Does your bios have a setting for Aperture or Graphics aperture? If so, try
raising or lowering it to see what effects that has. It should be at least
half of what your video card memory is but you might try to set it for the
exact figure of your video card's memory. If your card is 256mb, then change
aperture to 256 and so on.

For me though, I had to set it to half of my memory to get the screen to
stop being blank. This is a longshot, but one symptom of aperture being too
low or too high is a screen blanking.
