Ok I just installed a fresh copy of Win 7 Home premium
So , i play a youtube video , open up a new tab and when i start browsing in the new tab
the music lags like hell and the video lags too.
I've never had this problem before the new install of w7
I've attached a video which shows what happens. TURN UP YOUR VOLUME
Here is the link for the video
