I have a 6970 Radeon hooked up to a moniter via a VGA cable. When i'm playing a GPU intensive game like Guild Wars, the card sometimes fails and i get a green or black screen which usually corrects itself. I've noticed it does this when it's too hot.
But recently i hook it up to the TV in the other room with a HDMI cable. It works great for a few minutes (video and sound coming through perfectly) but then the card will crash and i will get a blank screen on both displays and a loop of digital sound playing through just the computer speakers. This does not correct itself and i have to restart the computer and unplug the HDMI cable to stop it from doing it again.

I just wanted to know if anyone could help me with this problem

My first thought would be a bad driver or the card itself is failing. Do you have the latest driver installed What is the make/model of your power supply? Sometimes a weak PSU will not be able to keep the voltage up when the card demands. Another thing to check is air flow for the card. Be sure it is clean of dust and has plenty of air flow.
