Something I remember from the first time I had to deal with a fresh install on a PC that had both an internal and a dedicated graphics card is that I needed to actually install the geforce experience drivers before it displayed anything.
Hop into your bios to see if there are any configs relating to the default video device and try hooking it up with your internal one first - the video connector coming out of your motherboard. Once you have installed the drivers from their site, you should be able to change back.
From the way you describe it though - are you sure the PC is even posting? Do you hear the windows welcome sound as the thing loads?
