Vista Audio Problem

[jot17]

When I turn on my PC,the audio works fine.After few mins I get no audio at all.I tried to unplug the speakers and it still didn't work.When I restart it again it works and audio stops working after few mins after the restart.I tried updating my driver and it said it is up to date.

PC: HP A6700F
OS: Vista 64 Bit
Ram: 4GB

Go into bios and enable Realtek Ac 97 and disable the Azalia HD audio.

Thanks for the suggestion but the problems seem to fixed so far again because I restored my computer to original factory mode.
