Hello, I purchased a 1070 from Nvidia about 6 months ago and I started getting problems with it about 3 months ago, The gpu usage is going to 0% often and I contacted nvidia about 3 weeks ago and they told me to download old drivers to see if the problem went away but it didn't. The gpu goes from 99% in a game to 0%, the image freezes for about 4 sec. I was monitoring the temperatures and the 1070 never went above 75 C when I had the fan running at 65%, what should i do ?
