2 lines with amd drivers

When i installed amd drivers using autodetect after some time 2 lines start to come up on the middle of the screen (horizontally) and one part of screen freezes. I thought that maybe my GPU was broken. Then i updated drivers with device manager and the lines stop to show but radeon settings wont open.It says like i dont have drivers for my amd GPU.Is their any fix for this problem??

 

PS:I think problem started mabye after update of drivers(with radeon settings) or windows update.

I have 2 gpu-s and it is a Laptop.

- AMD Radeon R7 m265dx

-AMD Radeon (TM) R6 Graphics
