This is what happens when Windows 8 crashes:

The restart message proved false, and I had to reset the virtual machine.

I did the search, which told me:

The CLOCK_WATCHDOG_TIMEOUT bug check has a value of 0x00000101. This indicates that an expected clock interrupt on a secondary processor, in a multi-processor system, was not received within the allocated interval.

This proves that you make give blue screens a prettier face, but that does not make the error messages any more helpful to a non-expert user. Or should I head for my nearest computer store and ask if they have a spare clock interrupt?
