Hi Forum Users!

I recently  bought a new (*****specced) laptop fom Samsung ( Full specs: http://goo.gl/m3TGj) with a Radeon HD7340G video chip. Now I know I should not supposed to game or anything heavy on the laptop but it is even unable to play YouTube vids that are in 1080p, isn't that a little strange? I am connected to a socket when doing so... I have tried to install the latest drivers but it could be that I have failed, so any help is very much appreciated, thanks!!
