If we're sure your installation media is ok (used common source, works on another pc, etc), then we'll try some basic things to narrow it down.
Probably a result of an issue with your 3d card. You don't happen to have a discrete card but you've plugged your monitor into the motherboard instead of the gfx card, do you? Failing that, try updating or rolling back the drivers on your 3d card to a previous version.
May also be worth giving dgvoodoo2 a shot if the client isn't detecting your 3d card:
