Intel Core i5 7600K "bent pins"???

Bear with me a minute...
I'm having issues with a Device Manager malfunction of "KabyLake PCI Express Root Port #10 - A2B1".
Device Manager reports: "Device status: This device is not working properly because Windows cannot load the drivers required for this device. (Code 31) The specified request is not a valid operation for the target device."

My MSI motherboard support's (their Z270 SLI PLUS) suggestion is to: "check and make sure there is no bent pin inside the cpu socket" My build uses an Intel Core i5 7600K @ 3.80GHz. As I recall during installation, I'd need a microscope to see any "bent pins".

What on earth is MSI support expecting me to see if I disassemble my CPU and "inspect" it? I think I'd have better luck getting Congress to pass tax reform...

Update: OK. So your responses convinced me this is easier than mitigating Congress...

Well fixing a CPU's bent pins is easy but a socket now that is gonna be rather difficult.

Here's a video on fixing 'bent CPU pins':

Might give you an idea of the gravity of the damage.

I have only ever bent a few CPU socket pins when i installed an i5 4460, i did its so delicately, i was so surprised when i discovered them as i have always been so careful and have installed many CPU's in the past with no incident.

I had accidental build damage warranty so i sent it back and got a new board. After that it installed fine, this was back in 2015 thou.
well no its not necessary that you need a microscope to check any bent pins on the motherboard you can see that with your EYES too if you check the formation of the Pins carefully
i want to ask is you have this issue from the new build or the PC was working fine previosly and it just happens now?

The PC has been working beyond expectations for over two months! I am also instructed to do a CMOS reset which seems a more-likely culprit (now that I understand the difference between the CMOS and the BIOS.) I've done one-or-two BIOS updates since the build and NO ONE at MSI has suggested the CMOS reset until now. (They still haven't clarified that EACH BIOS update should be followed by a CMOS reset...at-least according to some pundits.)
A remote-assist attempt by an INTEL support person focused on the Device Manager drivers associated with "KabyLake PCI Express Root Port #10 - A2B1". The most-recent one (malfunctioning?) is dated 06/16/2015; the next-prior one 01/01/1970!!! I couldn't get any explanations 1) What function(s) this driver controls; or 2) Why an "01/01/1970" prior driver date was the last time the driver was addressed?! The INTEL tech did say he'd "escalate" the case, whatever that means...?

Thanks for the video link. I'm sure I was as careful as you describe yourself while installing my i5 7600. So after watching JayzTwoCents' abuse of an AMD CPU--I'm confident revisiting the scene of my recent INTEL install. I will repost if damage is found...

"Two points" for your answer. "Wayfall" 's reply provided more "courage" to tackle the task ahead... "Thanks!" both.
