Black Screen when boot with GPU

[Smhole]

I am trying to boot a 750 ti with a Gateway DX4860-UB33P but ends up giving me a black screen. The Fans and stuff still spin but only yet still have a black screen so I am wondering what can be done to potentially get this PC to boot with the GPU. When I boot it with only the iGPU (and the GPU is disconnected) it works like a charm.

 

Specs;

CPU: I5-2320

RAM: 8GB DDR3

HDD: 1TB 5400RPM

GPU: MSI Twin Frozer 750ti (can't boot so on the iGPU)

PSU: I think 300-350watt generic PSU (still has enough power to boot it)

 

My thought it would be the BIOS but I can't find anyway to update it.

Check your BIOS and see if your iGPU is selected for anything graphical-related. If that doesn't work or you can't find anything then try clearing your CMOS.
