guys i am clueless about this issue im having with my pc,on certain games such as PAYDAY 2 or the newly released Shadow Warrior,i can play for 5/10 minutes then it will freeze,crash into a black screen and then continue running,however if i alt-tab to desktop,windows will report AMD Display Driver has crashed and recovered.i have tested using two psus and both of them had the same result,tried a clean install,nothing,however a friend of mine had the same problem and it turned out to be his RAM being uncompatible with his MOBO,so i checked my MOBO's compatibility list (AsRock Z77 Extreme 4) and interestingly the ram sticks im using are not on the MOBO's compatibility list (Corsair Vengeance LP 1600 mhz ddr 3 CML8GX3M2A1600C9) could the ram be causing the Driver instability? btw how can i stress test the gpu,cpu and ram because one of these 3 ``criminals`` is the culprit behind this case.
