The hardest part of my job is when a user has done something completely dumb and I haveto explain what happened, but not make them feel like a moron. When I was coming back from lunch today I got a call from one of my users saying her computer died when she was plugging in a USB drive. I figured she had knocked loose the power or video cable and told her I'd come straight to her office after parking my car. When I got up there the monitor was on, but I noticed the computer wasn't. I hit the power button just to see if the PC came on and of course it did.
She probably knocked the power cable loose and put it back in, but once the computer turns off you have to hit that little button for it to come back on.

I know...patience...
