I shut my computer down before a storm about a week ago. I left it off for about a day. When I went back to turn on my computer my monitor wouldn't come on. Everything else came on as usual, but my monitor appears as though there is no power getting to it. I plugged in an extra monitor that I had and it works just fine. What could be the problem. The monitor is not even as old as the computer itself. Thanks for any help. Sandy
