Okay, everyone's sick of this but I have a slightly different problem...
I'm using the NVidia 3.78 reference drivers and my system (P2-300, 128Mb ram, TNT2 pure 32mb, running win2k 2195) works fine.
I can start quake III and run it successfully for a random length of time (1-5 minutes) before the display starts to corrupt and then the system either hangs or reboots.
Any ideas?
Incidentally, I've also tried the drivers just released by ASUS as well (v3.76b1) and I get the same result.
