Yesterday I formatted my computer and installed Windows XP SP3 Professional and everything was going fine until I found out that the sound wasn't working. I installed everything correctly and installed the latest sound drivers but the speakers still don't work. I have a Gatway 507GR desktop computer and the driver manufacturer is Realtek. What I have done so far: Installed sound drivers Checked if onboard audio was enabled in the BIOS Tried two sets of speakers What else can I do? The sound was working perfectly before I formatted? Please help!
