Thanks
@CaseySJ for being so active and helpful! I can't appreciate this enough.
My system has been running smoothly except sometimes when starting it up with a projector connected, one screen is black and only works if I turn it off and on. We've talked about this in a previous post. Then also DRM content won't work with a projector connected but will work with two 4k monitors.
After a while of use, I started getting random system freezes. Last night it froze completely while cursor is still moveable and sound still playing but I couldn't do anything else. Keyboard didn't work, mouse clicks didn't do anything. Had to hard restart, then the freeze happened a second time.
Today I've had a similar freeze with the loading icon spinning, behavior was the same as previous freezez BUT it came back to its senses after 20-30 seconds.
I wonder what could be causing this.
