| Heat can cause shutdowns as others have said, can be the fan, or ciruit boards with cracks that are expanding. Unfortunately, viruses can do the same.
The Dell techs you are reaching are probably the lower level techs. And they just go through a script like "is the computer turned on". You should demand a higher level tech (by going for a supervisor to get you to a highlevel tech). Simplistic problems can be gotten out by simple scripts, but anything tricky needs a good tech. Good luck. I would also move the data to a usb drive (relatively cheap -- possible could use your other comuputers as a temp solution). |
