I had actualize my computer, after a lot of updates i've try to install the driver Crimson 16.7.3 that i had before actualisation but the installation did not work for the display driver. I tried different option, with autodetect utility, without, with my anti-virus and without, without the "pare-feu", but nothing works, the display driver don't install. But now there's an other problem, for install the Crimson i had uninstall current drivers by the control panel and now, instead of my R4 and my R7 in the device manager, i have a "unkwow device" for the R7 with no driver, and a Microsoft basic graphic card for the R4..........
What am i supposed to do? Which mistake did i make?
Re-edit : after i tried to re install catalist driver i tried again to install crimson edition and finally it works, i really don't know why...My both radeon R-series now appear in the device manager but I have also an unkwow device that i haven't before all of that...What the h*** is that....?
