I'm having this problem with my PC and Gaming!! All games i play (latest games) have a stutter or lag sometimes both every little while!! i tried all types of setting even bringing down my graphics and it still stuttered!! I found out that if i disable the sound devices and then play the games everything runs smooth and no problems!!! then wen i turned it back at a lower audio hertz the problem came back!! Also about a year ago my pc had a lag with the sounds everything froze even when not playing games, what i did to fix that was to format it and got a new harddrive! (i dont know if i had messed up my onboard sounds!). is there any ideas how i can fix this without having to buy a sound card?
