Was watching a quicktime clip of conan o'brian and then my screen went black as if there was no connection and came back on soon after. I then saw my internet connection went down (i use cable). Not too long after the connectin was back up. I checked to see if all the plugs were connected properly and they were. Not long after did screen go black and came back on again and i lost connection again but soon got it back. It happeend one more time until i decided to restart. Could it be a graphic card error? if that's the case why would it affect the internet.
