Alright, so i've googled the sh*t out of this...so apologies if someone has posted already.
Problem lies in watching video, whether it be VLC with dvd's or xvids or just youtube...i frequently get freezing. The audio will continue in the background while a still image of the video and desktop remains. In this state i'm able to move the mouse but clicking icons etc. doesn't work.
After a few seconds of this state, the screen will go a random colour, then blank/black and the audio will stop...then screen comes straight back on, audio continues from where it stopped and all icons clicked in the frozen state come into effect i.e. web browser opens etc. and gives the caution "ATI driver stopped responding and has recovered". This happens on an irregular basis but is constant at 10-15 min intervals. Games are fine.
I'm running the 10.2 catalyst, and it's been happening since I've had the card at 9.11. A million reinstalls and driver updates/rollbacks, so that's not it.

Then enter a profile name,then save and close it(Do not activate).
