Hi all,basically iv got a new gfx card,moniter and sdd drive so fresh install of windows etc.when i play a video on youtube its all jumping,if i wave my cursor over the video the frames must drop to like 1 frame every 5 seconds.it also lags all tabs if i go onto the video and watch it etc,the video will freeze but the sound continues fine.reinstalled firefox and flash player,disabled all add ons etc.updated all my drivers etc,even trying to scroll down the page can freeze it for 5+ seconds,everything fine in chrome but im a firefox guy! :P
