Just upgraded my case and added a water cooling system to my PC. Today I was just listening to music when the sound cut off and the computer just died on me. It won't boot at all. Any suggestions on what can be possibly wrong? I have an ASRock z77 Extreme3 LGA1155 motherboard and a Corsair 500 Modular Power Supply. It was just functioning fine and now it's just dead. Really want this back up and running!!!
