Question Melted Pin

Hello
So I own a MSI Z390 ACE for less than 2 months and had a lot of stutter in games so I decided after trying everything inside windows 10, I decided to make a hardware check and I found out that the back side of my motherboard where the CPU goes is like this. It looks completely melted I do not know if the motherboard was like this when purchased or it happened later. What are these "pins" (I hope I call them right as pins) used for ? How do they affect performance and I guess motherboard should be replaced?
These are the images of the backside of the mobo.

Those are not pins but resistors. They are there to help control the flow of voltage and current.

I would say you need to start a RMA with MSI on that. I have never seen that happen personally. The closest I have ever seen is when someone spilled liquid and the PCB starts to burn but never that area. Looks like a possible defective part to me.

I see. Could that affe

I see, thank you very much for you reply and help. Could also that explain why the games stutter with a high end PC?
 
I could see it maybe affecting stability, but I don't know about stuttering. Full system specs? Max CPU/GPU temps under load/when stuttering occurs? What resolution/refresh rate is your monitor, and do you have any gsync/freesync/vsync/etc enabled?

Edit: clean install of windows for this build?

CPU: I7 78000k
GPU: Palit rtx 2080 gaming OC
RAM: 16gb Ram G.Skilll
MOBO: Msi Z390 Ace
CPU cooler: Cryorig H7
PSU: HX 850i
Monitor: Benq Zowie XL2411P ,144HZ,1920x1080
These are the specs, these are all disabled. The temps are max 80oCYes I did a clean win 10 pro instaltion twice. Even fixed the unclean cache RAM issue.

It may not be causing the stuttering but it is still possible it could be if the voltage to the CPU is not stable enough to keep clocks stable on all cores. And be it the issue or not damage like that is never a good thing to keep running. It could cause an eventual short and/or fire on the board which would result in more damage to other components. A RMA through MSI would be the best start and then if you still have stuttering issues we can continue to troubleshot them with a known good motherboard.

Alright I will contact MSI or the store I bought the mobo and check again how the stutter will go. Thank you very much for your help much appreciated :)

UPDATE: I unscrewed the motherboard and apparently that wasnt the only ressistor that was at that state. There are almost 15 more resistors melted like that.... What could cause this? I will send the motherboard on Monday at the store I bought it since MSI Greece is not taking this kind of responsibility nor has a service for this kind of matters.
