I just bought a GTX 1060 GPU and I installed it on my motherboard, MSI 970 gaming, and I don't get an HDMI signal. Then I tried putting the old card back in and now I'm not getting signal on that either. I didn't touch anything other then the power cable for the video card and I don't think I damaged anything on install, no load snaps or pops or anything. I'd be convinced it's a faulty card if it wasn't that the old ones not working either. Please help.
