Hi and thanks in advance to anyone willing to help me. I have dual nvidia gpu's configured 2 x 16 sli. I'm checking to see if my slots are bad or if its my card(s). I'm going to reset the cmos to clear the DMI pool and clear the info the bios sends to windows pertaining to the hardware connected to my asus m4n82 deluxe mobo. I know for sure that I will have to un-slot both cards and uninstall the related gpu drivers. Can anyone tell me if I should uninstall the nvidia chipset driver as well. Again any help would be greatly appreciated.
