I got a brand new PC mounted with a Nvidia GTX 780 ti. It is conected to the screen with an HDMI wire, and there is also a pair of speakers conected to the screen, so I get the sound from the graphic card. The problem is that sometimes, when the graphic card is working, the speakers reproduce the little electric sounds from the inside of the card. There are not realy disturbing sounds, but I wonder, is it normal? Thanks in advance!
