I'm kinda at a wall here on why nothing is displaying as I'm completely new here, I maybe think I'm using the wrong cable to connect the GPU to the PSU , as the current one I'm using is 4 pin with 2 pin hanging onto as well. But the GPU is on and it a white light so I'm assuming it good?, I also didn't have the CPU power pin connected to pay, so I did that.

Maybe I need to hook the monitor into the GPU DVI but I'll need a adapter for that

Or idk, at a lost

What else could it be?
