Yes, the drivers provided by GeForce Experience are installed. The 1080 isn't new. It was working wth my previouse CPU, MoBo, RAM combo. No I haven't tried reinstalling windows on this PC, though it did work in my wife' PC with no problems.

This didn't used to be a problem with my old motherboard and it isn't a problem when I stick the 1080 into my wife's PC. However, when I take my wife's 760 and put it in my PC it boots normally. The MoBo and CPU in my PC are both upgrades. They are the "wild cards" in this PC that has been functioning normally for two years now. I originally had an Intel i5 4670k running on an ASrock z97Extreme6 MoBo. Could this be a power issue? Given the wattage of my PSU I didn't think that could ever be a problem. The GPU was functioning normally before the upgrade. I did have to RMA the Mobo originally because I couldn't get it to post with either the Ryzen 2600 or my wife's Ryzen 1300x. They determined it needed the bios upgrade, but it should have posted for me with the 1300x if that was all that was wrong. However, it's possible I might have forgotten to even plug the monitor into the GPU when I was testing the 1300x with as scatterbrained as I can be sometimes. When the board returned from Asus it booted normally with my 2600, at first. Then I started having problems whenever I would restart my PC where the monitor would just lose signal after the bios splash screen. Sometimes it would even do this within bios. None of these problems exist at all when I try booting with the GTX 760. I got really frustrated with troubleshooting because I can't pin down the problem to my GPU or the MoBo and for the first time in many many years, I considered just hauling it into a PC repair shop so somebody else can troubleshoot it. I really can't afford that option right now however and would like to fix this quickly. Does anyone have any advice? Let me know if I haven't been clear on something. I'm sorry if I was too verbose.
