Windows 10: "KabyLake PCI Express Root Port#10 - A2B1" driver not working properly

I have been looking at my device manager for a while and have noticed something unusual. The picture I posted below shows that a device named: KabyLake PCI Express Root Port #10 - A2B1 is not working properly. I have been searching abit around after solutions but I cant find one that works for me. One of the possible fixes gave me a bluescreen, which gave me no other choice than to reinstall windows. Anyways, even after the Windows reset, I got the same problem again.

Is this a common problem for Intel Kaby Lake CPU owners? I do not have any performance issues, so its not a huge problem. But it would have been nice to know why Im getting this error *Smile Maybe it worth trying to uninstall the device from the system trough the device manager?

Specs:
CPU: i5 7600K
MB: MSI Z270M
GPU: GTX 1070
RAM: Ballistix 16gb DDR4

Frustrating problem: nVidia installer cannot continue the graphics driver could not find compatible graphics hardware

Yes, I did find a solution that worked for me. I noted that I had a yellow 'bang' on the PCI express root port in Device Manager. I had thought that an unrelated issue, but apparently it was not. It seems that the PCIe express root port problem prevented
the operating system from discovering PCIe devices such as my Nvidia video card. The solution that I found, and that worked for me, was to change the driver for the PCI express root port. I looked for local drivers, selected PCI-to-PCI bridge. Let me know
if you need a step by step on that.

Good luck.

Thanks.

 

Already tried to install this driver from the own Intel website Https://downloadcenter.intel.com/product/98089/Intel-Z270-Chipset

I've verified that what you have on the site and an older version, you can try to install this from the Intel website itself.

 

Thanks! It really was outdated, but because of a reason. Something was blocking Intel from updating the drivers. Going into cmd, finding the chipset driver exe file, adding -OVERALL behind and running it fixed it.

 

Good that managed to solve your problem, if solved sue problem put as resolved and the command that used to resolve. *Biggrin
