    These are the current ID, prior to driver install, for reference.

    So I have a problem, every time I reinstall windows, everything works fine initially (as I could show you the above screenshots). BUT, as soon as I reboot, I have no more video.
    I did stop windows update to me sure it wasn't that, but I did not find how to deactivate the RTX card so it doesn't "try" to use it until I fix it.

    When I right click on the RTX in the device manager, I don't have the "disable device" option, nor update driver or uninstall, I only have scan or properties. Seems as soon as I reboot and the RTX+UHD are enabled, everything stops working. I am trying to see how I can disable it another way to stop the conflict that seem to appear.

    Dump your VBIOS following my instructions, and let's see what's going on.

    I need to figure out a way to do it. When I install windows, I don't turn on internet and I have two "Microsoft Basic Display Adapter", I disabled both and then can install all drivers that I have placed on my USB stick

    Then when I connect to internet, even though I have windows update off and both video adapters disabled, it still downloads something and reenables both adapters and then it crashes. When it updates, the "Microsoft Basic Display Adapter" becomes Intel UHD 630 and Nvidia Quadro RTX3000... Before having a conflict and BSOD. When the two adapters become "live" I can disable the UHD but cannot disable the Quadro

    I will try to do vbios and upload first when they are both windows adapters and then when they are UHD/Quadro but I'm not sure I'll be able to upload here.

    Btw the dell Quadro driver they have on their website is 442.83 and your version 451.77 so Dell seems late in their updates

    Do not connect to the Internet. Use your second computer to download nvflash and copy it onto the USB drive, and execute it from the drive on your Precision.

    Your VBIOS version is 90.06.2D.00.D1, whereas the VBIOS from a 7540 RTX 3000 I have is 90.06.39.00.63. There is a VBIOS of the 7740 RTX 3000 (I think) here, which has version 90.06.39.00.70, which is more likely to match up. It also reinforces the possibility that you have an engineering sample with a pre-release VBIOS.

    Download the new one, and, once again, using nvflash, execute the following command:
    Code:
    .\nvflash64_patched_5.590.0.exe -6 '.\220318.rom'
    and reboot.

    This is normal. Dell does not continuously update their NVIDIA driver. You might see two or three updates per year from Dell (slowing down as the system ages) whereas NVIDIA pushes out an update on their website once every 4-6 weeks. I do recommend that you stick with Dell's driver, at least until you are 100% sure that everything is stable.
