Hi to all. I am a Sony Vaio owner, with ATI HD4570 since December. Some times (5-6 times until now) the pc crashes (total screen flickering and terrible sound loop), even when i'm playing games or listenig to music or watching a video with media player. The only way to restore my pc is by pressing the power button - heavy shut down.
After searching i found in windows log file an error called atikmdag. I reinstalled windows 7, I disabled the catalyst A.I. and now the atikmdag error appeared in windows log file occasionaly the times that I open or restarting pc. (until now I haven't any crashes)
another Point is that I cannot update my catalyst because Sony does not recognize Ati driver Updates.
So all the above are usual or I should send the pc back to sony?
Sorry for my English, any suggestion will be extremely helpfull.
