Usually, when a developer or a company releases a patch, it's supposed to fix some (if not all) the issues present in a previous version. NVIDIA's latest drivers did the exact opposite, with potentially harmful consequences as a result that may end up melting your graphics card.
The hardware giant released a driver update last week was meant to improve performance for games like the newly released Tom Clancy's The Division and Hitman games, but instead of optimizing the performance it froze people's games, with some people actually finding that their expensive graphics cards had melted. NVIDIA was quick to release a statement saying that they were investigating the issue with driver 364.47 and 364.51. That was 6 days ago, and an update fixing those issues still hasn't been released.
This would not be too much of a problem were it not for the fact that NVIDIA still hasn't deleted the potentially harmful update from their update servers, which could lead customers to download the driver update without knowing what it could cause. The problems that arise from installing this update seem to be generation agnostic, meaning that any of their cards can potentially be affected by this and apparently the people who are running multiple-monitor setups seem to be the most affected by this. The problems also don't happen instantaneously, so if you have installed the update I would strongly urge you to use something like Display Driver Uninstaller to revert the firmware back to the last stable version, which is 362.00 and can still be downloaded from the official NVIDIA website.
So, to reiterate, if you've been getting random game freezes, blue screens, and artifacting that you haven't encountered before you should downgrade as soon as possible, lest you'll be left with an expensive and toasty paperweight. You can grab the safe driver here.
