This question already has an answer here:
I keep on getting a Black screen whenever I hit "Install Ubuntu" or "Try Ubuntu before Installing" I have tried the "nomodeset" and "acpi = off" and "nolapic" and none have worked. I keep a cursor...then both of my screens have the flashing cursor, then the cursor disappears and it hangs. Im running a i7 Extreme with Rampage IV with 32GB of ram. already have Windows 7 installed if that helps. Also i have tried installing from DVD and USB and get same result.
