I have a Lenovo G510, and I have found the issue and permanently fixed it.
The culprit is the new Intel Drivers.
The solution:
- Boot into safe mode with Netwrorking.
- Uninistall the AMD drivers completely using DDU or AMD Cleanup Utility.
- Download the latest Intel Display Drivers from your manufacturer's website.
- Install the Intel drivers. During Installation it will show a popup that it already has new Intel Drivers. Please skip that and forcefully install these drivers. Don't restart your system yet.
- Download the latest AMD Drivers and Install it.
- Restart your system.
- No 7th step. Enjoy :D
