I've said this before and the above paragraph shows this is true: you should NEVER accept a client's diagnosis of a problem, nor prescription as to what to do to fix it. They might not even get the symptoms right!
The rest of this is the typical answer when SO says "I thought you said it would take you about an hour on that service call."
The proper form of troubleshooting, no matter WHAT the client says is to turn on the system and observe what the issue is, as I did. From there, move on to normal troubleshooting steps.
