Ok so I have previously been able to run anything and never suffer an instability crash, now every single time I play GTA I crash within 20 minutes, most of the time 1-10 mins. I downclocked my CPU and Bus speed, CPU by 200MHZ and Bus down to default (100 MHz), this fixed it, however I moved it back to 4.5 (now 4.6) GHz and am crashing again. Why is this happening? It was always fine until I installed my new Strix GTX 980 (probably why somehow). I don't understand how a stable OC goes unstable by almost nothing, anyways I up'd voltage from 1.320 to 1.350 n will continue to go up until this stops or I get too high to be comfortable with. If anyone can explain why this is happening suddenly or a better way to resolve this please do.
