I am wanting to know what is using root port #2 - 7A39 I can only see the root port in windows device manager and it is giving me hundreds of WHEA errors every second.
I have added some screen shots for more info and so far the only way for me to stop these errors is to disable PCI Express native power management.
I don't think there is any performance loss doing this but maybe the system uses more power I am not sure but I am curious why I am getting all of these errors and since the error is tracing back to the Intel chipset root port #2 I am hoping someone from Intel or anyone who knows more can help.

Hello, @UserMac.
Thank you for posting on the Intel® communities.
I am sorry to hear what is happening with your PC, I will gladly assist you here.
The PCI Express Root port is a part of your motherboard drivers that allows you to connect and access devices to your PC in an efficient, faster, and reliable manner.
Have you installed the chipset driver for your motherboard? This can be found on your Motherboard Manufacturer's website.
Best regards,
Jocelyn M.

Hello, @UserMac.
Thank you for the information provided.
It is hard to determine where it is connected the Intel PCI Express Root Port #2 as this is going to depend on your Motherboard design, it can be connected to a SATA controller or any other controller.
Since you have installed all your motherboard drivers, we recommend you to contact your Motherboard Manufacturer for further assistance.
Best regards,
Jocelyn M.
