Hmm, its booting, now Linux mint 17.3 live and Unigine Heaven benchmark running.
Only problem are colors in Unigine heaven - its looks like through green glasses, but colors in system are ok, probably problem of Intel linux Skylake GPU driver.
But i would like to still like to know, that broken pin doing, there is photo which one is missing, but i didnt find any detail SC1151 pins socket description, maybe is Intels secret.

How i did it?
It was simple, i was really in hurry, i had to catch a train and i want to take MB with me.. so i removed cpu and want to install plastic socket cover, i didnt have a time to search where is manual with description how cover should be installed and i tried install it wrong way and probably by a bottom stumps of cover i touched the pins, or maybe i did after that, when i transported mB without cover in MB box - it sack and there were some cables and wifi antenna at top of mb - maybe i closed box (this itx box is pretty small and lots stuff there) with too much strength.
Problem was that i was in hurry and in this state is bigger change to make a error.
Socket replacement, i found local service which saying that is able to change it, for 60 bucks, board is 120 bucks (GIGABYTE Z170N-WIFI).. so when i would sell mb with sale (i already bough new one) i would lost "only" 120 (mb price)+ 60(repair) +20 shipping (all shipping) - (100 sale price) = 100$ its quite expensive accident.
Not related to my service but:
