purchased a sparkle gtx 480 for my dad's rig. installed it after uninstalling a gtx 560 ti. it recognizes it in the device manager, but nvidia drivers aren't acting like anything is there and msi ab doesn't recognize it either. i tried to uninstall the existing nvidia drivers (current whql's) and it won't let me do that either. i have tried re-downloading the whql and re-installing it, it keeps telling me the driver installation had an error. i am trying to download a driver from the sparkle website, but it is an old driver (280.26). this is what it says in the device manager: The drivers for this device are not installed. (Code 28)
To find a driver for this device, click Update Driver.
the problem is that it won't let me update the driver. it keeps getting an error and asks me to restart. when i do, nothing changed. i still have the gtx 560 ti. should i put it back in, uninstall the drivers, then put the 480 back in? i am a little lost on this one. thanks!
