everything works great in xp or vista but then when i install windows 7 ultimate the sound is sometimes on and sometimes off. sometimes the sound icon says something like there is no sound device installed and when i boot there is sound yeah what a surprise. i googled and saw the need to install realtek sound driver of vista ultimate in vista sp1 compability mode then restarted and the sound came, i was relieved. then i start my laptop and there is again no sound. after some time i tried and there was sound and i was scared to shut down as there can be no sound again (: but then the sound problem showed up again.
what sould i do? there is no driver for windows 7 and afaik it does not really need installing.

i downloaded that vista driver and installed it but again the same problem showed up
Just use system restore,Choose a date before this started.
yeah that worked when i restored i also checked to see if any of the updates causes this problem so stopped windows update but the f#&%$#& problem showed up again and again
edit: any solution???
