Kernel 41 (63), only when gaming.

Hello guys, first of all sorry for my english I'am not a native english speaker.

I started to experience this error(Kernel 41 (63)) back in August when my Computer would only reboot when playing STEAM GAMES, like Rainbow Six or Killing Floor 2, however I could play Battlefield 4 for hours without a single crash. I thought it was an Audio Driver issue, so I did a clean windows install but the problem got bigger, it started to happen in Battlefield (1 & 4 ) too, but only at the battle report screen(end game screen) and never during a match. Since them I cant play anymore, it happens every after every match. And happens everytime while playing any Steam game.

Its important to mention that my PC has turned on itself twice this week( at 4:24 PM and 11:06 AM).

PC Specs :

CPU :i7 4790k @ 4.0ghz
MoBo :Z97 Fatal1ty Edition ASROCK
RAM : 2x4GB Vengeance @ 1600mhz
GPU : GTX 770 G1 Gaming
PSU : Corsair CX 750M



Can someone help me, I am getting crazy with this error.
