Otherwise we can't tell if it's the source of the issue.
If the 970 is that new, and still fails, that's a warranty issue. It doesn't sound fried but may be failing.
Recently I purchased an Elgato capture card, which sits nicely in beside my graphics card. I had to switch with a DVI input, which even when screwed in, I have to sometimes unplug and plug back in. I'm getting green glitter on my display. I don't know what else to call it. It's not everywhere-- only on pictures, including the one I have set as my desktop wallpaper. I'm hoping this is an issue with either the cable or the monitor. If it's the graphics card, I'll lose my mind. It's a GTX 970 which I bought in the spring of this year, and if it got fried somehow I'll quite literally go live in the woods without ever touching another piece of technology in my natural born life.
