Hi. So I've got a Sapphire Radeon HD6950 2GB Flex Edition card. I've always had a problem with it running around 50°C idle, and today I wanted to run GPU-Z to see what shows up. As soon as I ran it, my monitors went into power-save mode, and I was forced to restart. This happened several months ago as well, but I gave up at that point. Any ideas what's going on?
