Hello,

I was hoping to find answer but coulnd find a relatable topic so i made this.
So, I got this CPU Intel i5 7700, from a friend..who used it for a while then made an upgrade, MBO/CPU, so sent me this CPU, he says have no idea what happend so I cant say first handed what happend to it before hand, as far as I know this couldnt be overclocking issue, the pictures will speak for them selves, I tried the cpu at a friend and it wont boot.

My question is, can anyone guess what happend and can it be repaired?

on the video might be seen better, 5 pins damaged

Two photos (for some reason doesnt allow me to insert image directly, so here is the link)

I think excessive current through the pads could have caused the discoloration.
I think yes, but how was he able run and use the processor all that time? or this could've happend during dismounting? maybe with still connected PSU?
Also its not a discoloration, its that brass or gold plating layer is missing and that grey layer is showing under.

What motherboard are you using?
Does it have necessary BIOS update to support i7 7700?
I dont have a test MBO/PC, and I cant recall what MBO or bios version my friend had at the time we tried, but I remember we checked the support list for this cause and everything was green.
