Really need help as am absolutely clueless. So have normal desktop pc and flatscreen monitor but for the past 4 days when I get up in the morning, there is nothing on the screen, the pc is switched on, all buttons flashing on modem just no picture, not even the standard "no Signal" that comes up if monitor is no and pc isn't. The little green on button on the monitor flashes every so often though. I have tried reconnecting everything, rebooting etc but nothing the screen is dead until the afternoon when it suddenly decides it is working again.
I think it's the monitor will have to get another one to check (from where don't know)
