Hey everyone, i have a problem with my sound card (probably). Ok here is the story . I had windows xp he 2003 but my computer was full of some bugs and slower than ever so i decided to fromat my HDD.However my pc wouldn't boot the windows cd.So after making some "modifications" at the boot,ini file my pc wouldn't longer get into the windows. So i took a hitachi HDD from an acer aspire laptop that was broken(the laptop) and tryed to format this one.(The hitachi HDD had windows vista when on laptop) . So i now installed windows 7 ultimate and averything is just fine but one thing.I don't have sound, i tryied to download and install some drivers from realtek site but nothing happened.Pls give me any suggestions of what to do. oh and i forgot mention that i already tryied installing its own drivers.. but nothing.
