So I recently got a Mac Pro 2009 4,1 dual cpu that came with the GT 120. When I boot up the computer, it takes about 15 seconds before I hear the Apple chime and then I see a black screen for another 15 seconds before seeing a gray screen with a loading bar before I get to finally log on. I don't see a boot screen. I reset the PRAM and SMC, upgraded to 5,1 and High Sierra and I still get this problem. I thought the GT 120 was one of the drives that gives you a boot screen. What did I do wrong?
