I had a similar problem earlier this week. I opened up the system, check some of the connections related to the monitor (unplugged and plugged back in). Closed it up, turned it on, and it runs great. Sometimes a connection is just a bet loose. I would try Jimfixer's suggestion first, as it is less labor intensive.
