I have a Powercolor Devil 13 R390X2 and an AMD FX-8350 running Windows 10. Starting with Catalyst 15.7, the computer will freeze during startup; I see the Windows logo, then the screen goes dark and never boots. The strange thing is that it only does this during a cold bootup; if you restart the machine once, it will get past the login screen. Sometimes it will lock up after login, but again, this eventually goes away with one or more hard resets.
Switching back to Catalyst 14 drivers makes the problem go away. This was not a problem under Windows 8.
I know that there are lots of problems with AMD's drivers right now. Has anyone had similar issues and found a solution?
