Well guys , i am here now after basicly trying almost anything possible. i have bought a new computer CPU : i7 5775C GPU : GTX 970 RAM : Ripjawsx 2x8gb ddr3 PSU : Antec 650W VP650P Motherboard : GA-H97-HD3 since the very first run , i am basicly having problems with any bohemia game. i've tried to run dayz standalone , arma2 & arma 3. all 3 games end up with the same result , my computer completely freezes with a buzzing sound. obviously i have checked other games as well such as Rust , Rome 2 Total War and a few others. running everything on ultra , also did some stress tests and everything is working just fine, until i run any of the 3 above. i am just out of ideas here. and im hoping you guys can think of something i haven't. i did think it could be a psu or ram issue or even a gpu , but im guessing i would get the same issue playing other games too... but no. it only happens playing arma 2 & 3 or the standalone. thanks in advance.
