Where do you have the monitor plugged into, the motherboard or GPU?

I was just wondering if there is something you needed to change in the BIOS to get it to display via your GPU and not the integrated graphics of your 5650? I found this in your manual if it needs changing over or not? Imgur: The magic of the Internet

The thing is that it wont even boot with the gpu on.Also it worked normally before i swapped my case and water cooler
