It started a day ago an i don't know if it is a virus or hardware issue.A few minutes into doing anything that out puts sound such as a video or playing a game the sound starts to go slow motion. it becomes choppy and almost a static noise. When i play games it also brings down my fps. as for videos they slow down. I've also noticed that if i ignore it for a while the sound mutes itself. when i try to unmute it i hear a second of noise then it mutes itself again. i"ve speedfan and my cpu is at 50c so i know its not that. and i bought McAfee to see if it would fix the problem but nothing has changed. i even experience an issue when i type to fast. letters don't show up and spaces take their place . please help i don't know what else to do. Also i have windows 7
