I've an ASUS K55DR with AMD A8-4500M APU with Radeon 7640G. The problem is the driver. There is no driver that allow the computer to boot properly because the pc stuck on black screen on boot. The problem exWith the driver version 15.7.1 WHQL and Crimson Edition 16.2.1 Beta. I've tried to disable ULPS but the pc become very hot and fans runs very fast, but the problem disappear.
What i can do for solve the problem? Thank you for the replies.
