Hmmmm. Check the event viewer and see if it specifies what caused the crash. If it blue screens, check the error message (ie: DRIVER_IRQ_NOT_LESS_OR_EQUAL is well, a driver issue) as well as what other processes/programs were running. Perhaps a sound driver update? If all else fails, DoubleFine should be able to help.
