Extensions are gone, help!!

Dell Dimension XPS__T
Pentium III 700
32MB Nvidia GeForce 256 4x APG

OKay, all my extensions are gone for my OpenGl, I need someones help who knows of anything I can do.

your files are screwed. I would get a new version of opengl32.dll(microsoft site) and then UNINSTALL the driver. Make sure the nvidia.dll is gone( I am not sure of the name, but it contains nv for sure) and then re-install you driver.
