my computer hdmi port (that was working perfectly fine last night/ this morning) has stopped working. (The hdmi itself is connected from the graphics card to the tv as of now). I plug it in connecting it my ps3 and play that for a bit. after a while I got bored of playing the ps3, connect it the hdmi port(motherboard). I think i may have been a bit rough with it and now i'm not receiving any input signal from the tv. Please help
