Running here 361.43 on a Win10 machine without issues so far (both LR and C1 are doing all right, with the GPU option enabled). Maybe yours is conflicting with some other driver -- those Nvidias may be finicky. (When I had this same graphics card running under Win 7, it started behaving strangely once, and the cause was Nvidia's audio driver which messed with the system's default driver. When I disabled it, the erratic video behavior ceased...).
