How disappointing and I know how you feel because it happened to me as well. Several months ago my old computer began crashing on several sites. It got worse and worse and finally died. My hubby and son work in computers and did all kinds of troubleshooting and said it was time for a new one. Off to Best Buy we went and bought me a new machine. Within 48 hours I started getting the same messages you got. Finally it wouldn't even boot. Fortunately we drove over and exchanged it with no problem. If your dad can check the wiring in the electrical boxes that certainly wouldn't hurt. I know how disappointed you are.
