DP55WB sound cut off in 10 minutes approximately



before start, i would like to apologize for bad english.


I bought Intel(R) DP55WB recently ( 17/12/2009 ) and this issue occurs in Win Vista 32 bits and XP 64 bits too.


The problem: Playing Left 4 Dead, Warcraft or using Skype, listening musics in 10 minutes approx. the sound simply cut off. And only restarting PC resolves


Failed attempts: I tryed Driver Max, swap OS ( Vista 32 to XP 64 ), reinstall drivers using the CD that comming with MoBo -- and download in the net --, use automatic support intel, check BIOS but nothing resolves
