I just got this laptop and after the first few days I started to have this weird lag.  At first I thought it was just the game I was playing, but it also does it on youtube and anything involving video.  It's like a lag spike, but it freezes the screen and makes an awful audio sound.   It only lasts 3 seconds.   Did I screw something up or should I just send it back.  

It happens on CS:GO, League of Legends, Youtube videos on lowest settings.   All graphics on games have been turned up or down.  Still happens.  I have messed with the graphics and turned them down from the nvidia controls and still happens.
