Hi everyone, I've an issue with my pc. When I'm playing videogame and sometimes even when I'm watching videos ( I think this issue happens when I see my videos on vlc or Power media player, but not on internet) the video and the audio start freezing hard. I mean the fps drop down and the audio starts to distort and to buzz. I'm pretty sure this problem appears when I move the pc. I mean i'm playing, if I move even just a little the pc, it starts giving the issue. If I don't move it there aren't problems and I've 120 fps on average. My pc has 2 video cards, an Intel hd graphics 5500 and a NVIDIA GeForce GTX 850M, and it shouldnt give issues in normal conditions. Do you know what may be the casue of this issue? Thanks in advance
