    Accidentally Uninstalled PCI Express Root Complex - Help!


    A few days ago, I was updating my drivers when I accidentally unstalled my PCIE root complex. Now neither my keyboard nor mouse works in Windows 10, but works in my BIOS. Is there any way of reinstalling or rolling back this driver without my keyboard or mouse? The alternative is reinstalling windows through a flash drive but I'm not keen on this.

    Cheers,


    Nick

  2. Windows 10 PCI Express Root complex Code 28

    Hello Patricia,

    Just curious how is it that you found out that the device installed on the PCI Express Root Complex is the drop / fall sensor, I'm having the same issue and have no clue how to determine what is this "unknown device" that installed on the PCI Express Root
    Complex.

    Without my mouse and keyboard, am I able to do this? I thought one has to access the installers through windows. If not, how do I install them?

    Cheers,

    Can you plug your keyboard in to another USB port to see if it is detected?
