Closing A File Sound Like A Broken Spring

Sometimes my sound is ok , but somtimes my sound sounds really bad , even the normal "click" sound of opening a folder or closing a file sound like a broken spring , like a sound in slow motion twauonnnng and the music just very laggy and cant understand the lirics or even the music itself Now this is reflecting in the performance of my computer , its appears to in my games , suddenly the sounds of my steps or my sword swing or the shot of my gun , starts sounding as mentioned above in slow motion.
