I'm having a strange problem with my GTX 570 that has persisted across a complete system reinstall and several driver upgrades. On boot, my monitors will not detect a signal from the video card. I know the computer is booting because I hear the Windows start up sound, and I'm able to power off the computer. If I power back up again, the monitors get a signal from the video card and everything is peachy. This has persisted across different cables (HDMI, DVI and VGA) and different monitors (Viewsonic and Acer). It's driving me bananas! Do I just have a wacked video card, or is there something firmware-wise I can do get it to stop doing this?
