Hello, I recently build a gaming PC and for awhile I was using intel integrated graphics to play my games, but I just bought a gtx 560 ti classified ultra and have had some trouble installing it. First off when I install the GPU into the PCI express 2.0 slot the computer does not recognize it. Then whenever i plug in the pci e from my ocz 750w the computer doesn't start at all. I have tried installing it in the past but failed, i did get the fan up and running on the GPU though. I am also trying to disable the integrated graphics through bios on my msi z77a g43 motherboard. Any help would be greatly appreciated!
