Hi all.
I've been having big problems with Direct-x on my home built machine. Basically when I run Dx-diag the direct 3d test will not run properly. I see the cube but the faces are not mapped onto it correctly. Also when I run 3d-mark 2001, any direct 3d object doesn't draw properly. For instance the dragon in dragothic is just a jumbled mess of triangles.
This seems to be a motherboard problem as I've tried a different video card in the same machine with the same problem. I'm using the latest chipset drivers, and bios.

System details: AMD Athlon 1,333
Gigabyte GA-7dxr
256MB DDR Ram
Abit Geforce2 MX400
Direct x 8.1
