I need to know how to uninstall my GPU's drivers completly and install the newest drivers. Also i need to know how to unlock the BIOS overclocking settings on this Dell Gen 2 so i can overclock the Processor. Also on my other computer i need to know the same thing and the motherboard on that one is by Asus P4B266-LM and the buss type is Intel GTL+. Where would you go to get updates for the BIOS and chipsets? What software would you people recommend to overclock CPU's and GPU's?
