Hello, I want to ask about the video card, my video adapter AMD Radeon HD 6970. I have been using your products and this video adapter for a long time, and there was the following problem. Previously, the video card normally pulled the game which now does not pull,the video adapter itself began to heat up very much, a couple of minutes will sit in some game and the image disappears,as if the monitor turned off but it's okay,at the same time from the computer there is a very strong noise. I don't know much about computers myself. I hope I have explained the situation, and I hope you will help me.
