Just got a new pc worked great the first day. Then the next morning it wouldn't display on the tv I tried on another tv and it worked so I moved the hdmi cord to the main tv again no problem. Turned it off for about an hour now it doesn't work on any tv. The tv recognizes it but when I change to that input it says no signal. I've reset both pc and tv tried 3 different hdmi cables and still not working ?
