HD 7770 Won't Recognize DVI Monitor

Hi there. I have two monitors. An Acer that's just vga and a Gateway that has both vga and dvi. When I try to plug the Gateway into my ASUS HD7770-DC-1GD5-V2 via dvi, Windows doesn't recognize it. Which is weird because when I start my computer, the whole boot process is visible on the monitor up until the point when Windows loads. I have messed around with uninstalling and reinstalling the drivers and even trying older versions of the drivers, but nothing worked. I actually think that the problem might be with the drivers themselves. When the drivers aren't installed, the Gateway is recognized as a generic monitor but doesn't allow for extending the desktop. Once I install the drivers, the monitor is no longer recognized. Does anyone know how to fix this problem? Any help would be greatly appreciated.

I'm also having problems with a AMD HD 7770 and a dual monitor setup. Since I upgraded my drivers to the latest 13.1 version I have problems with de 2nd monitor. Sometimes is not recognized, sometimes remains all black, had driver crashes,...
I have Windows 8 Pro 64bit. I tried to reinstall the drivers but problems remain. I think it's 13.1 driver issue. With previous drivers I never had any problem...

card can only output to 1 analog device. DVI can actually be either depending on design and I suspect yours is anaolg.
To test this, boot up with only the dvi attached.

I tried booting it twice. Once with the monitor plugged into the dvi-i and once plugged in the dvi-d. When I plugged it into the dvi-i the monitor had no signal at all. When plugged into the dvi-d, the monitor showed the bios loading screen and then the "Starting Windows" screen. But as soon as windows start-up is done, the monitor loses signal and goes black.
