If you are having problems, do not use the "latest" detonator drivers. Those are Nvidia Experimental Drivers, and as such they are often prone to problems.
Check my signature below for a link to Dangerous Dog for all the different Detonators. For that card you have in Win2k, I recommend you use the 7.58 version drivers as a starting point. Those are generally the most compatible and stable drivers for TnT-GeForce 2 level cards under Windows 2k. If that doesn't do it, try the 12.41's or the 14.10's. Make sure you are using WHQL (Windows Hardware Quality Lab) approved drivers or "Official" supported ones if possible. The "latest" drivers are often buggy and cause problems, especially on any Nvidia hardware that isn't the very latest.
Give that a try, and let me know what happens. I'm sure we can get you running.
