Hey guys I just built a new pc last month and I've been having some issues.
Sometime when i play (cs go for example) the game crashes. A black screen pops up and a green frame pops up for a split second and then it creates a buzzing sound out of the speakers.
This happened with ac revelations but I saw that limiting the fps to 60 stopped it, i tried that on cs too but didnt work.
The crashes still occur after I disable the gpu overclock. CPU was stress tested for 30mins without problems. Temperatures are all very stable.Crash occurs randomly usually 20mins-ish in?
Specs-
I5 6600k 4.3ghz overclock
rx 480 1290 mhz and 2055mhz(memory) overclock
z170m mortar
hyper evo 212x
Id really appreciate any help and dont hesitate to ask for more information if i missed out anything.

The cpu has plenty of voltage infact most guides say that it will easily hit 4.4ghz without changing anything but the core clock.I cant ever get a 4.4ghz+ overclock without crashing though no matter what voltage i set.I had to give it more volts just to reach 4.3ghz stable thats another problem though.

I just checked the BIOS while booting and for some reason the CPU wasnt overclocked so it cant be from the CPU
