New graphics card marked with error code 12 in device manager

Hi all,

I have recently installed a new graphics card on my Windows 10 pc (1050 Ti branded Asus) but I am not

able to use it because it appears that there is a resource conflict that I can't specify more accurately.

Before installing it, I reinstalled the OS from scratch in order to avoid a driver conflict but it appears that wasn't enough.

The driver installation from GeForce Experience fails too (I have restarted the pc twice and it keeps on

asking to install the same version of the driver, 391.24).

I tried troubleshooting from the settings in the OS but, after identifing the error in Nvidia 1050 Ti, it tells me that it is impossible to identify the problem. The last idea was updating BIOS but no one is available. So I am using the integrated graphics for now, but I hope someone can help me.

    Hi to everyone.

    Sorry for reviving this thread, but I think I've actually found a solution to this problem, so I'd like to share it with you for the interest of the entire community. I'll start off by explaining what happened in my particular case.

    This morning, I've decided to revive a very old laptop from 2010. I've opened it, replaced thermal compound, cleaned it up and installed a SSD.

    Then, I've installed Windows 10 in UEFI mode (keep this in mind!) and I've installed all the updates from Windows Update. Once done, the dedicated GPU (NVIDIA GeForce GT 540M) was showing up this Error Code 12 complaining about a resource conflict.

    I've literally searched everywhere and I stumbled across several threads (including this one) with people suggesting to change BIOS settings, reset BIOS settings, change PCIe Gen. to 1, disable as many devices as possible in order to free up resources and so on. Nothing worked at all.

    Then I soon remembered what I learned about UEFI: UEFI shares more devices to the OS due to how the standard works. So, what if just installing the OS in BIOS mode (ie. disabling UEFI boot, booting in Legacy mode and installing the OS in a MBR device) fixed the problem?

    So I proceeded disabling UEFI boot in BIOS, this can be achieved in different ways depending on your machine:

    • Set "UEFI Boot" to disabled
    • Set "CMS Mode" to enabled
    • Set "Legacy boot" to enabled

    Once I've done that, I've created a Windows Installation flash drive:

    • The drive must be MBR (not GPT!)
    • The drive must have only 1 partition, formatted with FAT32 filesystem
    • Drive's partition must be flagged as "active" so that the system can boot it
    • Just copy Windows's ISO content to the flash drive then

    Plug the drive in your system, access the boot menu using F12 and select the flash drive. Format the main drive and install Windows.

    Boom, error has been fixed. And both iGPU and dGPU work perfectly fine.

    Have you tried manually installing the nVidia driver?

    I have just did, using both the driver downloaded from the Asus site and the available ones from the OS (all three showed in the picture). The error code 12 persists.

    The most similar setting that I found is about PCI slot protection, I disabled it for the graphics card slot but it seems that it turned off, so the OS can't detect the graphics card

    Try to find your PnP/PCI Configurations in the BIOS. There should be something along the lines of "Resources Controlled By".

    Set that to Auto and see if that fixes the problem.
