Your A8-3510MX with HD6620G is not supported by AMD with any new or updated drivers.
In fact, AMD has no Windows 10 drivers for your APU. Only Windows 8/8.1 and earlier Windows OS.
You can see if your Laptop Manufacturer's Support site has newer drivers for your APU or try AMD's Windows 8/8.1 or 7 drivers and see if they work in Windows 10: https://www.amd.com/en/support/apu/amd-series-processors/amd-a8-series-apu-for-laptops/a8-3510mx-rad...
You have a choice of two to install:
WHQL - 2015
BETA - 2016
But I highly suggest you install your Laptop Manufacturer's AMD APU driver which is 100% compatible with your laptop even if they are from 2015.
By the way, you just need to install the APU Graphics driver and it will automatically install the Integrated and Discrete GPU drivers.
