Strange marks on my CPU gold pads, what could those be? Should i be worried?

[zibob]

So i had to take my PC apart since i had blue screens all the time.. Couldn't figure it out. I lifted the CPU from the motherboard socket and saw a bent pin on the socket. I immidiately thought that had to be the reason for my blue screens. But i also saw some strange marks on my i7-8086K on the pads that touches the pins on the motherboard and now im really unsure if this is also a problem?

contact the seller for replacement if you bought as sealed boxed processor . While inserting cpu in socket , technician may damaged it .

I knew if one or two pins bent means , performance wont degrade , even cpu will work continuously .

I have experienced same in four years before.
