did you go into the BIOS and tell it to use the PCI-e GPU and not the onboard?

OK, let me make sure i understand the issue correctly, The GPU does work But only shows a black screen with a white cursor / With the GPU connected the system refuses to access the BIOS / The GPU on the CPU works fine, system will boot and operate fine?

what motherboard do you have? Do you have a different PCI-e slot you can try the GPU in just to test? Something is not passing a POST test (Power On Self Test) and this is why it is hanging.

My thinking is that either a Bad motherboard or a bad card at this point, just going by the info that has been given. Do you have an old GPU kicking around you can test to see if it will boot? or have a friend you can test your GPU in there machine to see if it works?

Motherboard is gigabyte z77n, it's good and boots fine when the gpu is not installed, windows loads and all is good.
But once I try and boot up with the 760 plugged in nothing works.

Sorry for the late response but I needed some sleep. The reason the GPU driver will not install is because the GPU needs to be in the machine and working for the driver to detect it and install. This helps prevent wrong drivers from being installed and creating major havoc.

either the GPU is bad or the Motherboards PCI-e slot is bad. test your GPU in a different machine to fine out if it will work in that PC and try a different card in your machine to make sure the PCI-e slot is good.
