Screen flashes to black randomly

reinstalling windows from old harddrive failure. Suddenly, my screen likes to "blink"; looks like it goes off, then comes back on. I think it's a redraw problem or driver conflict or some shit. I can right click the "NVIDIA Settings" button on the toolbar on the bottomright of the screen to get it to go to black at will

How do I fix?

That happens with my LCD monitor everytime I right click -> Nvidia CP or enter into Advanced display settings. I've come to live with it, as I'm pretty sure it's just my LCD monitor playing up. Annoying as hell, though.
