I am trying to troubleshoot an older PC that was working until today. It appears to boot up correctly (I can hear the windows welcome - after one long beep and three short beeps), but the screen remains blank and the green light on the monitor blinks repeatedly. When I plug the same monitor into my laptop, it works fine. When I unplug it from the PC, it says that there is no signal. Is there some simple reason why the PC doesn't seem to recognize the monitor now?
Thanks for any solutions.
