Since there are no Win10 drivers for your motherboard at the OEM site, I looked at the components, starting with the GPU, as you had specified you wanted DirectX 12. It came out five years after that motherboard of yours did (2010).
According to AMD, creators of the Radeon GPU on that board:
ATI Radeon™ HD 4000/ATI Mobility Radeon™ HD 4000, ATI Radeon™ HD 3000/ATI Mobility Radeon™ HD 3000, and ATI Radeon™ HD 2000/ATI Mobility Radeon™ HD 2000 Series Graphics reached peak performance optimization in October, 2013.
No additional driver releases are planned for these products.
The last operating system supported using the AMD drivers was Microsoft Windows® 8 with the AMD Catalyst 13.1 driver package, which can be downloaded from the AMD Driver page : http://support.amd.com/en-us/download
Driver support for these products under Windows® 8.1 and Windows® 10 is only available via Windows Update. **Please enable Windows Update to allow it to automatically detect and install display driver version 8.970.100.9001**
Therefore, if you want DirectX 12, you will need to install an add-in-card with a GPU which supports it, and it will have its own drivers.
