So, I just sold my own zotac 1060 6gb and upgraded to a 1080 off ebay. I just got it today and installed it with no issues, it powers on just fine, I get a display, and that all works. The problem is, though, that on my 144hz monitor it's locked at 64 hz, and my secondary monitor isn't even detected. I had no issues with this before, and I can't even download drivers or update them at all. Any time I try downloading video card drivers, it simply says it failed to install, along with the fact that no sound is available through my headset due to that not being detected either. My monitor is listed on the devices as a Generic Non-PnP monitor.
