The weird thing is that my card is still on. I tried to disable intergrated but it's not there in Windows or bios. I've been trying for five hours now and super frustrated. Ready to rip the port from the mobo.
Not sure of your exact problem but, usually you can disable the intergrated graphics through the Device Manager under Display.
I find that a good way for the PC to re-recognize the card is by removing the graphics card, disabling intergrated graphics (if enabled), shutting down, re-install the graphics card and boot the system (safe mode if you must).
