EDIT: Use 326.41 beta drivers if you want to update, it mostly fixes the issue with compatibility. If you are using a "Korean monitor" with a single input (no scaler inside) then do not update your drivers to the new beta version (326.19) Nvidia released a couple hours ago. There is some issue in the new drivers that will no longer work with your monitor and all you see is a blank black screen upon rebooting your computer with the new drivers installed. For those of you that don't know what a Korean monitor means or if you have one or not, then you definitely don't have a monitor that would be affected by this issue.
The newest beta 326.41 seems to have fixed the issue for many people. I just finished installing on my own machine and it is working fine too.
