Hi,

Thank you for posting your query in Microsoft Community.

I understand your concern regarding the issue that you are facing.

In a PCI Express (PCIe) system, a root complex device connects the processor and memory subsystem to the PCI Express switch fabric composed of one or more switch devices.



Please reply to these questions:



1. What is the make and model of the mouse?

2. Have you tried with different USB ports?

Let us try the following methods:



PCI Express Root Complex issue:

Method 1: It is a component of the motherboard; update the chipset drivers from the manufacturer’s website and see if that helps.

PCI Express Root Complex

Hi Ricksha2,

I'm Paul, a Microsoft Community Member, and a Windows expert. I hope I can help you with your concern.

If this update already caused an issue to your PC I don't recommend that you update it. Sometimes latest driver from Windows updates can cause a problem but it mostly depends on the device. I suggest that you should wait for another PCI Express Root Complex
update in the future that doesn't have conflict or issue with your device.

I hope this helps. Feel free to ask back any questions and keep me posted.

 

PCI Express Root Complex

After I downloaded the "PCI Express Root Complex" update, my computer really got screwed up. Is it really necessary to update this?
