My driver has been working fine but recently my graphics driver has stopped working. It says "Graphics driver not installed or not functioning properly" How do i fix this i have already installed some drivers that were apparently appropriate for my graphics card but these did not work. My Graphics are Radeon Dual Graphics HD 8750M. I have an Acer Aspire V5 552-G laptop, with 12gb of RAM running Windows 10 Home 64 bit. It has a AMD A10-5757M 2.5 GHz APU. Which driver do I need to install and how do I install it?
