OGL + SMP + W2k =crash

Has any one eles had this problem W2K freezes when runing OGL programs, I have a dual PII 400 GX chipset and Geforce vid card
I can cure the problem by disabuling AGP or removing a CPU just cureus why this happens

I have the same exact problem. I have a Diamond V770 and a T-bird 900MHZ. I had no problem on my Celeron w/98 now I have a t-bird and win 2k. This sucks.
