Flickering secondary monitor since the NVIDIA update.

Details: two monitors at different refresh rates. It goes black for a moment, comes back, sometimes teh windows jump to teh main screen 馃う Ive rebooted plenty. Id love a checklist rather than random tips, since Ive already tried random tips. I have about an hour tonight to test things, and I would rather go through them in a sensible order. Tell me what you would check first and I will report back with results. pls help 馃檹
