I have a Dell GX270 computer and have just reformatted it. Everything works find but no sound. I checked the Dell website and downloaded the correct driver for the onboard sound card and installed it but it just keeps rebooting and comes back to the screen that states that I need to install the driver (realtek 97 I think) I have even gone to their website and downloaded it but it just never seems to take. Any ideas on how to fix my sound card?
