I have just upgraded my GPU from an nVidia MSI GTX 760 to an Radeon Sapphire R9 Fury. Everything seems to work fine but the Asus screen seems to take forever to boot to Windows 10 (~3-5 mins.). During this time, my keyboard and mouse does not respond. Beforehand this process use to be instant. I made sure I uninstalled the driver and everything else nVidia. I even removed MSI Afterburner. Along with updating the mobo's bios to the latest version. Then proceed to clear the cache with Ccleaner. The problem still persist though. Not to mention tgat my priority boot is Windows Boot Manager (UEFI). Any idea on why this is happening?
