I have connected my pc to lg tv and have been using it for a long time .But few days while watching youtube black screen appears and it shows no signal found even if I move the mouse nothing happen no keyboard keys work video is still playing and you hear the audio in the background and then I have to restart the pc again . I have set the sleep mode to never even in advanced setting i have set it to never and off .And even the screen saver is set to none. My graphic card nvidia geforce 8400gs is updated to latest driver all the other drivers are updated even the flash and chrome are upto date. Does anybody have solution for this black screen problem.
