GeForce 9400 GT screen tearing

HOPEFULLY someone can help on this issue. I've searched the Net but found no real help.

In 3D games I get screen tearing. Throughout my game adjustments this tearing is less when I turn off "light Maps".
I've adjusted (very limited adjustments) the Bios and nothing seems to work.

What I have and drivers updated as far as they can go.

Windows XP-3 Pro. DirectX 9c
Gigabyte 7n400 Pro-2 MoBo.
2.5 GB DDR
GeForce 9400 GT pci (non E) graphics card.

Anyway around this screen tearing?
I'd like to keep the Light Map since it's a great game enhancement.

Well, it's been a LONG while since I asked this question.
Through this time I have totally forgotten about it.
But thanks to the Automated Birthday greeting, I'm posting my adjustments which lessened the problem.
.
Adjusted, "Image Settings" to "BALANCED".
Adjusted, "Anisotropic Filtering" to x4 was x8.

Tearing is still happening but not quite so bad.
In the game I set the "Light Map" to 'zero' and that helps a lot.

FYI for those who care to know.

Most often, "tearing" or screen separation is caused by the game rendering a "FPS" (Frames Per Second) that is so high that the monitor itself cannot refresh ("Refresh Rate") fast enough and gaps appear.

Have you tried a lower screen resolution??
