We ship a PC/software bundle and I have a customer whose system failed to startup (quick bluescreen/reboot/bluscreen/reboot etc..) and the last known & recovery options didn't work.
We pulled a disk, chkdsk shows thousands of bad files, and a virus scan shows no virus. (This is Win7 Pro with dual SSD drives using Windows Dynamic Disk mirroring, and both drives are equally affected.)
The customer wants to know what happened, and I'm at a loss. Sure I can say "the OS corrupted the file-system" but that seems incomplete. There was no sudden loss of power that the customer remembers.
Can anybody suggest a way I can actually find root cause?
