Win2000 3D HANGS HANGS HANGS !!!

[seba]

I have Win2000 build 2195 and latest Matrox drivers 5.03
The computer freezes at any 3d application, opengl and direct3d. Half-life, Unreal, and even 3D screen savers are locking up!
I disabled AGP turbo and frame buffer writing in the BIOS but the PC still locks.
Any ideas?
Asus P5A rev. 1.04 BIOS 1010.003
Ali Aladdin V chipset
K6-III 450, 128 MB PC-100
The system worked perfectly and very stable under Win98.
Thank you very much

I had a similar problem, but with an Athlon System. My solution, DO NOT use the 5.03 drivers. They gave me all kinds of problems. Use the 5.01 drivers. They worked perfectly for me.

OK thank you I will try later.
In the meanwhile I tried all kind of stuff.
Direct3D now works with Bus mastering disabled. All the rest is turned on (agp turbo, 256mb aperture, frame buffer, 32bit zbuffer etc). Unreal works perfectly, half-life also but when I'm playing and I press the "esc" button I get a blank screen - have to terminate the game in task manager if I want to quit it. The screen savers work also good but Unreal and Half-life in OpenGL hang.
So I will try the 5.01 drivers and enable bus mastering again. Thank you for the advice!
