With out seeing it, or any more information, I'd guess the CPU over heated. Check the fans and see if the cooler is still attached to the cpu/mother board.
The cpu will heat up and error out real fast if there is no cooling. If the fan is junk, or the seating of the cooler and cpu is bad you might still be ok if you redo the cooler connection and get the fan running. Be sure all the fans are running to, power supply, graphics card, case fans. Heat is the biggest enemy of computers.
Other than looking at that stuff, which is easy enough to check, it will be hard to figure out whats wrong using the message board.
