem. Were you able to solve it? And how?

    I'm having this exact same problem, but with an ASROCK Extreme4 Z68 (kind of regretting going with ASROCK as this point).

    No video, boot hangs at post code A3 without any SATA connections to the MB.

    Do let us know if you've found a solution.

    I had the error and it was related to the video card. In my case it was a stupid problem, I didn't have both power connectors connected to the card.

    Try re-seating your card. If that doesn't work you could try without the card using the onboard video to see if it is your GPU.

    In my case, I had to move the monitor to a different port on the graphics card, at which point I was able to get into the BIOS set up.

    For some reason, the BIOS had defaulted the storage mode to IDE. I changed it to AHCI, but the debug code was then showing A6 (SCSI Enable I think). I then tried disabling the Marvell SATA3 controller, which cleared the A6 code. I was then able to boot cleanly and load Windows. I have no plans to utilize the Marvell SATA ports at this time, so all is well for me. If anyone is needing to use the Marvell ports, you may still be able to boot up with A6 code, as I've read elsewhere this worked for someone.

    Dear all,

    Debug code shows "A3", it maybe caused by your SATA device.

    Please kindly refer to below suggestions for testsing.
    1. Clear CMOS to try.
    2. Reinstall your SATA HDD, ODD and SATA cable to try.
    3. Plug your SATA device to other SATA ports to try.
    4. If possible, please kindly change other HDD or ODD to try.
    5. Unplug your all SATA device to check whether the symptom still occur.

    If the problem still cannot be solved, please kindly contact your local dealer to check your system.
    Thanks!

    Have a nice day
    ASRock TSD Emily

    So how does that fix the no display error that we're getting? Or are you saying that we're getting no display because we're stuck on A3?

    I had this problem when i put together my current PC a few weeks ago. PC got stuck in A3 or A9 while the screen simply doesn't switch on. I found out, that the root cause was my GTX295 (the same seems to apply to the GTX8800) which works perfectly fine on other machines. I switched to another card and the problem went away. Seems that the intel chipset has a compatability problem with some older graphic cards.
