PCI Memory & SM Bus Controllers (Yellow Triangle): Not Finding drivers to update

[Nuke615]

I recently did a complete partition wipe and clean-install of the Windows 10 operating system on a Dell XPS 8910.  The restore worked well, but when I checked Device Manager, I found that the PCI Memory & SM Bus Controllers did not have the driver updates they need (see screenshots).  I tried the device manager update utilities, but they could not find any drivers. I then utilized both Dell and Intel's support assist.  There were 6 updates for Dell, and 2 for Intel.  All these updates were installed and completed successfully, and I rebooted.  However, the triangles are still there, and I cannot locate the correct drivers to install manually,  or figure out how to correct this.  I know these are crucial components, and I would like to get these drivers updated.  Can anyone please direct me to links to the correct drivers for the devices shown, or advise me with details as to how I should proceed to correct this issue?

Thank you so much for your expert guidance and assistance in this matter.  I have attached several screenshots to help diagnose the issue and all the details for the devices.  I really appreciate the assist.

Not sure what forum I should have posted this in, so I chose "Rapid Storage Technology."  Could any moderator or site administrator please place this question into the correct category if that location is an incorrect choice by me?  I have never used this site before, and am so thankful it is here.  I anxiously await a reply to my query.  Thanks again!

Repeating from your other conversation...

Questions:

• Have you installed the Chipset Device Software package? Download link: https://dl.dell.com/FOLDER05969831M/1/Intel-Chipset-Device-Software_5MPRF_WIN_10.1.18121.8164_A09.EXE.
• Have you installed the Serial IO Driver package? Download link: https://dl.dell.com/FOLDER06626437M/4/Intel-Serial-IO-Driver_WVVGP_WIN_30.100.1943.2_A08_03.EXE.
• Have you installed the Intel Management Engine (ME) package? Download link: https://dl.dell.com/FOLDER06465777M/2/Intel-Management-Engine-Interface-Driver_5CCYM_WIN_1952.14.0.1470_A07_01.EXE.

Curiously, only the ME package is considered critical. All three of these should be considered critical. They will resolve the entries you have outstanding.

Hope this helps,

Thank you so much Mr. Pearson...you are a life saver.  I assume there is no particular order to install these?  I will begin in the order you have them listed.  and let you folks know how this turned out.
