I have a very annoying problem, and it started yesterday, whenever i try to install any of these builds the computer just hangs at the exact specific place it always does. It happens at the part "Completing Installation", and after the screen goes black with a line blinking (i think it installs the video card drivers), 4mins after it does this it just hangs, can't do anything. Videocard is: XFX GeForce 7800 GS(G71).
