Hi,
So I just put together my new build. Everything works well, except for the fact that my graphics card might be broken. Sometimes at startup, the screen becomes really distorted and remains that way until I restart. Also, programs like GPUz and GPUShark don't recognize my GPU and the former says it's a Radeon 6790 with -1Mhz base clock and mem. clock speed and a lot of other impossible stuff. I have a Gigabyte 7970GHz Edition with the latest (not beta) drivers from AMD. What seems to be happening?!
Please help!

Edit: Other than the aforementioned problems, everything else works perfectly. Is there a possibility it's a problem with my Mobo?
