I am new to this. I have a DP45SG mobo running vista ultimate. when i download the driver from intel.com it tells me that my hardware does not support that software. I am downloading the right driver as ive checked and also the Download centre app tells me to download this driver. I built this Pc myself so could an Assembly malfunction be the problem? The audio is integrated into the board.
No this "could an Assembly malfunction be the problem" is very unlikely. Can you post the exact driver you are trying to install?
