What are you temperatures looking like?
Are there any sharp bends in the tubing?
Have you tried adjusting the fan speed control?
Can you see any air bubbles in the coolant?
Is the three pin connector firmly seated on the motherboard?
Have you tried plugging the power connector into another source, an adapter to a molex connector for instance?
The manual for this is sparse at best on information regarding the power connector. Being a three wire connection one of those wires should be the sense which tells it when to turn on. If this is the case your motherboard is what controls the on/off function of the cooler.
Just curious here, have you looked in the Event Viewer to see what errors are appearing at the time that the computer is shutting down?
