From time to time I have random crashes in windows 2000. I turn off autostart and the bluescreen said, DateStamp and nv4_disp.dll is involved. The dll-file seems to handle the gfx-card but I have downloaded the latest drivers from Nvidia (unified driver). I have a Asus AGP V7100 NVIDIA GeForce MX-200 32 MB gfx-card with TV-out. The driver has version 184.108.40.206 and is digitally signed by Microsoft. nv4_disp.dll has version 220.127.116.1172. I searched the internet and many seems to share my problem.
