I recently resolved an issue that was causing one monitor not to be recognized by Windows by running a tool called Driver Sweeper to remove all old driver remnants, then updating to the latest nVidia drivers.

Prior to that procedure the main monitor worked fine.

After that procedure (now with the second monitor recognized), the main monitor blinks frequently. About once every 15-30 seconds, the monitor goes dark for the blink of an eye. Sometimes it only appears to happen in the bottom portion of the monitor, but other times it seems to affect the whole screen.

Can this be caused by the particular driver? Could it just be an unlucky coincidence and the main monitor is starting to fail?

I hesitate to experiment with new driver versions after having just restored the second monitor to a working state, so hope for some feedback before heading down that road.
