I've googled a lot and searched the forum about this issue and I still haven't found a solution.
I have the Dell Inspiron 5567 laptop (which is supposedly running only win10 or ubuntu 16.04). I have it now running with win7 x64 and found every driver for it except for the gpu which is AMD Radeon R7 M445 and is shown as M440 in Device Manager. Now I've tried to install Crimson and download it from there but it doesn't do anything. Device Manager shows the gpu as m440 and disablesd with code 28 along with the integrated intel graphics.
I've done the steps here https://community.amd.com/thread/207699 but didn't change anything. Tried clean installing and still nothing. I've updated windows 7 to the maximum allowed before I get the "stopped supporting this OS" message from microsoft.
Crimson every time pops a window that there is no AMD driver on system after I supposedly installed it and crashes after a while with an openGL error.
