weird

I recently added a second LCD monitor to my home-computer. It was working fine for the first couple of days, but then it started having problems. Every 10-20 minutes it would get really bright, and then instantly go black. The power was still connected, so it wasn't turned off. If I turned the power off for a few minutes, I could turn it back on and get another 10-20 minutes of work done before it would happen again. What could cause this behavior?
