I also have tried reinstall windows without installing nvidia driver. same problem. <br />Anyone can help me how to fix this problem. Or do i need to buy new pci audio card?<br /><br />sorry for my bad english and thx. <!--emo&:D--><img src='http://static.lowyat.net/style_emoticons/default/biggrin.gif' border='0' style='vertical-align:middle' alt='biggrin.gif' /><!--endemo--> RajibNajak Technical Support Sat, 08 Jun 2013 21:11:53 +0800
