When we got back from a trip we found to our dismay that one of our computers was completely dead and would not turn on at all. After some research we called Dr. Dave. Although he didn't answer, since it was on the weekend in the evening, he did call us back promptly. By the time he called we had already determined that the mother board was most likely fried from a storm and we would be replacing the whole computer. However Dr. Dave provided us with a series of helpful tips over the phone to make sure this was the case. He did this free of charge. He was very helpful, professional and prompt in his response. If we ever need computer work done in the future we will call him over the Geek Squad for sure!
