Recently my Nvidia has been having problems with "D:\" which is a drive that doesn't even exist on my computer. I discovered that it was hidden for some reason and that i could not eject, format or do anything to it. It was simply there, causing problems for my nvidia. I tried to uninstall it through the device manager, but it did not work. If you have any idea how to fix this, please tell me. It has really been annoying me to the max over the last couple of weeks. Thanks, Oliver.
