Driver specific problems

I have a problem with a piece of OpenGL code i have written, currently the OpenGL code is minimal, and uses Nehe''s base code as an example, the aplication seems to work fine on all the computers i have tried it on except mine! So i currently think this is a problem with the hardware of device driver, and needs a work around. The hardware in question is a Voodoo3 3500TV, the OS is W2K, and all the app does at present is switch between fullscreen and windowed. moving on to my question, is this likely to be a hardware/driver problem, or a code problem?? And if it is hardware, is there any advice or web sites ect that anyone can recomend?? Thanks for the help Paul
