I got lenovo y560,that got ati mobility radeon hd 5730,about 5 months before the problem starts.What happened,after installing offical driver for my grafphic card,screen just turns back,buttons are not working,but i can turn off my pc.When i roll back driver to microsoft basic display adapter everything is fine except that i can't use any applications that needs gpu.Everything is working fine in safe mode too,and i hope someone will help me,beacause i wasted soo much time on finding answer about this problem.
