SOLVED: This problem seems to have solved itself unless I'm having some kind of intermittent power supply thing that has just gone for the moment.
SOLUTION (or coincidence): I switched from my HD to monitor via HDMI to my old one via DVI. Things worked fine it seemed. Then tried just switching my better monitor to a lower resolution, which also worked. Then for some reason everything was just fixed when I went back to 1080p where I started... Something needed to reset, I suppose, but I don't know what. Problem is gone though.

I was overclocking my GTX 970 and got black screen when I hit apply. Had to hard reset. After rebooting it showed up to the launching Windows screen then the display went blank. I put my old GTX 660 back in, booted, uninstalled the drivers, and put the 970 back in/reinstalled drivers. The 970 displays again, but now my entire windows is lagging. Slow mouse movement even with nothing running, and games are unplayably slow. Mouse still gets where I want it basically on time, but it's like when a game has a low frame rate.
The strange thing is it is happening now regardless of which GPU I boot up with, or whether I use the most recent drivers or older ones. Windows behaves normally and my mouse doesn't lag before I hav installed the nvidia drivers. But once I'm not using the standard vga drivers everything slows down like some virus (both cards).
Not a thing wrong before I hit apply on that overlock, but it doesn't seem like that could affect my old card.
