That model of acer shipped with a ATI Radeon™ X1200 originally.. It was probably removed to install the Nvidia.. Most likely, the radeon display drivers weren't removed.. So that may be why it keeps thinking its found new hardware..
Also, the bios needs to be updated , and that needed to happen before the graphics card was installed. Then.. After the graphic card is installed and the correct drive fully installed.
at this point, it would probably be best to remove the card.. reinstall the card ( physically )
Then, reinstall the correct and newest nvidia display driver from here. http://www.nvidia.com/Download/index.aspx?lang=en-us
Then, install the bios update from here. http://www.acer.com/ac/en/US/content/support-product/474;-;Veriton%20M410
Also, even if you fix the found new hardware issue for the graphics card, if that's the culprit.. You'll still need to download and install the drivers for the other "broken" or " found"new hardware from the acer site.. Or disable those broken devices altogether..
