Question

Hi I have a packard bell desktop and i have a problem i need to sort out. The model of my computer is VOL-CO2.I recently wiped my computer clean and i deleted my sound driver and devices, now i have no sound on my computer.I went on the packard bell website to download the devices i need for the sound but its coming up as a fault.When i download it and try to open it the following message appears: Invalid floating point operation.Could you perhaps tell me why it does that.The driver i need is stac97n_613109010.Kind RegardsR Davids
