I purchased and installed a "Thermaltake Pacific RL120 Water Cooling Kit" in my computer, and it worked perfectly fine for past 6 months. Just few days ago though, my computer overheated and turned itself off. I realized that there was air in the pipes that may have caused water to not pump properly and therefore the overheating the system.
I filled more liquid to get rid of air, and in the process found out that one of the pipe was loose. I drained the water loop and redid the entire loop (this time everything is perfectly fit). Now, when I turn on the power the water won't pump back up
