After looking at technical documents, I could not figure out cause of memory channel A not working on intel serverboard s1200v3rps. So, I send my complete server to dealer center to initiate warranty return.
My dealer checked the system and just now sent me pictures of serverboard and CPU and they appear to be burnt.(Pictures attached). Now, my dealer has informed me that since there appears to burning, warranty might be rejected for both motherboard and CPU.
I have been using this system for past 2 and half years with heavy usage and only couple of days ago, Memory channel A not working was first sign of trouble. I regularly monitor cpu temperature during usage and cpu core temperatures did not rise above 70 C during usage. So, I want to know if it is normal for cpu and serverboard pins to get black due to heavy usage. If yes, will Intel still reject warranty claim since I have used server too heavily. If no, what are the possible reason my serverboard and CPU have got burnt so that I can take better care of my other server.
Motherboard is Intel S1200V3RPS and cpu is Intel Xeon 1245v3.

No, it is definitely abnormal.
Airflow inside a server is so critical that many manufacturers have very specific instructions as to the placement of air dams, and put dummy spacers in vacant memory slots to make sure cooling air is properly directed. Please check the Technical Product Specifications and the configuration documentation to make sure the manufacturer's airflow design is not impeded.
High content (>90%) isopropyl alcohol is often used to clean contacts after properly disconnecting power sources and taking anti-static precautions. Also use demineralized or deionized water and lint-free wipes to avoid making foreign particle issues worse.
APC has many different devices; some are just switching power supplies and not a true Uninterruptible Power Supply.
2A modern CPU cannot burn as it would have thermal throttling/thermal shutdown.
A too-sudden overload would mean PSU problem or power surge or lightning strike (do you have UPS?). Only in the first case is your computer warranty engaged. In the other cases, it is rather your home insurance that is involved.
It is only your fault if you have removed a sticker saying "Warranty void if removed", or have over-clocked the CPU or have removed and incorrectly reseated your CPU.
In any case, you are rather in the hands of your manufacturer, since he can claim circumstances that are not covered by the warranty and you have no way of proving the contrary. Good luck.
