I have same problem after updating a new version of windows 1903, pc is freezing every time.
When it happened i tried installing older version of ICUE and pc freezed again.
i think that ICUE isn't optimized with new version windows 1903.
But of course people from corsair will say "everything is ok"
they are always saying "this is problem of ur PC"
but now that people started to report same problems maybe now they will understand.
it's fascinating how when i uninstalled windows and installed new windows,there wasn't any problems, but then I installed ICUE and bum my pc is freezed again.
Since i don't have it installed anymore i have no problems.
