I am using windows 7 64bit. I generally use google chrome. recently i saw that even after the whole buffering the youtube videos get struck at intervals for a fraction of second. I tried with IE but the result is the same. It only hapens with youtube is guess for Now.... i ahve a monster gaming PC and has a perfectly working GPU with latest drivers. My internet speed is 2MBPS....but it is not a question of speed infact as the video gets struck even after the whole video is buffered. Also i noticed that the lag only takes place when i am watching any video in the fullscreen mode. In the normal mode of youtube the Lag does not occur. SO my question is Whats the problem....?
