@ Bilal: I've read that u use win Vista. I would like to inform u that vista have problems with certain agp chipsets. For example my asrock nforce 3 motherboard cannot run win vista without an a nvidia vga due to GART driver lack on the part of nvidia. That is a problem for me as i won't be able to use my new x1950 pro agp with vista. Anyway perhaps you suffer from such incompatibilities with your own system, and perhaps u should check it out.
