For some reason I was thinking laptop.  Probably because I had the problem
with mine.  A different suggestion: let the system come up (just wait a
while) and then request an alternate console with CTRL-ALT-F2 (or whatever
you favorite alternate console number is).  This should work around any
video mode issues for a graphic display since you get a text console.

If you get a text console then the issue is probably an incompatible video
mode when running in graphical mode.  If you don't get a text console then
your video card isn't being recognized.  I'm assuming you see normal POST
activity before the OS boots.

Cheers,
Dave
