Nvidia driver 1.27.2016 crashed my Arena 5 / ?

[iosubsystems]

When I was updating Nvidia driver with 361.75 (1.27.2016), after that failed attempt (no real solution yet on forums.geforce.com/default/topic/912985/geforce-drivers/official-361-75-game-ready-whql-display-driver-feedback-thread-1-27-16-/23/

...since then Arena 5.0.0 doesn't work anymore. It freezes while opening app.

I rolled back my nvidia driver to previous version... same.
Uninstalled cleaned Arena.Installed again.....same.

Any ideas?

Try using Display Driver Uninstaller to completely remove your driver then reinstall the last version that worked for you.

After I updated, everything looked crazy. The fix turned out to be going into the device manager, selecting my graphics cards and "enabling" them again. Apparently after the update they defaulted to disabled for some reason. Good luck!
