I built a new system yesterday.... I am only using the integrated graphics. I can load the BIOS / see the Windows 7 boot-up / loading screen with VGA but not DVI.. Once it boots to Windows, DVI is fine - any ideas?
Have you tried testing the latest graphics driver version 2761?
Just need to filter your operating system version:
Also, if possible try testing Windows* 8 drivers, it appears the driver is also compatible for Windows* 7.
