Hi,
CLOCK_WATCHDOG_TIMEOUT error is a bsod error meaning a secondary processor crashed or locked up. This doesn't mean you have two processors but that something like your gpu chip or sound chip has crashed.
As it's been some hours since you posted has the situation changed any?
If you've managed to get back into the system and would like the dump file read then please read the thread found here and post the results:
