Hi Badbonji,
Thanks for the response...
I had done some troubleshooting in terms of updating and rolling back drivers for the graphics card with no success. The reason i assumed i could pinpoint the problem to the card is that i only get the stop errors when i am using the HDMI output. I can use the machine all day and using the VGA there are no issues. As soon as i plug the HD in it will fail when watching a film or surfing with any flash content.
As it is a new bulid pc i am a little reluctant to find a cure for what i consider to be a faulty part/compatability and spend alot of time, when the card is under warranty. I have returned the GT240 and have the Recommended one from Dark Mantis on order.
cheers
