HELP For the past several months I am getting random gray pixelated screens that last for 1-3 seconds and disrupts the movie playback. It happens to MKV and MPG files. Also I have tried both RADEON HD7950 and NVIDIA GTX960 graphics cards and it still happens. It is not the source file as it is random and cannot be duplicated. Usually this happens about 3 to 5 times when watching a movie. HELP!!!!
