We have "panel" computer- monitor, computer is all one box on the table. We run Windows 7 and I'm in Japan far enough away from the Big One for it to have been only been a long jarring vibration- 30s to 1 minute. But now I am getting memory dumps I hope its not something I accessed- my wife could go nuts - its her computer and she's not good with computers so I'll have to persaude her to install registry software. So can an earthquake not give an immediate fault but later due to internal disruption cause the computer to malfunction. If so is there a good website preferably in Japanese that says so (she can read English). Its under warranty so she can get that internal problem fixed.
