I have been searching for the right driver for my speakers. There is an exclamation point on my Multimedia Audio Driver-looking in the properties it says looking for alcx wdm.sys file-Realtek AC97, when looking through the drivers listed they all have a number eg. alc880. Can anyone tell me which driver is proper. I have downloaded two files from driver files from Realtek and they shut my system down to a black screen, had to go to restore in saftey mode. Thanx in advance.
