Hd 7870 Black Screen Problem with AMD drivers. I need help please

[Zetazee]

My pc is:

A10 7700k
Motherboard MSI A68HM-E33 V2(With te latest bios update 2018-11-02)
8gb Ram ddr3
1Tb hdd
"800w" Generic Power Supply(But this is not the problem)
XFX HD 7870 (With the latest vBios update)
Windows 7 64 bit

The graphics card works perfect with the Microsoft drivers. But when i try to install the AMD drivers the screen turns black. And i have to enter safe mode to uninstall them. I have been trying a lot of diferents drivers but no one works. What can i do? I think the GPU isn`t the problem because this problem is really common. Im desesperate, i have been trying for three days straight. I tried using Windows 10 and Windows 7, installing the drivers by the device manager but nothing works. I tried with another motherboard too and it`s the same.
