My computer at work has a very frustrating and nasty habit of resetting when I plug in a USB device. Sometimes. Must have something to do with the phase of the moon or dead fish as it doesn't always do it. :) It will also (sometimes) reset if I take a meter lead from my Fluke and just touch it to the metal rim surrounding the outside of the USB connector. The other end of the meter lead can even be disconnected from the meter. Before I complain the the IT guy, has anybody ever seen anything like this before?
