Alan Perez was my Computer Doctor and I must say he lived up to the reputation of Computer Doctor BG on Yelp. He checked out my eMachines PC and found it to be working fine. He told me sometimes the power cord can be the problem. Then I had them change the tempered glass cover on my iPhone 7 and he found a failing drive on my 2009 Mac Mini Server. I had him change out the failing drive and I was very happy with the quality and responsiveness of getting me back up and running.
