Black screen after driver installation Windows 10 and HD7850
I have an issue installing a AMD driver for my setup:
Intel Core i5 2500K Boxed (stock speed)
Asrock Z77 Extreme4
Samsung EVO 840 250GB
Sapphire HD7850 2GB GDDR5
After a new and fresh windows 10 installation (from scratch) i try to install the drivers for the 7850. After a few minutes the screen goes black. Even a reboot results in a black screen.
I have to boot into safe mode, uninstall the drivers with DDU and then it works again but WITHOUT the driver.
From other forums i understood the Intel IGPU driver clashes with the AMD driver so i disabled the IGPU in the bios. I even tried to prevent windows 10 to install drivers for the IGPU (which it still tries even with the IGPU disabled). Still with the same result: After installation of the 7850 driver the system goes black.
I am pretty sure the 7850 is fine as i tested it under various other operating systems and with occt. with no issues at all.
