Fix for Turing and Kepler graphics cards could solve other problems too.

Nvidia has released a hotfix for its latest driver, which ostensibly fixes a 'DCP Watchdog Violation error' for last-gen graphics cards, but there's also a good chance if you're experiencing random screen flashing or the dreaded blue screen of death the new GeForce GPU software could fix that. 

The latest full Nvidia driver, version 466.63, only went live a few days ago at the start of June, but the new 466.74 hotfix can already be downloaded from Nvidia itself. Though it's worth noting that, if you do go Googling to try and find it, a search for the latest Nvidia drivers will still tell you to download the 466.63 version this hotfix is heatsolving.

A post about the hotfix on r/nvidia has a user questioning whether the new driver would have any effect on some BSODs they'd been encountering which cited nvlddmkm.sys as an issue, and an Nvidia forum rep confirmed that it should be able to address that problem too.

You can download the correct version of the hotfix driver from these links, but it's worth stating that you should really only be downloading this update if you're experiencing problems with your Nvidia-based setup. If all is golden with the 466.63 driver then you might as well stick with that rather than risk a needless update.
