Windows 7 Monitor causes computer to shutdown

[ralphvwilliams]

I have my Dell Inspiron 530s connected to a Samsung HD TV monitor for use as a media center. When I power off my monitor, it causes the computer to shutdown/crash. When I turn the monitor back on, the computer restarts itself, occasionally going to a black screen giving startup options. The video card is a GeForce 9400 and has the latest driver from nvidia. The monitor is connected via a HDMI/DVI cable. After a few days of looking for a solution, I have no idea what might be causing this.
