Recently a friend, very computer literate, helped me with a problem with my PC, but when I got it back there was no sound. He said he had forgotten to install the sound driver and emailed a link for this. Unfortunately it only gets so far and then tells me that it 'Can't find driver, reboot and try again.' I believe the driver is HP Compaq something or other but the link takes me to a page Soundmax Cadenza where I then get the error message.
