ive been having a major, and very irritating, problem ever since i upgraded my my computer: my sound dies in games. it happens mostly in CS:S and alittle bit in Halo. sumtimes i can simply restart the game and it'll turn bac on but other times i hav to restart my whole comp to get it working again. playing music in the background seems to make it last longer and sometimes it doesn't die at all. please help me because this has been the cause for many a stupid death.
