Newbie here, just getting into working on my computers. I have an old eMachines T2895, 2.8 GHz celeron, 120 GB Hdd, 512 Mb DDR RAM, Realtek ALC655 onboard audio chip, running on XP home. Here is my issue. The notorious eMachine power supply fried, taking the mobo with it. The old mobo is an MSI 6714 GV. I replaced the PS with a good one from newegg. I found a used mobo from a supply house, but it was a newer revision mobo. Its a MSI 6714 GVP. After installation, everything works fine, except no audio devices recognized or listed. Reloaded drivers from manu website, but nothing. Could it be that the hardware is not added? Where is the add hardware options located? Could this be because the mobo was previously using a sound card? If so, how do i change the settings back to onboard audio? Can anyone suggest why audio devices aren't being recognized, or what my problem might be? All help would be appreciated.
