tnt 2 m64

i have nvidia tnt2 m64 agp with a amd 950 t-bird and 128 mb of ram on win 98… opengl works but only for about a min at best… then it freezes up my system… i used glsetup to configure opengl… can anyone tell me why this happens and if/how it can be solved
thanks, Damion

I have a similar setup(duron not t-bird) with a gigabyte mainboard. Make sure you have the latest drivers for the mainboard, and try set the agp speed to 2x in the bios.
