i dont know where to ask this but i think this sould be the place. I have my tv a sony bravia 32 inches connected to my pc via hdmi, and i also have a directv box connected to the tv via the standard 3 cable audio and video . recently i changed from a radeon hd 5670 to a r7 260x which has its own power connector inside the computer. a 6 pin one. after that i started to saw interference watching directv on my tv, i get some strange lines going from either up an down or left to right with some audio buzzing sound, this goes away if i disconnect the hdmi from my pc. why does this happen? is my computer hardware at fault? should i worry about it ?

Small update. Even with my pc off it causes interference with the other peripherals using video input on the tv. If I plug off the pc it pretty much stops. I will ask again if this is something to worry as first time I see this happens
