Riva TNT2 graphics card troubleshooting

So, I’ve got this old relic sitting on my desk—a Pentium III running at 733 MHz with 256 MB of SD RAM, a 20 GB hard drive, and an onboard NVIDIA Riva TNT2 graphics chip. I ran a quick Everest benchmark and it’s reporting 24 MB of video memory, and I’ve gone ahead and installed the Aladdin TNT2 drivers for it. The OS is Windows XP Service Pack 3. Now, the screen flickers every now and then, which is a bit annoying, but the real headache starts when I try to actually play some games. Specifically, I'm trying to get Call of Duty 1 up and running. Even though the system specs say I meet all the requirements to launch the game, it just refuses to start. Do you think this is a driver issue with that specific card on Windows XP, or could it be something else entirely? Any help would be greatly appreciated! Cheers

So, when you say it won't launch, what exactly is happening? Are you getting an error message, or does it just fail to open entirely? I guess it would be helpful to know if you're even able to reach the main menu.
