Like the title say. When i watch videos or streams online my computer freezes (youtube, twitch, facebook videos etc) And i think it might be related to my new graphics card. Last week i bought a R9 290 and i got the right drivers to get it working correctly yesterday. (Had problems with low fps and such) but the freezing came when i installed the card. I have also just reinstalled windows 7 ultimate 64bit (last Saturday)
