Signal to VS4 Monitor lost

We just had a power outage. Now, when our VS4 is turned on, It beeps three times and does not send a signal to the monitor. Is our video card fried? I've tested the monitor and it works fine. It is directly plugged into the port that worked previously. The lights and the fans of the VS4 all turn on. I cannot look at the E drive on our network like I could previously. Please help.
