Hey lately when ive been playing comp games the sound has turned off after about 10 mintues of play. In order to get the sound back i must restart the game. The sound otherwise is still on when i play songs. Recently ive been playing "Mafia" and my audio is built into the motherboars. is it just the game or should a better pci sound card? or should i update drivers or anything like that?

please help i hate games with no sound!!!
