I realised my Realtek audio program was deleted after I formatted my notebook from Windows Vista to Windows 7.
Even though, Windows 7 would actually be clever enough to install my audio drivers, but however, I was pretty sad that my Realtek audio program was gone just like that. Why was I even sad? The reason is simple, I rely a lot on the equaliser with my speaker to give it a bass boost.
Actually, after I formatted my notebook to Windows 7, I actually installed a Windows 7 audio codec which was wrong to install. But of course the end result was, my audio driver could not even startup and it even screwed up my Windows 7 themes and the theme is just purely on Windows Classic. Several services could not even startup especially my LAN.
Any Realtek audio users there? Simply just get Vista, Windows7 Driver (32/64 bits) Driver only (ZIP file). Here is the download link although, you gotta agree to the agreement: http://218.210.127.131/downloads/downloadsCheck.aspx?Langid=1&PNid=14&PFid=24&Level=4&Conn=3&DownTypeID=3&GetDown=false
