R5 Graphics + R7 M440 = R8 M445DX driver issue

I have bought HP 15-AW012NT AMD A10 9600P 16GB 1TB + 8GB SSD R7 M440 Freedos 15.6" FHD Product ID: 1VG35EA but I have a problem. R7 M440 hasnt worked although I downloaded Hp drivers where its website. When I update the drivers, it changes R8 M445DX. Moreover, I downloaded APU driver too but the problem isnt solved. R7 M440 is appearing but it doesnt work. I switch high performance but the problem is still continuing. I think only R5 works because Call of Duty 4 and League of Legends  are worked on low fps. How can we fix this problem?
