Nvidia recently released its new 364.47 drivers, designed to give performance gains for those playing The Division and the new Need for Speed, but already we're seeing a lot of problems with them - it's probably best if you don't download them for now.
According to a lot of commenters on the official Nvidia forums, there have been issues with blue screen errors, problems with booting back into windows, black screen crashes, visual artefacts and more.
These new drivers are trouble. It doesn't even seem to matter which GPU or even which generation of GPU you're using, people from all parts of the GPU spectrum have run into issues.
One suggestion early on (as per VG247) was that it was being caused by having multiple monitors plugged in at once, but that hasn't been confirmed at the time of writing. The next bit of advice it's giving out is to not use the express install option, but really for now it's probably better to not install them at all.
If you are going to though, make sure you use a clean uninstall program to rip out every old Nvidia driver first, just to make sure.
