Around 2 weeks ago now I received my new GTX 970. I installed it into my current PC and it went reasonably smoothly. A few teething problems, with installing drivers, couple of crashes. After it was all installed I jumped on AC:Unity and managed to run it for around half an hour before it crashed. It crashed with a sharp white noise which was very brief. The screen froze and it would just stay frozen until I turned it off by the mains.
At first I thought it was an overheating problem, but monitoring my temperatures it seemed to crash around 70/80 degrees Celsius. Then I thought it was a problem with my GPU but after switching it back to my GTX 660 which I had never had a problem with previously it froze again, while idle and once again while playing CS:GO.
I'm unsure what else I can try to do I didn't change anything in my PC while installing the 970, I've tried switching the ram to different slots, I've tried uninstalling all previous drivers and i'm not sure what else I can do.
Does anybody have any ideas what could be causing my PC to crash like this? The crashes can happen from anywhere between 10 mins to 10 hours after turning my PC on. While performing intensive tasks or idle, it's all completely random.
