Download and run DDU. It will stop auto hardware installation and remove any current drivers. Reboot and run the newest driver package. Run DDU once again just to click the option to set auto hardware installation back on.

I got it working, not sure what really happen that was really odd. I'll disable one GPU, and wait for the crash to happen, kind of limits me to what I can play though lol, 1440p doesn't like one GPU.
