matrox g400 problems under win2k

[jobberd]

There seems to be texture corruption in the games i play while running windows 2000. In half life, every once in a while, certain textures become replaced by a green static. And in Black and White, the textures for the creature, the consciences, and much of the terrain become corrupted, and are replaced by different textures. If anyone can help me out with this problem it wuld be greatly appreciated

Im running:
PIII 733mhz
192MB RAM
Matrox G400 16MB Singlehead w/driver package 5.51.005
Sound Blaster Live! Value
Asus P3V4X
DirectX 7.0
Win 2k
