Direct3d games crashes on 9700 pro

[Imdmn04]

I am having crash/lockup problems when running direct3d games on my radeon 9700 pro.

Doom3 runs fine, but that uses opengl.
Farcry runs fine in opengl, but crashes in direct3d mode.
simcity 4 crashes
3dmark03 demo crashes

specs:
Athlon xp 2600+ @ 3200+ (the problem is not related to overclocking, it crashes too when it runs at 2600+)
albatron kx600 pro (kt600)
1gig crucial pc3200
WinXp sp2
directx9.0c
radeon9700 pro, not overclocked
catalyst 4.8

Any suggestions?

reinstall drivers and/or directx. Check your directx settings and make sure fast writes are turned off.

I've run into this exact problem with a 9500Pro, different board with the same chip.

The card would run anything OpenGL endlessly for hours straight but anything D3D based would crash within a min or 2, this includes the same game using both APIs. After trying everything imaginable the solution was to get a new yet identical card and send the old one back. I can only assume that there was a flaw somewhere in the GPU core that only asserted itself on D3D code?
