So I recently bought a brand-new Gigabyte 960 with x2 6 pin ports. When it was installed, I pressed the power button on my pc and everything came to life and the fans started spinning and the leds and the graphics card fans started spinning so I knew that the graphics card had power but nothing ever appeared on the screen. Just a black screen. I know i have enough power (550w) and I even updated the bios when I took the card out. So I have the latest bios, and i even tried a different pcie slot but still didn't work. My motherboard is the msi b150 pc mate. I dont want to be stuck with integrated graphics so please help.
