And once I had the Settings page open, and changed the theme back, and it worked again. Im not sure if it will stay or if I will have to change the theme again, but just sharing information with you guys. Thanks.
I had this same problem but I found a fix after reading some interesting things in this thread.... It may have to do with a Windows theme. I just tried out a new theme. I went back to just a plain background color for the background and poof, settings is back. Try that and see if it helps all of you out. Im on Windows 8.1 Pro, 3930k @ 4.2 GHz, 32 GB Ram @ 1866, SSD's, 2 x GTX 970 in SLI. HOpe this solves it for some users.
