idk if its driver issue or problem with the video card ... install latest driver for Windows 7 64bit , so far game work fine , video playback via HDMI port doesnt work well for I . have get like 5 bsod today already . it start play video fine , as soon as I touch the pc while do video playback , video will screw up , mouse cursor also , all text rendering go weird in my pc screen , and then bsod . try video playback without HDMI and so far seem ok , so I would think its either a bad hdmus port or driver issue . anyway ... very dissapointed of the card , video playback be a big must for I , that be why I be look for a HDMI part videocard . Edited : after hour of troubleshooting , it turn out to be the bad driver atti\/amd have -lrb- go figure ... what a shocking news ... -rrb- . reinstall Catalyst 12.3 driver , which be the one give I the video playback issue . use drive sweep , go to 12.2 , same thing . uninstalled driver and use the VGA driver from Windows and video didnt fail , so at least I have a good hint that it could be driver . go to Catalyst 12.1 driver , and be play video for 2 hour without issue -lrb- issue would present randonmly , even after 2 min playback or as much as 40min without issue -rrb- . so conclusion , ATTI still make great hardware and the worst driver you could ever imagine . I be just glad it be not a hardware issue , or at least so far nothing \* cross finger \* . but I think im feed up with AMD . after my first and last AMD laptop turn out to be a lemon -lrb- ton of issue , reinstall Windows like 5 time in less than a month -rrb- , and this with the video card ... I think im back to Intel\/Nvidia for life .
