You on windows? to the best of my knowledge, XP anyway (maybe older), you can go to the control panel over to system, then I believe device mananger. There should be a list of what hardware you have, and the brand names (possibly some info about it). it should be near the top; the graphic card. forgot what they called it. drivers, or something drivers I think.
that should tell you if it's like an ATI or NVIDIA.
