i have a nvidia GT240 which i know works because i used it in a different pc. when i switch on the computer the fan on the card start working and i see the desktop ( in bad resolution though ). i thought the problem might be outdated drivers , but the card does not appear in device manager. the only thing in device manager under display adapters is : "Standart VGA Graphics Adapter " (which is the onboard graphics chip i think ). I thought that the motherboard might be broken and therefore not detect the card so i switched the card with another i had lying around and it worked no problem and got shown in the device manager. I cannot figure out what the problem could be , please help
