I'm using Lenovo Ideapad Y460 with AMD 5650M. I was using CCC 13.4 before, but when I updated it with CCC 13.9 or 13.11, it broke down(blue screen).
System info: win7 sp1 build 7601.
I've stopped the switchable cards and changed it to discrete card. That's all.
I hope there could be someone to solve this problem.
