After i had upgraded my comp from ddr2 to ddr3 8gb and a new mobo also a 8350 cpu. I had started to get in game graphics problems before i had put anything in my computer my graphics card was doing just fine (r9 270x) until I upgraded it. After playing H1Z1 it crashes 30 minutes in. But when im playing reign of kings or arma 2 it crashes like 8 hours later. When i play arma 3 it never crashes. When it crashes my screen goes into lines and what ever color was most present it will have as a back ground. After that I will hard boot but if i try starting my comp up to quick it will just stay at the start up screen but if I wait like a minute it will start up fine
