I've switched graphics cards, from a Geforce 2 pro 64mb to a ATI 9600pro 128 mb. What ive read on several websites is that you can never COMPLETELY remove a graphics driver unless you can fetch certain software which nukes the old driver. Not removing completely removing the driver of a rival graphics card company can also cause instability. I've found a nuke for the Detonator Drivers, but nothing for the new Forceware driver which still has fingerprints on my computer. I can?t reformat again way to many files to move around.
