When I first built my pc I had an MSI GTX 1070, which started artifacting after about a year of use. I RMDAd the card, and in return, I was sent an MSI Duke GTX 1070 ti. I never took it out of the box, but I have recently been looking to sell it. Once I put it into my computer, the fans were spinning and the LEDs were on, but there was no single to any of my inputs. When I put my main card back in, it worked fine but had uninstalled Nvidia control panel. Is this a dead card, or should I try to troubleshoot more?
