Whenever I am doing menial tasks on my pc, like watching YouTube, listening to music, or anything that doesn't require much power, my pc will sometimes freeze. Somedays it does it 3 times, and some days not at all. I suspect its my 970 because what happens is the screen freezes, but audio is still playing, and I can even pause the video with the spacebar like normal. After it freezes it doesn't bluescreen, but just restarts. So could my card be the issue?
