I recently installed new drivers for my new graphics card, but it was after the Blue Screen started showing up.
Firstly, which model laptop is it exactly?
Have you purchased and installed this yourself, or did you get a technician to do this for you. If it was done externally, you should really contact them before you do any fiddling with the BIOS especially. This would be in the interests of preserving your warranty of course.
Know also that by default, some BIOS(laptop or desktop) may have the setting to enable the addon slot for the gpu by default - and disables the integrated one as part of the process. This would be evidenced by the fact that there would only be one display adapter listed in the device manager when a discrete card is installed.
