Looks like the new Crimson driver doesn't works with o.c programs like Sapphire Trixx or MSI Afterburner. This programs with new Crimson Driver, makes a problem like a black screen when you opened a computer. Can't do anything except Safe mode. And uninstalling o.c programs doesn't fix the problem. You have to uninstall AMD driver or you have to create a system restore point before install o.c programs.
I don't have any problem before Crimson driver. It begins after i installed new driver and turning off my computer.
