There is still no sound on my computer..

Hello,

My computer still got no sounds after i followed what i just read on the comments of the other people.. i checked on the the computer management to see in the windows audio it is selected to "Automatic" and then also if it is on "Start" status.. but it seems no sounds appearing.. i'm thinking if the SP3 of the OS of my computer is not compatible with my sound card..

i'm hoping anyone can help me.. thanks
