Okay so I've loved this computer to death since I got it about 2-4 weeks ago.  It's been amazing.

I had this computer running off of an hdmi cord, connected to a 50" TV.   Everything was working perfectly, no issues.  I had this computer by default use the TV as its primary.

Just recently I moved my setup to another room in the house and plugged everything back in.  Now my computer doesn't send any signals through the hdmi cord to the TV.  My TV just says "No signal".  I tried 2 other hdmi cords and I got nothing.  Today I tried plugging in an old LCD monitor I got with my Dell XPS 410 in 2007 via the DVI port.  I rebooted the computer and it still doesn't display anything.  All the monitor does is show text on the screen that says "Going into powersave mode" and just shuts off.  The computer isn't in powersave mode because I have a Alienware FX setup for that- and it makes the computer glow yellow.  Which its not doing.. its using my normal FX setup when the computer is on and operable.

I've tried having both hdmi/dvi plugged in and still nothing.  I'm basically stuck with a big powerhouse computer that I can't do anything with.

Is there a way I can reset my graphics drivers(I'm using 2 GTX 555's) to make it use my LCD screen?  It's really difficult to change any settings on your computer without being able to see.  So it would have to be some kind of internal function/shortcut on the keyboard.
