So I have tirelessly tried everything on the internet to try and make this work, however, upon trying to install the latest drivers on my PC for the GPU it says that there is no compatible GPU. Therefore, I went into device manager and under display adaptor it is just non existent. The fan is running and the light is on but also whenever i plug my HDMI cord into it the screen just says no signal so I have plugged the HDMI cable into the motherboard instead. I really don't know what to do, please help me :(.
PS) My motherboard is an AsRock Z68 extreme 3 gem 3 btw.
