Windows 10: 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?

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.

PCI Express Root Complex Troubleshooting.


After getting a couple of blue screen, and looking at it Online I ended up having a bad driver. I'm on a new built computer so I have no idea how to install the new driver for the title above I tried updating via device manager but it says it's up to date and I don't what else to do since I can't search online where I can get this driver.

Thanks on advance,
