In cases where hybrid graphics are used -- that is, the Intel HD Graphics and the (in your case) AMD HD Graphics engines are both utilized -- it is common for modifications to be made to the graphics drivers to support (amongst other things) switching between which engine is active. If this is the case, installing the generic drivers from the Intel or (in this case) AMD sites will break this support and cause no end of problems. If this is the situation - and the vendor does not provide modified versions of the drivers for Windows 10 - you may be stuck between a rock and a hard place. What you need to do is contact HP, your laptop vendor, and ask them if they modified the drivers. If they did -- and they won't provide drivers for Windows 10 -- then you should return to using Windows 8.1 (aside: I have heard that you can sometimes get away with using Windows 8.1 drivers on Windows 10; I am not your source for information regarding how to accomplish this, however). If, on the other hand, they did not modify the drivers, then you can freely download the latest drivers from the Intel and AMD download sites and use them.
Hope this explanation helps,
