Don't feel silly. I have been involved in and heard of much sillier situations.

I will tell you one.

One day I went into work and everyone was turning on their computers and there was quite a noise going on in the general office. I went out to see what the matter was. Everyone said that their computers were not working. Sure enough there was power to the computers but blank monitors all over the place. I put in an emergency call to IT and they came running as they were getting calls from all over the place with the same problem. They rebooted every computer and ...nothing. Then someone in the office noticed that the monitors (we just got new ones) had hidden controls on the bottom of the monitors. All of the Contrast and Monitor Brightness had been set to minimum by the cleaners who wiped their cleaning cloths across the bottom of the monitors while cleaning thus making all of them show nothing when turned on.....duh!!

Thanks for the feedback.
