OK, my wife's desktop computer monitor is posessed, or something. When she came home it was making a clicking sound, and cycling it's power 3 or 4 times a second. I tried to power it down with the power button to no effect. I've unplugged it and every time I've plugged it back in it starts cycling again. It's a flat panel Dell monitor, just over a year old. Any advice? Help? Just make the nagging stop.
