A minute ago I was doing nothing in particular, just on a forum, when suddenly the screen goes blank. "Odd", I think to myself, and eventually restart the PC. The monitor give some sort of power saving message that I'd never seen from it before and refuses to give signals from the PC. Reseat the power plug on the monitor and PC, still nothing. I tried switching the DVI port, and it gave me the same problem. So, I put the PC on another monitor it works good. Put the monitor on another PC, it works good. Put them both back together and they are fine again. What the heck was that? Is this going to come back to haunt me?
