I already figured out why it wouldn't work. It was a hardware conflict. I had to install an old Catalyst 13.something driver from Acer's website that would temporarily "disable" the iGPU to let the driver to install.Once that's finished The Catalyst driver won't open bcus the screen is hard wired to the igpu (even tho the display connection on the motherboard is closer to the Amd gpu). After that, i install Radeon Settings 17.2.1 (Bcus for some reason it gives me more settings than if i just directly installed the latest driver ) and then use the built in update utility to update the driver to the newest version. After that go into Device manager and reinstall /Reenable (or go to intel's website if clean install, bcus my laptop automatically installs and older version of the driver that i have to update manually) to re-enable the Intel GPU. Go in power settings to configure Switchable Graphics and Done. That's the pain that i need to go through when i reinstall windows, witch seems to happen way to often. I had too many hdds fail.They drop like flies ..
